The project illustrates how to bubble an event from Web User Control to the web page that may display something on Web Page according to which event is fired in this User control. To achieve that, we declare a delagate and an event in the user control code behind, add one button to this User Control.  Add the following lines of code in the click event of button of User Control.

if (MyEvent != null)
{
    this.MyEvent(sender, e);
}
Response.Write("User Control��s Button Click <BR/>");

In the Default.aspx.cs file,Load the usercontrol, and subscribe the event of the user control in the page load event.  Define a suitable event handler to display the dropdownlist selected value.
