Hi all,
I have problem........ I have array of buttons and I want to call one
common event service. But I need to know the index of clicked button -- how
can I do that?

thanks

Ok, I knew there was an easier (less code) way to do this...

Basically create your handler function like so:

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

MessageBox.Show(sender.ToString());

}





Then, For each button you can select the Events in the Properties box and
change the Click event to point to your ButtonHandler function.

Hi,

You can use the sender parameter of the handler to see what control sent
the event, if you have your controls in an array it would be something like:

protected void handler( object o, EventArgs e ){

int index = 0;
foreach( Control control in controlArray)
{
if ( sender == control )
break;
index++;
}
}



hope this help,

Click to expand...

The button itself is being passed as "sender," but if you really need it's
index you can save it in buttons "Tag" property.
