NullReferenceException in designer
posted

Hi. I have a XamZoombar in my charting app and it appears to be causing a NullReferenceException at design time. Stack trace is below. My ZB contains a secondary chart as its HorizontalPreviewContent. The ZB Range is bound to my primary chart (xamDataChart1) as follows. If I remove this binding the designer loads correctly:

Range="{Binding ElementName=xamDataChart1, Path=HorizontalZoombar.Range, Mode=TwoWay}"

Regards

    For anyone interested, I was using the eval version of IG WPF. I've upgraded to the paid version and this issue is fixed.
