Hello Esther Nirmala,

The solution is to use ItemTemplates - CheckBox and Label as this:

<telerik:RadComboBox ID="RadComboBox1" runat="server">
            <ItemTemplate>
                <div onclick="StopPropagation(event)">
                    <asp:CheckBox runat="server" ID="chk1" Checked="true" onclick="onCheckBoxClick(this)" />
                    <asp:Label runat="server" ID="Label1" AssociatedControlID="chk1" Text='<%# DataBinder.Eval(Container,"Text") %>'/>
                </div>
            </ItemTemplate>
            <Items>
                <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1" Value="RadComboBoxItem1" />
                <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem2" Value="RadComboBoxItem2" />
                <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem3" Value="RadComboBoxItem3" />
                <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem4" Value="RadComboBoxItem4" />
            </Items>
        </telerik:RadComboBox>

To prevent the ComboBox of closing when you click on one of the items use this:

<script type="text/javascript">
        function StopPropagation(e)
            {
                //cancel bubbling
                e.cancelBubble = true;
                if (e.stopPropagation)
                {
                    e.stopPropagation();
                }
            }
        </script>

You may find the full code in the attached .zip file.

Hope this helps.
