Hello Bhuvan,

I am not quite sure about your scenario and I suppose that you want to access the CheckBox control which is in side the ItemTemplate.
Here is a sample which demonstrates the same.
aspx:

<telerik:RadComboBox ID="RadComboBox1" >
  <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>

C#:

protected void Button1_Click(object sender, EventArgs e)//accessing the checkboxes in a Button click
  {
      foreach (RadComboBoxItem item in RadComboBox1.Items)
      {
        CheckBox chk= (CheckBox)item.FindControl("CheckBox1");
      }
  }

Thanks,
Shinu.
