Thanks David, but that doesn't seem to work for me.  If I comment the Legend Style below, it shows as expected.  With the style, I see the srollviewer, but nothing inside of it. 

I'm using Infragistics.Silverlight.DataVisualization.Chart.v9.1
Version: 9.1.20091.1000

<igChart:XamWebChart x:Name="XamWebChart1">
    <igChart:XamWebChart.Legend>
        <igChart:Legend>
            <igChart:Legend.Style>
                <Style TargetType="igChart:Legend">
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="igChart:Legend">
                                <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
                                    <ScrollViewer Height="200">
                                        <ContentPresenter Height="300"/>
                                    </ScrollViewer>
                                </Border>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </igChart:Legend.Style>
        </igChart:Legend>               
    </igChart:XamWebChart.Legend>
    <igChart:XamWebChart.Series>
        <igChart:Series ChartType="Column" Label="Series 1">
            <igChart:Series.DataPoints>
                <igChart:DataPoint   Value="10" Label="point1" />
                <igChart:DataPoint   Value="20" Label="point2" />
                <igChart:DataPoint   Value="30" Label="point3"  />
            </igChart:Series.DataPoints>
        </igChart:Series>
        </igChart:XamWebChart.Series>
</igChart:XamWebChart>

Am I missing something?

Thanks,
Keith

whoops, the code i posted was for WPF and there is a slight difference.  you need to change the ContentPresenter to a Canvas named RootElement.

 <igChart:XamWebChart x:Name="XamWebChart1">
            <igChart:XamWebChart.Legend>
                <igChart:Legend>
                    <igChart:Legend.Style>
                        <Style TargetType="igChart:Legend">
                            <Setter Property="Template">
                                <Setter.Value>
                                    <ControlTemplate TargetType="igChart:Legend">
                                        <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
                                            <ScrollViewer Height="200">
                                                <Canvas x:Name="RootElement" Height="300"/>
                                            </ScrollViewer>
                                        </Border>
                                    </ControlTemplate>
                                </Setter.Value>
                            </Setter>
                        </Style>
                    </igChart:Legend.Style>
                </igChart:Legend>
            </igChart:XamWebChart.Legend>
            <igChart:XamWebChart.Series>
                <igChart:Series ChartType="Column" Label="Series 1">
                    <igChart:Series.DataPoints>
                        <igChart:DataPoint   Value="10" Label="point1" />
                        <igChart:DataPoint   Value="20" Label="point2" />
                        <igChart:DataPoint   Value="30" Label="point3"  />
                    </igChart:Series.DataPoints>
                </igChart:Series>
            </igChart:XamWebChart.Series>
        </igChart:XamWebChart>

Could you share more detail as to how you are moving between them? Are they in a tab control or are you removing and adding them to the visual tree? If you could provide a small sample that illustrates the issue that would help. You may need to have the fake canvas refresh when the controls loaded event fires also, depending on what you are doing.

I have used this on one of my applications. In my application I am moving from one chart to another with the click of series of buttons. When I land on the chart that I have included the "FakeCanvas" on the first time it works great. However, when I go from that chart to another chart and then come back, the legend items are totally gone. How do I get the items to build each time?

Thanks

ptilwani,

It's come to my attention Developer Support is helping you with this issue, is there any more assistance you need?

Hi Graham,

Please find the ResourceDictStyle.txt attached which is nothing but a resource dictionary.

 In my Page.Xaml I try applying the declared style to the legend in the following way:

<igChart:XamWebChart.Legend>

<igChart:Legend MaxWidth="100" Style="{StaticResource ScrollableLegend}" />

</igChart:XamWebChart.Legend>

Then I get the following error:

Error: Unhandled Error in Silverlight Application
       Code:2255
       Category:Runtime Error
       Message:AG_E_PARSER_BAD_TYPE
       MethodName:

If I decalre the style in UserControl.Resources everything works fine. Please tell me if you need any more info.

Thanks

For starters, make sure you have the same Xaml namespace declarations in your resource dictionary as in the file you originally had the style defined in. Are there any more details about the error than that? Can you provide a sample the reproduces the problem?
