Can parent control detect child controls events?I mean for example i have panel with many buttons in it and instead of adding click event handler to every button can i handle their click events in different manner?I just want to know which button exatcly is pressed.Can i do it without adding event handlers for every button?

Yes and yes. A button control has a click event. The ide usually handles the details, but you can certainly do them on your own. Here's an example:

CODE

public form1() {

   InitializeComponent();
   this.button1.Click += new System.EventHandler(this.myClickHandler);

   this.button2.Click += new System.EventHandler(this.myClickHandler);
   this.button3.Click += new System.EventHandler(this.myClickHandler);
}


private void myClickHandler(object sender, System.EventArgs e) {
   Button button = (Button)sender;
   if (button==this.button1) {
   } else if (button==this.button2) {
...


Hope this helps.
