[Solved] RadChart - Theme Drill Down in a Single Chart Area

[Jonathan]

Hello - 

I am having issues applying a theme to a Silverlight RadChart that uses Drill Down logic in a single chart area. I created a sample project based on the exact source code found here (http://www.telerik.com/help/silverlight/radchart-features-drill-down-in-a-single-chart-area.html). When I issue a StyleManager.SetTheme call to any theme other than Office_BlackTheme a blank page is rendered in the browser Is there something I am missing?

Thanks -

            radChart.ItemsSource = GetChartData();
            //this does not work. Setting to any other skin besides Office_BlackTheme
            //causes the page to not render
            //A blank page is displayed in the browser
            StyleManager.SetTheme(radChart, new VistaTheme());

            //this is the only theme that works

Hello Jonathan,

You need to explicitly reference the theme assembly as only the default theme (Office_Black) is embedded in the control assembly in order to limit the assembly size. So if you want to use the Vista theme for example,  you need to reference the Telerik.Windows.Themes.Vista.dll that is available as part of the suite installation.

Hope this helps.

Perfect, worked great after adding those references. Thanks.
