Retrieve the cause of the event

[witzulu]

Hi

 

I would like to know how to retrieve the cause of a event esp. an onclick event.

 

Say I have a sub that handles 5 different buttons onclick event, I would like to know which of the 5 buttons have been clicked

The sender argument will be the button that was clicked

 

the folowing code will just display hte name of the button clicked - you could use this in a select case statement if you needed to make a decision based on this.

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click, Button1.Click, Button3.Click

	Dim b As Button
	b = DirectCast(sender, Button)
	MessageBox.Show(b.Name)

End Sub
