Chart Controls in ASP.Net

I was looking at creating chart controls for implementing in the .Net web applications. I didn’t like to use the 3^rd party tools or any freeware tools. Well, while browsing found a cool feature provided by MICROSOFT for the same.

In this article, we will have a look at the CHART CONTROLS in .Net applications.

Pre-requisites
Ø  Visual Studio 2008 SP1, Link to download
Ø  .NET Framework 3.5 SP1, Link to download
Ø   Microsoft Chart Controls, Link to download
Ø  Visual Studio 2008 Add-on for the Chart Controls, Link to download
Ø  Documentations by Microsoft, Link to download
Ø  Web and Windows Application Samples, Link to download

Types of Charts
Ø  Area Charts
Ø  Bar column Charts
Ø  Circular Charts
Ø  Combination Charts
Ø  Data Distribution Charts
Ø  Error Bar
Ø  Financial Charts
Ø  Line Charts
Ø  Pie Doughnut Charts
Ø  Point Charts
Ø  Price Range Financial Charts
Ø  Pyramid Funnel Charts
Ø  Range Charts

Examples

The examples provided by Microsoft are very clear and easy. Hence you can download and try the samples. Also, the control is easy to use, just drag and drop the control and start using it.

Namespace

The namespace which we use here is System.Web.UI.DataVisualization.Charting.

More about Chart Controls
Ø  This control is not available for Visual Studio 2005.
Ø  It is available as a native component in Microsoft Visual Studio 2008 SP1.  First you have to install the Chart Controls provided by Microsoft and then the add-ons for using the control.
Ø  But in Visual Studio 2010, it is present as inbuilt component. We can just use it!

Change the Color of a Column in a List in SharePoint

In this article, we will know how to change the color of a column based upon the values in the column. It is something like “Color Indicator” in SharePoint.

Scenario:

We have a custom list used for Project Tracking. In the list, we have column named STATUS for tracking the project.

Whenever an item in the list is updated with the status in the column, then the background color of the status column should automatically change depending upon the status. Hence it gives a better UI for tracking the status.
Solution:

1. Create a custom list named “Project Tracking System” with the columns such as “Title”, “Description” and Status with the data type as shown below:

Columns with the data types to be created:

2. Now, we will insert 4-5 items in the list created. 

In the above list, we can see that the status column is updated, but it would be good when we have background color of the each status separately. It is gives easy tracking to the users.

3. We can achieve this through JAVA SCRIPT

4. Add a Content Editor Web part below the list as shown below:

5. Now in the content editor web part, add the below java script code (Open the tool pane->Source Editor->Place the Java Script->Click Ok) and save the page.
Add the below code in the script JavaScript tag

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

var colorCode = document.getElementsByTagName("td")// finding all the TD tags var i=0; for (i=0;i { if (colorCode[i].className=="ms-vb2") { if (colorCode[i].innerHTML=="Not Started")//finding the word to which the color has to be set { colorCode[i].style.backgroundColor='lightblue'; // setting the color depending upon the value colorCode[i].style.color='Black'; // setting the color of the words inside the content } if (colorCode[i].innerHTML=="Started") { colorCode[i].style.backgroundColor='Brown'; colorCode[i].style.color='Black'; } if (colorCode[i].innerHTML=="In Progress") { colorCode[i].style.backgroundColor='Orange'; colorCode[i].style.color='Black'; } if (colorCode[i].innerHTML=="Completed") { colorCode[i].style.backgroundColor='green'; colorCode[i].style.color='Black'; } if (colorCode[i].innerHTML=="Deffered") { colorCode[i].style.backgroundColor='Red'; colorCode[i].style.color='Black'; } } }

6. Now, you can see the status column background is changed depending upon the status inserted for each item as shown below:

It gives good interface to the users and also we can categorize the status easily.

Remote Blob Storage (RBS) in SharePoint 2010

In this article, we will know about a new feature in SharePoint 2010 which allows the remote storage in SharePoint.

What is Remote BLOB Storage?
     Ø  BLOB – Binary Large Object

Ø  Remote BLOB Storage (RBS) is a library API set that is incorporated as an add-on feature pack for Microsoft SQL Server.

Ø  It can be run on servers with Microsoft SQL Server 2008 R2, SQL Server 2008 or SQL Server 2008 R2 Express. To run RBS on a remote server, you must be running SQL Server 2008 R2 Enterprise edition.

Ø  RBS is not supported for Microsoft SQL Server 2005.

Ø  In Microsoft SharePoint Server 2010, RBS can be used for content databases only.

Why RBS?

It provides the following benefits:

Ø  BLOB data can be stored on less expensive storage devices that are configured to handle simple storage.

Ø  The administration of the BLOB storage is controlled by a system that is designed specifically to work with BLOB data.

Ø  Database server resources are freed for database operations.

When to Go for RBS?

Ø  Large Database of Mostly Binary Data

Ø  Digital Asset Management Databases

Ø  When Storage Tiers Need to be Implemented

Ø  When Storage Needs to be Optimized

You can expect to benefit from RBS in the following cases:

Ø  The content databases are larger than 500 gigabytes (GB).

Ø  The BLOB data files are larger than 256 kilobytes (KB).

Ø  The BLOB data files are at least 80 KB and the database server is a performance bottleneck. Then, RBS reduces the both the I/O and processing load on the database server.

RBS Advantages over EBS (External Blob Storage)

Hope this explains about the basics of RBS in SharePoint 2010.

I came across a good article explaining about Configuring Remote Blob Storage for SharePoint 2010. Here is the link.

CAML Query to Get Data from SharePoint List

To know about the Basics of the CAML query read this article.

To know about using CAML query builder to create CAML queries, read this article.

Scenario:

I have a custom list named “Product List” with the columns named Title, Price, Quantity and Is Available.

I want to retrieve the products with price greater than 1000 and lesser than 10000. Then I have to order the results depending upon the quantity in descending order.

Using the CAML query builder, I have created a CAML query for the above scenario and the query is as follows:

<Query><Where><And><Gt><FieldRef Name="Price" /><Value Type="Number">1000</Value></Gt><Leq><FieldRef Name="Price" /><Value Type="Number">10000</Value></Leq></And></Where><OrderBy><FieldRef Name="Price" Ascending="False" /></OrderBy></Query>
