Server side event for asp control within itemtemplate

[Brad H]

I have a radMenu with an ItemTemplate in it.  Within that ItemTemplate, I have an asp textbox and  imagebutton comprising a search feature.  How can I get a server side event to fire when that imagebutton is clicked?  I can't seem to access it.  I understand how to access and change properties of controls within ItemTemplate.  But I cannot figure out how to get an event handler.  Here is my code.  Thanks for your help!

<telerik:RadMenu ID="trmNavSearch" runat="server" Skin="NavSearch" EnableEmbeddedSkins="false"
        EnableEmbeddedBaseStylesheet="false">
        <Items>
            <telerik:RadMenuItem runat="server" Width="164px">
                <ItemTemplate>
                            <asp:TextBox ID="tbSearch" ValidationGroup="vgSearch" MaxLength="100"
                                runat="server" CssClass="textbox"></asp:TextBox>
                            <asp:ImageButton ValidationGroup="vgSearch" ID="btnSearch" runat="server"
                                ImageUrl="~/global/images/green_arrow_submit.png" />
                </ItemTemplate>
            </telerik:RadMenuItem>
        </Items>
    </telerik:RadMenu>

This code behind obviously does not work as "btnSearch" is not recognized in the handler.

Protected Sub btnSearch_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSearch.Click
        Dim myURL As String = ""
        myURL = myURL & "Search.aspx?SearchTerm=" & trmNavSearch.FindItemByText("tbSearch").Text.Trim & "&I="
        Response.Redirect(myURL.ToString)
    End Sub

Nevermind.  I found the answer.  I just needed to assign the Sub in the OnClick property.  Thanks anyway.

<asp:ImageButton ValidationGroup="vgSearch" ID="btnSearch" runat="server"
                                ImageUrl="~/global/images/green_arrow_submit.png" OnClick="btnSearch_Click"/>
