Getting control name for an event

Question

In my C# Windows Forms form I have some buttons which are dynamically generated. I assigned the following method on the click event. Is it possible to get the name of the bu

Answer 1

The first argument of the event handler, "object sender", contains a reference of an object/control which raised/fired an event.

var button = sender as Button;

Answer 2

You can use the sender argument. That is the Control (the button in this case) that has raised the click event:

var button = (Button)sender;
button.Name ...

N.B.: In case you have subscribed other controls (e.g. panels, etc.) to the same event handler, you can check if the sender is a button using the asoperator:

var button = sender as Button;
if (button != null)
{
    button.Name ...
    ...
}
