Default The control that triggered the UpdatePanel control

Hi All,
On my page, I have a custom control in which asp server controls can be added and a UpdatePanel to notify the server of any edit in progress in the custom control...I would like to know which server control triggered the postback whitin my custom control. Currently, my customControl is declared as follow:
            <daf:UpdateInProgressPanel ID="UpdateInProgressPanel1" runat="server" DisabledStateControlId="Button1" OnUpdateOccured="UpdateInProgressPanel1_UpdateOccu red">

and the following events will trigger a postback:

        document.onchange = handleEvent;
        interceptor.onclick = handleEvent;
        interceptor.onkeypress = handleEvent;
        interceptor.onkeydown = handleEvent;
        interceptor.onpaste = handleEvent;

My problem is that after postback, I would like to set the focus on the control which triggered the post back. So far, I have used the following:
string ctrlname = page.Request.Params.Get("__EVENTTARGET");
if (((ScriptManager)this.Page.FindControl("ScriptMana ger1")).IsInAsyncPostBack)
                fromWhere = this.Page.Request[((ScriptManager)this.Page.FindControl("ScriptManag er1")).ID];
in order to get the control but i am always getting the custom control. I want to associated postback events to the custom control only but would like to know which control within it originated the postback...

Any help will be appreciated.
