Get button click event in itemTemplate in radToolBar

[Shannnon]

I have two button in RadComboBox in RadToolBarButton ItemTemplate:

<telerik:RadToolBarButton Font-Size="X-Small" CausesValidation="false" Value="column">
                         <ItemTemplate>
                         <table>
                         <tr>
                           <td align="right" valign="top">
                 <telerik:RadComboBox ID="RadComboBoxAddColumns" Height="20px" runat="server" EmptyMessage="Add Columns" HighlightTemplatedItems="True" AllowCustomText="True" Width="150px"
                                Skin="Windows7" >
                            <ItemTemplate>
                                <div>
                                    <asp:CheckBox runat="server" ID="chk1" Checked="false" Font-Size="X-Small"/><%# Eval("COLUMN_NAME") %>
                                </div>
                            </ItemTemplate>
                            <FooterTemplate>
                            <div>
                                <asp:Button ID="btnAdd" runat="server" Text="Add" CssClass="button" OnClick="btnAdd_Click"/>   <asp:Button ID="btnReset" runat="server" Text="Reset" CssClass="button"
                                            OnClick="btnReset_Click"/>
                            </div>
                            </FooterTemplate>
                  </telerik:RadComboBox>
            </td>
            </tr></table>
                         </ItemTemplate>
                        </telerik:RadToolBarButton>

And I need to map the code behind click event for each button, I can get reference of the button:

Button btnAdd = (Button)RadToolBar1.FindItemByValue("column").FindControl("RadComboBoxAddColumns").FindControl("btnAdd");

But how do I know which button is clicked? Please help!

Thanks a lot!

I got it work right, the button click can automatically map to the right button.
