[Solved] LegendStyle Not Set from Resource Dictionary

[Jeremy Miller]

I have a resource dictionary with the entry:

<Style x:Key="legendStyle" TargetType="telerikCharting:ChartLegend">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="telerikCharting:ChartLegend">
                    <Grid Visibility="Collapsed" />
                </ControlTemplate>
            </Setter.Value>
        </Setter>
</Style>

In one file.  I reference this file from my App.xaml file like so:

<Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary x:Name="Ventana.Vantage.Silverlight.Res-Colors" Source="/Ventana.Vantage.Silverlight.Res;component/Styles/Colors.xaml"/>
                <ResourceDictionary x:Name="PortletStyles" Source="Portlets/PortletStyles.xaml"></ResourceDictionary>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>

Now in the file where I want to use the style, I have it referenced like this:

<telerik:RadChart x:Name="chart" ItemsSource="{Binding Series.Cells}" Grid.Row="1" Margin="0 5 0 0" BorderThickness="0"
                              Style="{StaticResource SmallFont}" LegendStyle="{StaticResource legendStyle}">

This, seemingly straight-forward solution produces no results as for every chart I have, the legend is visible.  The only way to make this work was to use code-behind, but I'd like to not have to do that.  Is this a Telerik bug (because I don't mind filing it) or some mistake on my part?

Hello Jeremy Miller,

Unfortunately I wasn't able to reproduce this behavior. Using styles from ResourceDictionary successfully styles the RadChart. Here's what I have done:

1. I used your style and put it in a new ResourceDictionary named Dictionary1.xaml placed in the application root folder.
2. I registered the dictionary in App.xaml like this:

3. <Application.Resources>
       <ResourceDictionary>
           <ResourceDictionary.MergedDictionaries>
               <ResourceDictionary Source="Dictionary1.xaml" />
           </ResourceDictionary.MergedDictionaries>
       </ResourceDictionary>
   </Application.Resources>

4. I used the style the same way you did and it was applied.

I have attached a sample application that demonstrates this scenario.

Can you please check if there are any errors in the Output window of VisualStudio and upload a sample application demonstrating your issue so that we can further assist you?
