Please create a new WPF application project, add reference to ZoomPanel and copy and paste the xaml and cs code from the previous post (http://forum.wpf-graphics.com/showthread...441#pid441). Now replace Page into Window and start the project.

The sample shows that the SetZoom method works and that the title of this thread is not correct.

I do not know what changes you did to your code so I cannot say what could be wrong.
