I create an RadChart in the code and i want to export it to a file "png".
I disabled animations!

Now the point is in PieSeriesDefinition & LineSeriesDefinition this is correctly working, but in the BarSeriesDefinition & StackedBarDefinition is painting everything except of the bars!

See screenshots..

Any clue why this could occur? I think the BarSeries has some additional Animations?

Hello Felix,

Indeed currently there is a problem with the print/export bar series type in this scenario and you will need to apply this custom bar style manually, which explicitly sets the Opacity to 1:
<Style x:Key="PrintStyle" TargetType="telerik:Bar">
    <Setter Property="Template" >
        <Setter.Value>
            <ControlTemplate TargetType="telerik:Bar">
                <Canvas Opacity="1" x:Name="PART_MainContainer">
                    <Rectangle x:Name="PART_DefiningGeometry"                                  
                                Height="{TemplateBinding ItemActualHeight}"
                                Width="{TemplateBinding ItemActualWidth}"
                                Style="{TemplateBinding ItemStyle}"
                                RadiusX="{StaticResource BarRadiusX}"
                                RadiusY="{StaticResource BarRadiusY}" />
                    <Rectangle Height="{TemplateBinding ItemActualHeight}"
                                Width="{TemplateBinding ItemActualWidth}"
                                RadiusX="{StaticResource BarMaskRadius}"
                                RadiusY="{StaticResource BarMaskRadius}"
                                OpacityMask="{StaticResource BarOpacityMaskBrush}"
                                Fill="{StaticResource BarMaskBrush}"
                                Stroke="{StaticResource BarMaskStroke}"
                                StrokeThickness="{StaticResource BarMaskStrokeThickness}" />
                    <Rectangle x:Name="PART_SelectedState"
                                Height="{TemplateBinding ItemActualHeight}"
                                Width="{TemplateBinding ItemActualWidth}"
                                RadiusX="{StaticResource BarRadiusX}"
                                RadiusY="{StaticResource BarRadiusY}"
                                Fill="{StaticResource BarTopMaskBrush}" />
                </Canvas>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Hope this helps.

Kind regards,

Hello Felix,

You only need to apply the aforementioned style to the bar series. Please, find attached a sample application demonstrating this.

Hi Felix,

Our developers are aware of this issue, however, we cannot commit to a concrete time frame for the implementation of the fix and for the time being we would recommend using the available workaround.

We would also highly recommend our new ChartView control for scenarios as this one, as it addresses some of the shortcomings of RadChart and has other various improvements.

Kind regards,
