Nesting Datalist

Use the .aspx code below to bind datalist inside a datalist.

<asp:DataList ID="lstPanels" runat="server" RepeatColumns="1" RepeatDirection="Horizontal"
      DataKeyField="PanelID" OnItemDataBound="lstPanelsItemDataBound">

<asp:DataList ID="SubDataList" runat="server" RepeatColumns="1" RepeatDirection="Horizontal">
   <ItemTemplate>
<ul><li><a class="various" href='<%# "TestDesc.aspx?Testid=" + Eval("TestID") %>'>
      <%#Eval("TestName")%>
      </a></li> </u>
    </ItemTemplate>
    </asp:DataList>

   <ItemTemplate>
   </ItemTemplate>
   </asp:DataList>

Write the C# code to implement the functionality

 protected void lstPanelsItemDataBound(object sender, DataListItemEventArgs e)
    {
         if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
         int PanelID = Convert.ToInt32(lstPanels.DataKeys[e.Item.ItemIndex]);
    // This will fetch the datakey on ItemDataBoundb event
        DataList SubDataList = e.Item.FindControl("SubDataList") as DataList;
        DataTable dtTests = GetDatatable(Convert.ToInt32(PanelID));
 // GetDatatable is a function which will get the data into the datatable
              if (dtTests.Rows.Count > 0)
            {
                SubDataList.DataSource = dtTests;
                SubDataList.DataBind();
            }
         }
   }
