Hi there,

Recently i needed to update my version of Telerik.
I have a template for Expander and it always work with 2011.1.427.1040. But now, with 2012.1.215.1050, it doesn´t work anymore.

{

xaml = streamReader.ReadToEnd();

}

ResourceDictionary rd = XamlReader.Load(xaml) as ResourceDictionary;

expander.Style = (Style)rd["RadExpanderStyle"];

Do I have to define again all template?
There is a way to find the error without writing a new resource?

Thanks!!

Hi Tarcisis,

I think I am successfully using your custom Style. Please check out the attched SL 5 project, it uses 2012.1.215.1050 and correct me if I am missing something. Thank you in advance.

Hi Petar ,

Thanks for the reply.
I tried the sample you send but still not working!
I can´t see the content of RadExpander, so i don´t know if expander really works!
And Im sure im using 2012.1.215.1050 .
Do i need to change anything?

Best regards,

Tarcisis

Hi Tarcisis,

In 2011, we introduced some changes in the default Style/Template of the RadExpander. I used the new Style and applied your custom changes over it. You can see this in the attached project. I hope this resolves your issue.
