	private GcZoom _gcZoom1 = new GcZoom();

	public GcZoomEventDemo()
	{
		_gcZoom1.Target = this;
		_gcZoom1.AutoShowControl = true;
		_gcZoom1.ManipulationStarting += _gcZoom1_ManipulationStarting;
	}

	void _gcZoom1_ManipulationStarting(object sender, ZoomManipulationStartingEventArgs e)
	{
		Console.WriteLine(e.TargetControl.ToString());
		Console.WriteLine(e.Position.ToString());

		if (e.TargetControl is TextBox)
		{
			// Pan gesture send to child control, Zoom gesture send to Form
			e.Mode = ZoomManipulationModes.Zoom;
		}
		else if (e.TargetControl is Button)
		{
			// Zoom gesture send to child control, Pan gesture send to Form
			e.Mode = ZoomManipulationModes.Pan;
		}
		else
		{
			// Pan and Zoom gesture send to Form
			e.Mode = ZoomManipulationModes.All;
		}
	}
}
