How can I have more the one event on button click?

First click --> one event
Second click --> second event

You could make do with 1 event if you have the client's handler remove
itself and add another handler...

private void OnClick( object sender, ClickEventArgs e )
{
// Do something
myForm.Click -= new ClickEventHandl er( OnClick );
myForm.Click += new ClickEventHandl er( OnSecondClick );
}

private void OnSecondClick( object sender, ClickEventArgs e )
{
// Do something
myForm.Click -= new ClickEventHandl er( OnSecondClick );
myForm.Click += new ClickEventHandl er( OnClick );
}


Or, you could simply create a custom control with 2 events.

Depends on your requirements. It sounds like some kind of state machine you are
after here. The state could be held in a class variable or even in the control
itself - the Tag property comes to mind. Or if a simple toggle is all you need
you can even do something really ugly like:

if (btn.Caption == "On")
{
turn_the_damn_t hing_on();
btn.Caption = "Off";
}
else
{
turn_the_damn_t hing_off();
btn.Caption = "On";
}

Crude but effective,
