New Post: Extended WPF Toolkit Zoombox NullReferenceException

Hi,

This is already fixed in v2.6.

In the meantime, go in file Xceed.Wpf.Toolkit/ZoomBox/ZoomBox.cs, in method "SetScrollBars()" and add the following check at the beginning of this method :

if( _content == null || _verticalScrollBar == null || _horizontalScrollBar == null )
        return;
