Click event for calendar management

I have added a click event to control the calendar. But with my implementation this event doesn't work.

My code in Cal.cs control:

#region click
public static RoutedEvent ClickEvent =
EventManager.RegisterRoutedEvent("Click", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(Cal));

public event RoutedEventHandler Click
{
    add { AddHandler(ClickEvent, value); }
    remove { RemoveHandler(ClickEvent, value); }
}

protected virtual void OnClick()
{
    RoutedEventArgs args = new RoutedEventArgs(ClickEvent, this);
    RaiseEvent(args);
}

protected override void OnMouseLeftButtonUp(MouseButtonEventArgs e)
{
    base.OnMouseLeftButtonUp(e);
    OnClick();
}
#endregion

      

        
        
        
      

    

XAML code:

<Calen:Cal x:Name="Calendar" Margin="0,50,0,0" Click="Calendar_Click"/>

      

        
        
        
      

    

C # code:

private void Calendar_Click(object sender, RoutedEventArgs e)
{
    string t = "";
}

      

        
        
        
      

    

I haven't found any solution. I don't know why this code is not working correctly.

Can you help me with this problem?
