Context Menu with the Right Mouse Button Events
Introduced in Silverlight 4 are several new events, two of these MouseRightButtonDown and MouseRightButtonUp relate to the right mouse button. With these new events it is now easy to implement a right click context menu.

break;
}
popupMenu.Hide();
}
private void LayoutRoot_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
{
Point p = e.GetPosition(this);
Canvas.SetLeft(popupMenu, p.X);
Canvas.SetTop(popupMenu, p.Y);
popupMenu.Show();
e.Handled = true;
}
private void LayoutRoot_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
popupMenu.Hide();
}
}
}
Here we are using the Liquid Popup Menu control for our context menu. When the MouseRightButtonDown event occurs we work out the X/Y position of the mouse and position/show the context menu.
It is important to set e.Handled = true when we have finished in the event handler in order to ensure Silverlight does not show the default Silverlight Context menu.
