Need help on dynamically loading ASP user control

[qgma58]

I am writing an internet app using ASP.NET. I created a Web Usercontrol and added some server controls to it. One of the control is a submit button. I have added the event handler correctly. If I drop the control on a Webform in design time, it works fine. If I add the control dynamically to the form by use of a placeholder control, the event is not fired. Does any body know what else I need to do to get the event fired?

Any help will be appreciateed

You have to add the handler dynamically too.

I have added the handler in the control. The code is in the below:
(This is the code in the comster control.

protected override void CreateChildControls()
{
txtMath = new TextBox();
txtMath.TextMode = TextBoxMode.MultiLine;
Controls.Add(txtMath);
// Start a new line
Controls.Add(new LiteralControl("<br>"));
// Set the Text property and add the Button control.
btnSum = new Button();
btnSum.Text = "Sum";
Controls.Add(btnSum);
// Add Label and Literals to display result.
lblResult = new Label();
Controls.Add(lblResult);
Controls.Add(new LiteralControl("</b>"));

btnSum.Click += new EventHandler(butSumClicked);

}

private void butSumClicked(object sender, EventArgs e)
{
// Call the Sum method.
DoSum();
}

When you dynamically add the usercontrol are you declaring it "WithEvents"?
