How to create user define (new) event for user control in WPF ?one small example

by

A brief example on how to expose an event from the UserControl that the main window can register:

In your UserControl:

1 . Add the following declaration: 

public event EventHandler UserControlClicked;

2 . In your UserControl_Clicked event raise the event like this: 

 private void UserControl_MouseDown(object sender, MouseButtonEventArgs e)
 {
        if (UserControlClicked != null)
        {
            UserControlClicked(this, EventArgs.Empty);
        }
  }

In your MainWindow:

Your usercontrol will now have a UserControlClicked event which you can register to:

<local:UserControl1 x:Name="UC" UserControlClicked="UC_OnUserControlClicked" />
