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.

In this article, we will learn how to use CAML query in Microsoft Visual Studio

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>

Implementing CAML Query in Microsoft Visual Studio

                        }

                    }
                    Console.ReadLine(); 
                }

CAML Query tutorial for SharePoint

In this article, we will understand the basics of CAML query in SharePoint.

What is CAML?

  Ø  CAML - Collaborative Application Markup Language

  Ø  XML- Extensible Markup Language based query language

  Ø  Used to perform a query operation against SharePoint Lists

How SharePoint List Items are retrieved?

SharePoint List data can be retrieved in any one of the following ways:

1. Using the SharePoint object model – used when code runs on the server (Example: Developing a web part or an application page)

2. Using the SharePoint Lists web service – used when your code doesn’t run on the server where the SharePoint is installed (Example: Developing a windows application)

3. Using Power shell –used mostly by the ADMIN of the SharePoint when they quickly want to retrieve some information from the SharePoint site

How does CAML query looks like?

As I already mentioned, it is XML based query language and it contains tags in it. The root element of the CAML query root element is Query. But it is not necessary to use Query element in the query you form.

Within the Query element you have two elements possible:

1. Where   – to filter the data

2. OrderBy – to categorize the data

A simple structure of the CAML query is as follows:
<Query>

          <Where>

                   <Eq>

                             <FieldRef Name=”FieldName” />

                             <Value Type=”DataType”>Value</Value>

                   </Eq>

          </Where>

          <OrderBy>

                             <FieldRef Name=”FieldName” />

                             <FieldRef Name=”FieldName” />

          </OrderBy>

</Query>

Operators in CAML Query

From the above structure, we came to know that it uses Where and OrderBy elements to retrieve the data from the list.

Let us know about the operators present in the CAML query and its usage:

Inside the Where element

1. Logical Operators - AND, OR

2. Comparison Operators - Listed Below in the table

AND – Which takes two conditions are satisfied

OR – Which takes when either of the conditions is satisfied

Comparison Operators

Inside the OrderBy/GroupBy element

OrderBy – Which orders or sort the data depends upon the field (FieldRef element) given.

GroupBy – Which groups the data depends upon the group by field (FieldRef element) given.

Examples

Logical & Comparison Operators

Use of AND, Gt, Leq

<Query>

<Where>

<And>

<Gt>

<FieldRef Name="Quantity" />

<Value Type="Number">0</Value>

</Gt>

<Leq>

<FieldRef Name="Price" />

<Value Type="Number">2000</Value>

</Leq>

</And>

</Where>

</Query>

Use of OR, Gt, Leq

<Query>

<Where>

<Or>

    <Gt>

<FieldRef Name="Quantity" />

<Value Type="Number">0</Value>

    </Gt>

                     <Leq>

  <FieldRef Name="Price" />

<Value Type="Number">2000</Value>

    </Leq>

               </Or>

       </Where>

</Query>

Use of BeginsWith, Leq

<Query>

<Where>

<And>

     <BeginsWith>

 <FieldRef Name="Title" />

 <Value Type="Text">M</Value>

     </BeginsWith>

     <Leq>

    <FieldRef Name="Quantity" />

<Value Type="Number">1000</Value>

     </Leq>

</And>

</Where>

<OrderBy>

<FieldRef Name="Price" Ascending="False" />

</OrderBy>

</Query>

OrderBy Operator
<Query>

<Where>

<Or>

   <Gt>

<FieldRef Name="Quantity" />

<Value Type="Number">0</Value>

  </Gt>

    <Leq>

<FieldRef Name="Price" />

<Value Type="Number">2000</Value>

  </Leq>

</Or>

</Where>

<OrderBy>

<FieldRef Name="Price" Ascending="True" />

</OrderBy>

</Query>

Is it possible to write this queries without any errors manually?

Yes. But we will know the errors only after executing the program. Hence there is a free CAML query builder which will generate the query easily.
