eventhandlers for dynamically added controls

[Kasper Birch Olsen]

Hi NG

Im adding a bunch of linkbuttons to a page, in a for loop, but I cant get
the eventhandlers to work.

A simplyfied version of the code looks like this:

for (int i = 0; i<10; i++)
{
Button b = new Button();

b.Text = "button_"+i ;

b.Click +=new EventHandler(b_ Click);

buttons[i] = b;

i++;

TableCell tc = new TableCell();

tc.Controls.Add (b);

TableRow tr = new TableRow();

tr.Cells.Add(tc );

this.Table1.Row s.Add(tr);

}

And the b_Click method is defined like:
protected void b_Click(object sender, EventArgs e)

{

throw new Exception("Some one clicked one of the buttons");

}
The code is by memory, never mind syntax issues.

The code looks fine to me, but when the buttons are clicked the page just
reloads, the exception is never thrown, thus i figure the eventhandler
doesnt work.

Any surgestions?

The controls and their event handler need to be created and hooked on
postback - no later than the page_load event.
