问题:

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.

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>


回答3:

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

Results of what I managed to produce

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*/

.GridRowSelector_Default
{
    background:#4c4e54;
}

/*row drag n drop*/

.GridItemDropIndicator_Default
{
    border-top:1px dashed #666;
}

/*tooltip*/

.GridToolTip_Default
{
    border:1px solid #828282;
    padding:3px;
    background:#fff;
    color:#333;
}

/*rtl*/

.RadGridRTL_Default .rgPageFirst
{
    background-position:0 -1000px;
}
.RadGridRTL_Default .rgPageFirst:hover
{
    background-position:0 -1050px;
}
.RadGridRTL_Default .rgPagePrev
{
    background-position:0 -850px;
}
.RadGridRTL_Default .rgPagePrev:hover
{
    background-position:0 -900px;
}
.RadGridRTL_Default .rgPageNext
{
    background-position:0 -700px;
}
.RadGridRTL_Default .rgPageNext:hover
{
    background-position:0 -750px;
}
.RadGridRTL_Default .rgPageLast
{
    background-position:0 -550px;
}
.RadGridRTL_Default .rgPageLast:hover
{
    background-position:0 -600px;
}

.RadGridRTL_Default .rgExpand
{
    background-position:-20px -496px;
}

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);
}
