Hi,

I have the following code:

void buttonClick(object sender, EventArgs e)

{

Button bn = sender as Button;

if (bn.Name == “button1”)

{

MessageBox.Show(“Hey its button one”);

}

}

I am interested in the object sender and eventargs e

From what I understand the object is the object that is raising the event, which is a button in this case. I can use the event as an entry point for several objects (again all buttons) and then I can test to see which button was clicked. I have done this in this code.

A couple of questions:

1. Is there anything else I would commonly use the object for?

2. I am unclear on what if anything I can do with the eventargs or ‘e’

Thank you for any help or pointers with this.
