Exception after Styling RadChart

[Ruhban]

Hi,

I am trying to style a RadChart. It is a bargraph (set from code) and I want to change the default colors of the bars. So I used the RadChart.PaletteBrushes and defined SolidBrush colors(Found this method in the following link : http://www.telerik.com/help/wpf/radchart-styling-and-appearance-styling-chart-series.html) as follows:

<telerik:RadChart Background="Transparent" HorizontalContentAlignment="Center" HorizontalAlignment="center"> 
       <telerik:RadChart.PaletteBrushes> 
                <SolidColorBrush Color="#FF0B3F74"/>  
                <SolidColorBrush Color="#FF721111"/>  
                <SolidColorBrush Color="#FFA1720B"/>  
      </telerik:RadChart.PaletteBrushes> 
</telerik:RadChart>

But now, an exception as follows occurs while running the application :

'System.Windows.Media.SolidColorBrush' must have IsFrozen set to false to modify.

This exception occurs randomly. Also, in the stack trace, there is a mention of RadTransition Control too. Why could this error be occuring? How can it be solved?

Hello Vishal,

Can you please give us some more details about your scenario? The best option is to send us a small runnable project with the error because our developers cannot reproduce it with our local tests.

Thank you in advance,

Hi,

As the error occurs randomly, I am unable to provide you with a sample project which would show this error. I could provide you the Exception Message, which is as follows. Hope this can help you to suggest a solution for this issue.

System.Windows.Markup.XamlParseException: Specified value of type 'System.Windows.Media.SolidColorBrush' must have IsFrozen set to false to modify. ---> System.InvalidOperationException: Specified value of type 'System.Windows.Media.SolidColorBrush' must have IsFrozen set to false to modify.

Hello Vishal,

Unfortunately we are unable to reproduce the problematic behavior locally and we have not received similar reports so far. Could you send us a runnable sample application or some guidelines for your specific scenario that would allow us to observe the erroneous issue and advise you properly how to proceed.

Looking forward to your reply.

Kind regards,
Sia

Hi!
Although I'm not using the telerik controls, I'm currently facing almost the same problem.
I'm building an application with lots of ResourceDictionarys and styles used by many different and nested views and user controls.

Seems that this link describes the issue very well. Hope that Microsoft will provide a solution for that.
