Not directly no. But its simple enough to set a Session variable so that
it will know.

How would that help the OP though - Page_Load event fires before OnClick
event (which I would guess is where you would set the session value).

does server-side page_load [know] what button was pressed on a postback?

Yes - Request.Form["__EVENTTARGET"]

However, it has no need to know this...

Here's the reason i ask:

i have an UpdatePanel that contains a div which contains my web user control
called CalendarHelper.ascx. The user control consists of a textbox, calendar
image button, and calendar to help with date entry. I can load this user
control dynamically but whenever i click the calendar icon to make the
calendar appear the webcontrol just disappears on postback/async callback.

This is the only code i have and thought i would need:

protected void BtnEdit_Click(object sender, EventArgs e)
{
CalendarHelper cal1 = new CalendarHelper();
cal1 = (CalendarHelper)cal1.LoadControl("CalendarHelper.ascx");

divmain.Controls.Add(cal1);
}

p.s. i know there is an easier way to do this but i have to work with the
user control that i've been given.

What code is behind the calendar icon?

all that does is toggle the calendar control's visibility.

You need to reload the ascx in the page init event.
