Hello,

Try the following code.
ASPX:

<asp:FormView ID="FormView1" runat="server"  DefaultMode="Insert" BorderColor="Red" Height="76px" Width="425px">
 <InsertItemTemplate>
  <telerik:RadComboBox ID="RadComboBox1" runat="server" DataSourceID="SqlDataSource1" AutoPostBack="true" AllowCustomText="true" DataTextField="CustomerID" DataValueField="CustomerID" CheckBoxes="True" Text='<%# Bind("ContactName") %>'>
   <ItemTemplate>
     <telerik:RadTreeView ID="RadTreeView1" runat="server">
      <Nodes>
       <telerik:RadTreeNode Text="A">
       </telerik:RadTreeNode>
       <telerik:RadTreeNode Text="B">
        <Nodes>
         <telerik:RadTreeNode Text="B1">
         </telerik:RadTreeNode>
         <telerik:RadTreeNode Text="B2">
         </telerik:RadTreeNode>
        </Nodes>
       </telerik:RadTreeNode>
       <telerik:RadTreeNode Text="C">
       </telerik:RadTreeNode>
      </Nodes>
      </telerik:RadTreeView>
     </ItemTemplate>
   </telerik:RadComboBox>
 </InsertItemTemplate>
</asp:FormView>

Hi Jow,

To learn how a RadTreeView template could be implemented inside of a RadComboBox, you could refer to the code implementation of the following online demo: Demo / RadTreeView in RadComboBox, and to the following Code Library example: CL / RadTreeView in RadComboBox.

I hope this helps.

All the best,
