How to give a color to the Column Header in Telerik RadGrid

Question

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:

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.
