SeriesAppearanceSettings causing error

[Dave]

Sorry for the duplicate, the server throw an error on Post......

I'm trying to change the fill color on a series and using the SeriesAppearanceSettings throws an error. Is there a trick in changing the fill color?

This is the xaml:

<telerik:StackedBarSeriesDefinition StackGroupName="IssueName" ><br>
  <telerik:StackedBarSeriesDefinition.Appearance><br>
     <telerik:SeriesAppearanceSettings Fill="Brown" /><br>
  </telerik:StackedBarSeriesDefinition.Appearance><br>
</telerik:StackedBarSeriesDefinition><br>

This is the error:
Delegate to an instance method cannot have null 'this'

Hello Dave,

Indeed we were able to reproduce the problematic behavior in our local tests as well -- the fix will be included in the official service pack release that should become public by the end of the week.

Sorry for the temporary inconvenience. We have updated your Telerik points for the report as well.


All the best,
Freddie
the Telerik team

Thanks! You guys are awesome, I got release 812, everything fixed,

[David Brubacher]

So are you saying that just as I implemented the work-around version 812 makes it unnecessary? :-)

Finally I can set Appearance in XAML!
