Main Page

Web server controls such as the Repeater, DataList, and GridView controls allow you to specify templates, which are HTML elements that define the layout for a particular portion of the control. For example, in the GridView control, you can define templates for items, selected items, alternating items, and so on, so that each of these elements can have a custom look.

NoteNote

For background information about templates, see ASP.NET Web Server Controls Templates

To create a Web server control template using ASP.NET syntax

  1. In the ASP.NET page, insert an element inside the control to identify what template you are creating, as shown in the following example:

    Visual BasicВ CopyCode imageCopy Code
    <asp:DataList id="DataList1" runat="server">
  <ItemTemplate>
  
  </ItemTemplate>
</asp:DataList>
    C#В CopyCode imageCopy Code
    <asp:DataList id="DataList1" runat="server">
  <ItemTemplate>
  
  </ItemTemplate>
</asp:DataList>

  2. Inside the template element, add HTML text and other controls as the template's content. Include property and data-binding values for the embedded controls using normal syntax, as shown in the following example:

    Visual BasicВ CopyCode imageCopy Code
    <asp:DataList id="DataList3" runat="server">
   <ItemTemplate>
    Name: <asp:Label ID="Label2" runat="server" 
    Text='<%# DataBinder.Eval(Container, "DataItem.EmployeeName")%>'/>
   </ItemTemplate>
</asp:DataList>
    C#В CopyCode imageCopy Code
    <asp:DataList id="DataList3" runat="server">
   <ItemTemplate>
    Name: <asp:Label ID="Label2" runat="server" 
    Text='<%# DataBinder.Eval(Container, "DataItem.EmployeeName")%>'/>
   </ItemTemplate>
</asp:DataList>

  3. Repeat Steps 1 and 2 for each template you want to create.

    The following example shows a complete declaration for a DataList Web server control with simple templates declared for the Header, Item, and Separator templates.

    Visual BasicВ CopyCode imageCopy Code
    <asp:datalist id="DataList2" runat="server" >
   <HeaderTemplate>
   Items matching your query: 
   </HeaderTemplate>
   <ItemTemplate>
   Name: <asp:Label id="Label1" runat="server" 
     Text='<%# DataBinder.Eval(Container, "DataItem.EmployeeName")%>'></asp:Label>
   </ItemTemplate>
   <SeparatorTemplate>
     <br><hr>
   </SeparatorTemplate>
</asp:datalist>
    C#В CopyCode imageCopy Code
    <asp:datalist id="DataList2" runat="server" >
   <HeaderTemplate>
   Items matching your query: 
   </HeaderTemplate>
   <ItemTemplate>
   Name: <asp:Label id="Label1" runat="server" 
     Text='<%# DataBinder.Eval(Container, "DataItem.EmployeeName")%>'></asp:Label>
   </ItemTemplate>
   <SeparatorTemplate>
     <br><hr>
   </SeparatorTemplate>
</asp:datalist>
