How to wire a button click event in a composite control?

[Russ]

I just can't seem to do it. In my composite control I add a button:

Button Db = new Button ();
Db.ID = "DedButton" + i;
Db.Style.Add ("Position", "Absolute");
Db.Style.Add ("Left", "300px");
Db.Style.Add ("Top", "290px");
Db.Text = "Edit Deductions";
Db.Click += new System.EventHandler(DedButton_Click);
pv.Controls.Add (Db);

(pv is a pageview control)

Then in the same class I have:

private void DedButton_Click (object sender, System.EventArgs e)
{

}

I put a breakpoint at the entry point of DedButton_Click, but it never
gets there. Clicking the button does cause post back, but the event
never fires. I have had the same problem with the OnChange event for
a Drop Down List. I gave up on the DDL and am now trying to make a
simple button work.

HALP!

Thanks, Russ

Does your composite control re-create the button on postback?
If not, it can not handle events, because it's not there anymore.

THANK YOU Jos ! You probably can't imagine the amount of time I have
spent trying to get some form of this working. Yes, I was recreating
it on postback. But when you asked, I thought about the fact that I
do not add the event handler when I recreate it. I didn't think I
needed it because I don't display the window again after the event is
handled.

Whew! Now I can get on with the job.

Thanks again Jos.
