GridView Click Event Not Firing

[ADN]

Hi,

I am currently extending the GridView control and would like to add a
button to the GridView so that it will automatically render one
button
at the top of the grid. I have a click event for that button, but
everytime the button is clicked, the page posts back and the click
event does not fire (probably because the button gets created every
single time there's a postback). What is the best way for me to
create
this button and then make the click event fire?


I would like it so that I can drag my custom GridView onto an .aspx
page and not have to worry about handling any events on that page so
that it is all handled by my gridview. Is that even possible?

public class MyGridView : GridView
{
Button btnMyButton;


protected override void OnInit(EventArg s e)
{
btnMyButton = new Button();
btnMyButton.ID = "btnMyButto n";
btnMyButton.Tex t = "Click Here";
btnMyButton.Ena bleViewState = true;
btnMyButton.Cli ck += new
System.EventHan dler(MyGridView _MyButtonClick) ;
base.OnInit(e);
}


protected override void Render(HtmlText Writer __writer)
{
btnMyButton.Ren derControl(__wr iter);
base.Render(__w riter);
}


public void MyGridView_MyBu ttonClick(objec t sender, EventArgs
e)
{
//=== Button Click Event code goes here....
}
}

RE: GridView Click Event Not Firing

you never add the button to the page control collection, so there is no way
for the event framework to find it, and tell it to fire the event. you should
add to the page control collection (or as a child of a control in the
collection) in the oninit or createchildcont rols.
