  Hi,
  
  I have a combobox with itemtemplate and a div inside that and labels inside div.
  I want to do a required field validation on this? i tried to set empty data text, initial value to the combo text etc. but nothing works.

  Hello Liju,
  Try the following code which worked as expected at my end.
  aspx:
  

  <telerik:RadComboBox ID="RadComboBox1" AllowCustomText="true"

  runat="server" ValidationGroup="ValidationGroup1">

              <ItemTemplate>

                  <asp:CheckBox runat="server" ID="CheckBox1" />

                  <%# DataBinder.Eval(Container, "Text") %>

              </ItemTemplate>

              <Items>

                  <telerik:RadComboBoxItem Value="10/10/2010" Text="10/10/2010" />

                  <telerik:RadComboBoxItem Value="10/3/2010" Text="10/3/2010" />

                  <telerik:RadComboBoxItem Value="10/10/2010" Text="10/10/2010" />

                  <telerik:RadComboBoxItem Text="Date1" IsSeparator="true" />

              </Items>

  </telerik:RadComboBox>

  <asp:RequiredFieldValidator runat="server" ID="RequiredFieldValidator4" ControlToValidate="RadComboBox1"

              ErrorMessage="Please select a Date."  ValidationGroup="ValidationGroup1"/>

   <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" ValidationGroup="ValidationGroup1" />

  
  Also take a look at the following help article.
  validation.
  
  Thanks,
