Horizontal bar memory leak

[Greg Mulert]

Hi, we're using the Q3 2010 RadChart in horizontal bar mode to display a dashboard gadget. The ItemsSource is bound in XAML to an ObservableCollection that gets updated every 30 seconds. With every rebind there's a memory leak that eventually crashes the browser. It's only the horizontal bar (or horizontal stacked bar) -- switching it to a pie or a vertical bar fixes the problem. We're not doing anything fancy; here's the XAML (the DataContext is an object whose TheData property gets updated on the 30 second interval).

<telerik:RadChart BorderThickness="0" ItemsSource="{Binding TheData}">
    <telerik:RadChart.DefaultView>
        <chart:ChartDefaultView>
            <chart:ChartDefaultView.ChartLegend>
                <chart:ChartLegend Visibility="Collapsed" />
            </chart:ChartDefaultView.ChartLegend>
            <chart:ChartDefaultView.ChartArea>
                <chart:ChartArea EnableAnimations="False" SmartLabelsEnabled="False"/>
            </chart:ChartDefaultView.ChartArea>
</chart:ChartDefaultView>

    </telerik:RadChart.DefaultView>

    <telerik:RadChart.SeriesMappings >

        <telerik:SeriesMapping>

            <telerik:SeriesMapping.SeriesDefinition>

                <telerik:HorizontalBarSeriesDefinition />

            </telerik:SeriesMapping.SeriesDefinition>

            <telerik:SeriesMapping.ItemMappings>

                <telerik:ItemMapping DataPointMember="XCategory" FieldName="Status"/>

                <telerik:ItemMapping DataPointMember="YValue" FieldName="Count"/>

            </telerik:SeriesMapping.ItemMappings>

        </telerik:SeriesMapping>

    </telerik:RadChart.SeriesMappings>

</telerik:RadChart>
