How do you know which control fired the event
Example
Private sub button1_click(byval sender as system.object, byVal e as system.eventargs) handles button1.click
End sub
Passes 2 parameters
First-is called sender (type object)
This is the control that fired the event
By casting it to appropriate object, you can interact with it like any other control
Handles button1.click
This is what connects control to event
You can add several controls to an event :
Private sub button1_click(byval sender as system.object, byVal e as system.eventargs) handles button1.click, button2,click, button2.click
End sub
