Index of a Button in an array

Question

Hi.
I have an array of buttons that I fire MouseClick event for them in Form1_Load method.
In Button_MouseClick method, How Can I understand What is the index of button that is pressed?(pressed button is one of aforementioned array members)
Can I change signature of Button_MouseClick event and add an int parameter to end of it as index?
Thanks :-)

Notice that the Button_MouseClick event has both a sender and eventarg. The sender IS the button so you can just examine the properties of the button such as the Name to figure out which button was pressed. If you have an array then map the button name to the array index in a hashtable private void button1_Click( object sender EventArgs e) { MessageBox .Show((sender as Button ).Name); }

Hi You can use OnCommand=btn_Command CausesValidation=false> CommandName =1 where 1 is the index of the button and OnCommand =btn_Command is the event method to call when any button from the array is clicked.
