Changing Favicon in SharePoint 2010

May 03, 2012 Marudu 3 comments

What is Favicon?

All the top websites in the internet will have their favicon in the address bar. Similarly SharePoint 2010 sites also have its favicon in the address bar as shown below:

What is the use of Favicon?

When we are saving a site as a favorite then this icon will be saved for the reference with the site name starting in the favorites bar in any web browser. For example: Take Google you will see the Google symbol in the address bar.

How to create Favicon (.ico file)?
I have used this website http://www.coolutils.com/online/image-converter/ for converting the image to .ico file which is favicon file. You can upload your company’s logo and convert it into .ico file in the mentioned site and download it from the site. (You can use any free convertors site online to create the icon file)

How to set Favicon in the SharePoint 2010 site?

SharePoint 2010 displays an orange Favicon and it is present in the following folder C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\IMAGES\favicon.ico

It will look like as follows:

Now, navigate to the above path and search for favicon.ico and rename the file to FaviconBackup.ico.

Now copy your favicon (.ico file) to this folder and make sure it is named as "favicon.ico".

Now refresh your SharePoint site and you will see the new favicon displayed in the address bar.

How to display different Favicons for different sites in the server farm?

The only way is we will change the favicon in the master page inorder to set different favicons for different sites.

Hence, edit the V4.master page file in the SharePoint designer and check out the file and look for the following in the code view:

<SharePoint:SPShortcutIcon runat="server" IconUrl="/_layouts/images/favicon.ico"/>

Now,upload the favicon file in the image library or store the file with different name in this folder. C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\IMAGES\newfavicon.ico
<SharePoint:SPShortcutIcon runat="server" IconUrl="/_layouts/images/ newfavicon.ico "/>

Give thenew URL in the tag and save the master page and check in the file.

Refresh the SharePoint page and now you can set the different favicon for more than one site in the SP farm.

Programmatically get SharePoint Users with Group Name

May 03, 2012 Marudu 6 comments

In this article, we will come to know how to list all the users from the SharePoint site using c#.

Scenario:

We have to retrieve all the Users from the SharePoint site with the Group Name using object model.

Solution:

I have created a console application which will group the users with the Group Name and also display the User details.
Code (.cs):

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;

namespace UserPermissions_Console
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {                
                    GetUsersGroups();                
            }
            catch (Exception ex)
            {
                Console.WriteLine("Error Occured: " + ex.Message);
            }
        }
        private static void GetUserRoles()
        {
            using (SPSite site = new SPSite("http://sitename"))
            {

                SPWeb web = site.OpenWeb();
                Console.WriteLine("\n\n Roles Assignments:");

                foreach (SPRoleAssignment roleA in web.RoleAssignments)
                {
                    Console.WriteLine("The following Role definition bindings exist for" + roleA.Member.Name);                    
                    foreach (SPRoleDefinition roledef in roleA.RoleDefinitionBindings)
                    {
                        Console.WriteLine(roledef.Name);                    
                    }
                }
                Console.ReadLine();
            }
        }
        private static void GetUsersGroups()
        {   
            using (SPSite site = new SPSite("http://sitename"))
            {

                SPWeb web = site.OpenWeb();
                SPGroupCollection groupCollection = web.SiteGroups;
                
                foreach (SPGroup group in groupCollection)
                {
                    SPUserCollection userCollection = group.Users;
                    Console.WriteLine("Group Name :" + group.Name+"\n");
                    
                    foreach (SPUser user in userCollection)
                    {
                        Console.WriteLine("User Name: " + user.Name + " Email: " + user.Email + " Login: " + user.LoginName);
                    }
                }
                //Iterate the owners group
                SPGroup ownerGroup = web.AssociatedOwnerGroup;                
                foreach (SPUser ownerUser in ownerGroup.Users)
                {
                    Console.WriteLine("User Name: " + ownerUser.Name + " Email: " + ownerUser.Email + " Login: " + ownerUser.LoginName);
                }
            }
            Console.ReadLine();
        }

    }
}

RegisterForEventValidation can only be called during Render()

May 01, 2012 Marudu No comments

To know about creating a Grid view with Paging and Exporting the view to Word and Excel documents read this article.
The following is the screen shot which you get due to this error:

This error occurs whenever we are trying to render control to response. To fix this problem I have added EnableEventValidation="false" to @Page directive of aspx page.

This will look like as follows:

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" EnableEventValidation="false" %>

This code will fix this issue.

Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server

May 01, 2012 Marudu No comments

To know about creating a Grid view with Paging and Exporting the view to Word and Excel documents read this article.
The following is the screen shot which you get due to this error:

This error occurs whenever you are trying to export the grid view data to excel or word. This occurs due to the reason that the compiler thinks that the control is not added in the form. Hence to resolve this issue, add the overriding function in the code

public override void VerifyRenderingInServerForm(Control control)
{
  /* Verifies that the control is rendered */
}

This code will fix this issue.

Grid View with Paging into Excel and Word in ASP.Net

May 01, 2012 Marudu 1 comment

After reading this article, you will come to know the following:

1. Using grid view control in the ASP.Net applications

2. Creating and connecting the SQL database in the ASP.Net applications

3. Creating PAGING in the grid view

4. Tabbed navigation in the ASP.Net application with single GRIDVIEW

5. Converting the grid view with paging to WORD and EXCEL document

Scenario:

1. We have to use grid view to display the details from the SQL database

2. We have to use single grid view control to display details from two different tables from the database

3. We have to enable PAGING in the grid view control

4. We have to convert the details displayed in the grid view to word and excel document

Solution:

1. I have created an ASP.Net Web application using Microsoft Visual Studio 2005.

2. I have placed two buttons (as tabbed navigation) for displaying the details from two different tables in two tabs.

3. Also, you will find the solution for paging in the grid view control.

4. Then, after displaying the details, we can convert the details to word and excel document.

Code (.cs file):

public partial class _Default : System.Web.UI.Page
{ 
    String strDetails = String.Empty;
    SqlConnection conn = new SqlConnection("Data Source=ServerName;Initial 
    Catalog=Database Name;Integrated Security=True");
    protected void Page_Load(object sender, EventArgs e)
   {
        if (!IsPostBack)
        {
            BindData(strDetails);
        }       
        GridView1.PageIndexChanging += new GridViewPageEventHandler(GridView1_PageIndexChanging);
    }        
    protected void btn1_Display_Click(object sender, EventArgs e)
    {
        strDetails = "";
        GridView1.PageIndex = 0;
        BindData(strDetails);
    }
    protected void btn2_Dipslay_Click(object sender, EventArgs e)
    {
        strDetails = "UserGroup";
        GridView1.PageIndex = 0;
        BindData(strDetails);
    }    
    protected void btn_ExportExcel_Click(object sender, EventArgs e)
   {              
        Response.Clear();
        Response.AddHeader("content-disposition","attachment;filename=FileName.xls");
        Response.Charset = "";
        Response.ContentType = "application/vnd.xls";
        System.IO.StringWriter stringWrite = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter htmlWrite =new HtmlTextWriter(stringWrite);
        //turn off paging before exporting the details
        GridView1.AllowPaging = false;
        strDetails = ViewState["strDetailsValue"].ToString();
        BindData(strDetails);
        GridView1.RenderControl(htmlWrite);
        Response.Write(stringWrite.ToString());
        Response.End();
        //turn the paging on again after writing the values to the excel document
        GridView1.AllowPaging = true;
        BindData(strDetails);
        Response.Flush();
   }
    protected void btn_ExportWord_Click(object sender, EventArgs e)
   {
        Response.Clear();
        Response.AddHeader("content-disposition", attachment;filename=FileName.doc");
        Response.Charset = "";
        Response.ContentType = "application/vnd.ms-word ";
        StringWriter sw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(sw);
        //turn off paging before exporting the details
        GridView1.AllowPaging = false;
        strDetails = ViewState["strDetailsValue"].ToString();
        BindData(strDetails);
        GridView1.RenderControl(hw);
        Response.Write(sw.ToString());
        Response.End();
        //turn the paging on again after writing the values to the excel document
        GridView1.AllowPaging = true;
        BindData(strDetails);
        Response.Flush();        
    }
    private void BindData(String strDetails)
    {
        DataSet ds = new DataSet();
        conn.Open();
        SqlCommand cmd;
        if (strDetails == "UserGroup")
        {
            cmd = new SqlCommand("Select * from table1", conn);
        }
        else
        {
            cmd = new SqlCommand("Select * from table2", conn);
        }
        SqlDataAdapter sqlAd = new SqlDataAdapter(cmd);
        sqlAd.Fill(ds);
        GridView1.Controls.Clear();
        GridView1.DataSource = ds.Tables[0];
        GridView1.DataBind();
        GridView1.Visible = true;
        ViewState.Add("strDetailsValue", strDetails);
        conn.Close();

   //Handling the paging event in the grid view control 
    protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        GridView1.PageIndex = e.NewPageIndex;
        strDetails = ViewState["strDetailsValue"].ToString();

New features of SharePoint Designer 2010

April 22, 2012 Marudu No comments

Read this article, to know the Basics of Workflow in SharePoint.

Read this article, to know about Implementing Designer workflow in SharePoint using SharePoint designer 2007.

In this article, we will come to know about the new features added in the SharePoint designer 2010 for the workflow.

What is new in workflows in SharePoint Designer 2010?

In the SharePoint 2010 designer you will see a ‘ Work flows’ tab in the ribbon on the top. Now you can create three types of workflow in SharePoint 2010 using designer 2010:

Ø List Workflow – This is associated with a specific list or libraries in SharePoint.

Ø Reusable Workflow – This type of workflow can be associated with multiple lists or content types. It is more flexible than the List workflow type. Later this content type can be used with a list. One more advantage of this type of work flow is you can import it to Visual Studio and we can write code to enhance this type of workflow.

Ø Site Workflow – This workflow is not associated with any lists or site content types and can be started from All Site content in the page i.e., it operates on the site level.

When you create a workflow, you will see the following new options in the ribbon which makes the user to create and trouble shoot the workflow in SharePoint very easily.

Now let us know about the new options for implementing the workflow in SP 2010 designer. Particularly in the ribbon interface.

Save button – Now you can save the workflow. This option was not available in SharePoint Designer 2007.
Publish button – By clicking the publish button, you can publish the workflow to the SharePoint site.
Condition – Here you can implement the conditions for the workflow.
Action – Here you can add multiple actions when a specific condition occurs in the workflow.
Export to Visio – Using this option, you can convert a workflow and show it in a diagrammatic representation to the user which gives clear understanding, actions, process, people involved and status of the workflow.
Initiation Form Parameters – you can define the starting parameters for the workflow.
Local Variables – Here you can define the internal variables of the workflow using this option.

Workflow using SharePoint designer 2007

April 16, 2012 Marudu No comments

To know about the basics of the Work flows in SharePoint, read this article.

In this article, we will learn how to create a designer workflow in SharePoint designer 2007.

Scenario:

1. Create a workflow in SharePoint designer 2007

2. This workflow should be automatically triggered when an item is created or updated in a SharePoint Document library

3. When the workflow is initiated, then the document created or updated in the document library should be copied to another document library

4. Also, we will have parameter (flag) in the document library whether to move or not in the document library.

Solution:

We will create two document libraries named, “Draft Library” and “Publish Library”.

In the Draft Library we will create an additional column named Move to Publish Library of type Choice menu (YES or NO)

When a document is uploaded or updated in Draft Library with the flag value equals to yes, then the workflow should be triggered which will copy the item to the Publish Library.

Steps:

Open the SharePoint site in the designer and click on File -> New -> Workflow

Give the name of the workflow and Select the document library for the workflow to be associated (Draft Library in our case). Then Select two options Automatically starts the workflow when an item is created or change and click on Next.

In the Step1, click on the conditions and select Compare Draft Library field

Now, select the Move to Publish Library column and Value equals to Yes as shown below

Now we will apply the action for the workflow. Click on Actions -> Copy List Item.

Now select Draft Library to Publish Library in the values as shown below

Once you click on finish, then the workflow will be associated to the “Draft Library”.

Navigate to the SharePoint Document library and when you check the workflow settings, and then you will see the MoveDocuments workflow associated with the Draft document library.

Now, we will test the workflow. Go ahead and upload a document into the “Draft Library”. Select YES in the Move to Publish Library option as shown below:

Now, our workflow will be initiated and you will see the status of the workflow (completed) in the document library as shown below:

Click on the completed in the document library where you will be navigated to the workflow information as shown below:

Now, navigate to the publish library, you will see the document being copied as result of the workflow as shown below:

Now, at the end of this article we have learned the following from this article:

1. Creating a Designer workflow in SharePoint using SharePoint designer 2007.

2. Used workflow to copy an item form one document library to another document library.

The security validation for this page is invalid in SharePoint

April 16, 2012 Marudu No comments

Sometimes, when a user with least permissions in the SharePoint site, creates or updates an item, then the following error will be shown:

“The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again”

When you are creating a custom web parts or creating custom solutions, your code will run with your credentials.

Not everybody has full control in the SharePoint site, so when a user has read only rights and try to update an item in the list or SharePoint Document library, then the code will throw an access denied error. This happens, when the code needs access to objects that are not in the scope of the user credentials.

Here comes the concept called impersonation (ability to control the identity under which code is executed) in ASP.Net. This will allow you to run your code with the help of a user who has correct permissions to run it.

Namespace: Microsoft.SharePoint
Assembly : Microsoft.SharePoint (in Microsoft.SharePoint.dll)

In SharePoint we have built-in function to accomplish this: SPSecurity.RunWithElevatedPrivileges, it runs with the System Account User.

Solutions:

1. Add the “SPSecurity.RunWithElevatedPrivileges = True” in the code as shown in the example below:

Check the full code usage in this post http://sharepoint-works.blogspot.com/2011/12/programmatically-creating-site-backup.html

2. Or in the Central Administration -> Application Management -> Web Application General Settings -> Select web application
In Web Page Security Validation, change security validation is off.

Note: The 2^nd solution is should not be followed as per the best practices of SharePoint.

Workflows in SharePoint

April 16, 2012 Marudu No comments

What is a Workflow in SharePoint?

Ø In simple words, we can say workflow is a serious of activities occurs in steps which will produce an output at the final step.

Ø In SharePoint, workflow is an automated movement of documents or items through a sequence of actions or tasks that are related to a business process.

Ø Business process is a sequence of steps that occurs on a document or a task or an item and finally produces a result as an outcome.

Types of Workflows

Basically, there are two fundamental types of workflows in the SharePoint:

1. Sequential workflow

It represents the steps that execute in order until the completion of last activity. It is represented graphically in flowchart with start, end and all the sequential activities in between.

Example

2. State-Machine workflow

It represents a set of states, transitions and actions. As sequential workflows, it does not have prescribed execution flow and need not have an end. It can have any number of states and transition and it can any items related to any transition.

Example

The different types of workflow in the various versions of SharePoint present by default are listed below:

Ways for creating workflows in SharePoint

The different ways of creating the workflows in SharePoint are as follows:

1. In SharePoint site directly

2. SharePoint Designer

3. Microsoft Visual Studio with workflow extensions installed (WWF- Windows Workflow Foundation) – basically called custom workflows

4. Third party tools like K2 Black Perl, Nintex, etc.,

What are the pre-requisites for creating a workflow in SharePoint?

1. There should be a at least one list or document library to create and associate a workflow.

2. If you do not have a single list or document library in your site, you will be prompted for creating a list or library.

3. If you want your workflow to be associated with custom columns or settings in the site, then those changes should be made before you create the workflow so that it will be available in the designer.

Advantages

Ø Allow the business activities to be automated, enabling actions such as document review, approval, issue tracking and signature collection.

Ø Allow the document to be routed to one person to another for approval by assigning a task to each person. This is followed by analysis, review, and approval and finally the document is published. Hence making the document management easier.

Ø Also improves the collaboration in an enterprise.

Exporting SharePoint User Groups with Group Names

April 07, 2012 Marudu 10 comments

In the article Exporting SharePoint User Groups into Excel, we have learned about exporting the SharePoint user groups into excel. Here we are able to export all the users in a SharePoint site but we are unable to sort the users with the group name.

In this article, we will learn a small work around filter the users with the group name.

We can use SQL Query to fetch this data.

Connect to the SQL server and open a new query in the content database where your SharePoint site resides.

The SharePoint content DB does not expose the tables (for lists, libraries, users, etc.) in the database directly.

The below is the query which will fetch all the users in the SharePoint site with the user groups in a separate column in the result.
SELECT dbo.Groups.ID, dbo.Groups.Title, dbo.UserInfo.tp_Title, dbo.UserInfo.tp_Login FROM dbo.GroupMembership INNER JOIN dbo.Groups ON dbo.GroupMembership.SiteId = dbo.Groups.SiteId INNER JOIN dbo.UserInfo ON dbo.GroupMembership.MemberId = dbo.UserInfo.tp_ID

Hope this helps you!
