I have created a telerik RadGrid in asp .net. My requirement is to give my own color to Column header. How can we achieve this...? Below is the code structure I'm using.

  <Telerik:RadGrid ID="RadGrid2" runat="server">
     <MasterTableView Width="100%" DataKeyNames="CustomerID" AllowMultiColumnSorting="True">

            <DetailTables>
                <telerik:GridTableView DataKeyNames="OrderID" Name="Orders" Width="100%">

                    <DetailTables>
                        <telerik:GridTableView DataKeyNames="OrderID" Name="OrderDetails" Width="100%">
                            <Columns>
                                <telerik:GridBoundColumn SortExpression="UnitPrice" HeaderText="Unit Price" HeaderButtonType="TextButton" DataField="UnitPrice">
                                </telerik:GridBoundColumn>
                                <telerik:GridBoundColumn SortExpression="Quantity" HeaderText="Quantity" HeaderButtonType="TextButton" DataField="Quantity">
                                </telerik:GridBoundColumn>
                            </Columns>
                        </telerik:GridTableView>
                    </DetailTables>

                    <Columns>
                        <telerik:GridBoundColumn SortExpression="OrderID" HeaderText="OrderID" HeaderButtonType="TextButton" DataField="OrderID">
                        </telerik:GridBoundColumn>
                        <telerik:GridBoundColumn SortExpression="OrderDate" HeaderText="Date Ordered" HeaderButtonType="TextButton" DataField="OrderDate" UniqueName="OrderDate" DataFormatString="{0:D}">
                        </telerik:GridBoundColumn>
                    </Columns>

                </telerik:GridTableView>
            </DetailTables>

            <Columns>
                <telerik:GridBoundColumn SortExpression="CustomerID" HeaderText="CustomerID" HeaderButtonType="TextButton" DataField="CustomerID">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn SortExpression="ContactName" HeaderText="Contact Name" HeaderButtonType="TextButton" DataField="ContactName">
                </telerik:GridBoundColumn>
            </Columns>

        </MasterTableView>
    </telerik:RadGrid>

And it should looks like image below: enter image description here

  • I added in a step 0, so make sure you see that. The Grid folder that I'm asking you to include allows your custom css class to mimic the default one from telerik, but make the background adjustment without breaking our custom functionality. – KreepN Jan 24 '12 at 17:23

Telerik automatically uses a skin for its grid. If you have not specified a skin it will use the Grid.Default skin. You can modify this skin or any of the skins to your own custom style. Just follow these steps.

  • Change the properties in the css file. (The default grid skin is called Grid.Default.css. On my computer it is found in the folder where I have the telerik RadControls for ASP.NET AJAX in the folder Skins\Default.) In this case, change the css something like this:

Grid.Default.css (line 59)

.RadGrid_Default .rgHeader,
.RadGrid_Default th.rgResizeCol
{
  border:0;
  border-bottom:1px solid #828282;
  background-color: Red;
  /* background:#eaeaea 0 -2300px repeat-x url('Grid/sprite.gif'); */
}

  • Add a link to the css file that you modified on the page where you have your grid (or in the master page). <link href="Grid.Default.css" rel="stylesheet" type="text/css" />

  • Add the property EnableEmbeddedSkins="false" to your RadGrid. <telerik:RadGrid ID="RadGrid1" EnableEmbeddedSkins="false" runat="server"> This will tell the page to use your modified css file instead of the embedded one.

Telerik's web site has a blog post called How To Override Styles in a RadControl for ASP.NET AJAX' Embedded Skin that explains in detail how to override an existing style.

A VERY EASY way to achieve your results is to use...

<ItemStyle BackColor="Red"/>

And

<AlternatingItemStyle BackColor="Red"/>

Here is your code with the tags inserted...

  <Telerik:RadGrid ID="RadGrid2" runat="server">
     <MasterTableView Width="100%" DataKeyNames="CustomerID" AllowMultiColumnSorting="True">

            <ItemStyle BackColor="Red"/>
            <AlternatingItemStyle BackColor="Red"/>

            <DetailTables>
                <telerik:GridTableView DataKeyNames="OrderID" Name="Orders" Width="100%">

                    <DetailTables>
                        <telerik:GridTableView DataKeyNames="OrderID" Name="OrderDetails" Width="100%">
                            <Columns>
                                <telerik:GridBoundColumn SortExpression="UnitPrice" HeaderText="Unit Price" HeaderButtonType="TextButton" DataField="UnitPrice">
                                </telerik:GridBoundColumn>
                                <telerik:GridBoundColumn SortExpression="Quantity" HeaderText="Quantity" HeaderButtonType="TextButton" DataField="Quantity">
                                </telerik:GridBoundColumn>
                            </Columns>
                        </telerik:GridTableView>
                    </DetailTables>

                    <Columns>
                        <telerik:GridBoundColumn SortExpression="OrderID" HeaderText="OrderID" HeaderButtonType="TextButton" DataField="OrderID">
                        </telerik:GridBoundColumn>
                        <telerik:GridBoundColumn SortExpression="OrderDate" HeaderText="Date Ordered" HeaderButtonType="TextButton" DataField="OrderDate" UniqueName="OrderDate" DataFormatString="{0:D}">
                        </telerik:GridBoundColumn>
                    </Columns>

                </telerik:GridTableView>
            </DetailTables>

            <Columns>
                <telerik:GridBoundColumn SortExpression="CustomerID" HeaderText="CustomerID" HeaderButtonType="TextButton" DataField="CustomerID">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn SortExpression="ContactName" HeaderText="Contact Name" HeaderButtonType="TextButton" DataField="ContactName">
                </telerik:GridBoundColumn>
            </Columns>

        </MasterTableView>
    </telerik:RadGrid>

I had the same issue and even after overriding the class, the header color did not change.

.RadGrid_Default .rgHeader { background-color: rgb(236, 89, 91); }

I found that my overridden background was re-overridden by Grid. I used !important keyword not to allow Grid to re-override my class

.RadGrid_Default .rgHeader { background-color: rgb(236, 89, 91) !important; }

Same you can do for any class!

We meet again!:

Step 0: (Added via edit) Navigate to the following install folder and add the grid folder to your project)

C:\Program Files\Telerik\RadControls for ASP.NET AJAX Q3 2011\Skins\Default

enter image description here

Results of what I managed to produce

enter image description here

Step 1: Create a stylesheet, I named mine Grid.Default.css and link it in your .aspx page between the head tags.

<head>
   <link href="Grid.Default.css" rel="stylesheet" type="text/css" />
</head>

Step 2: Open said style sheet and paste this verbatim:

/*Telerik RadGrid Default Skin*/

/*global*/

Step 3: Go to your grid and set your css class to default and turn off embedded skins:

<telerik:RadGrid ID="RadGrid1" runat="server" oninit="RadGrid1_Init" 
        onneeddatasource="RadGrid1_NeedDataSource" CssClass="Default" 
        EnableEmbeddedSkins="False">

Step 4: Run it. (If you wish to adjust the color I used, as I tried to get it as close as possible to the one in your screenshot, see below.)

NOTE: To change the color modify this declaration in the css class:

.RadGrid_Default .rgHeader 
{
   background-color: rgb(236, 89, 91);
}
