Windows 7 theme problem with Silverlight 5

[Krasimir]

Hello Telerik team,
I've just upgraded my application to Silverlight 5, but I have this error with Windows 7 theme. The problem doesn't occure with any of the other themes.

Hello Krasimir,

The experienced issue is due to some changes in the styling mechanism in the latest version of the control. When creating the chart instance in code-behind you would need to move the configuration code to the RadChart.Loaded event handler.

RadChart chart = new RadChart();
chart.Loaded += (sender, args) =>
{
    ....
   chart.DefaultView.ChartArea.DataSeries.Add(series);
};

Please excuse us for the inconvenience caused and let us know whether this solves your problem.

Greetings,

Thank you Sia,
Unfortunately this doesn't help me. I'm binding the series in xaml or in loaded event and neither works. Actually the silverlight doesn't reach to the xaml at all. It breaks up in App.xaml.cs file in Application_UserLoaded event.

Hello Krasimir,

This is quite odd as databound scenarios should not require additional changes related to the theming changes introduced in Q3 2011.

Could you open a formal support ticket and send us a runnable sample application that we can investigate locally so we can advise you properly how to proceed (the attached application works here with instance/application theme applied).


Greetings,
Giuseppe
