Ranges binding

[Bernd]

Hi,

I tried to bind the SfLinearGauge Ranges with no success. Ranges is a public ViewModel property of type LinearRangeCollection which is populated programmatically.

This is a simplified version of what I tried:

<syncfusion:SfLinearGauge>

  <syncfusion:SfLinearGauge.MainScale>

    <syncfusion:LinearScale Minimum="0" Maximum="1000" Ranges="{Binding Ranges}"/>

  </syncfusion:SfLinearGauge.MainScale>

</syncfusion:SfLinearGauge>

public LinearRangeCollection Ranges

{

  get

  {

    return new LinearRangeCollection()

    {

      new LinearRange() { StartValue=0, EndValue=100, RangeStroke=new SolidColorBrush(Colors.Green) },

      new LinearRange() { StartValue=100, EndValue=300, RangeStroke=new SolidColorBrush(Colors.Blue) }

    };

  }

}

I already get a NullReferenceException in the XAML designer:

 bei Syncfusion.UI.Xaml.Gauges.LinearScale.ResetRanges()

   bei Syncfusion.UI.Xaml.Gauges.LinearScale.Refresh()

   bei Syncfusion.UI.Xaml.Gauges.SfLinearGauge.MeasureOverride(Size availableSize)

   bei System.Windows.FrameworkElement.MeasureCore(Size availableSize)

   ...

Is this not supported or am I doing something wrong?

Regards

Bernd
