Style loss after upgrading to WPF 2010 SP2

[Gili Korman Golander]

Hello,

Recently we have upgraded our Telerik dlls to 2010 SP2  (had the 2010 Q1 before).
We found that some of our custom style templates for the RadGridView are no longer applied for some reason.
For example, our GridViewPanel style, our GridViewFooter style etc.

Please note - we are using implicit styles (no x:Key on the style, just TargetType).
How should we fix this? I saw you had mentioned that " All RadControls skins now get a major facelift. Your custom themes might not work as expected" - but this is rather vague and does not allow me to find out why the styles aren't applied now or how should I fix this.

To make things worse, after the Telerik upgrade, Blend does not open the solution anymore, neither does it give me any error messages.

I'd appreciate some help, Tx.
Gili

Hi Gili Korman Golander,

This is strange and unexpected behavior. Could you please send me a sample reproducing this error so I can have a look at it and be of assistance?

All the best,

Hello,

I am posting a sample window xaml where I have implicit styles for the grid and group panel. The grid style is applied, but the group panel style does not get applied with the Telerik 2010 Q1 SP 2 dlls. It used to work in the 2010 Q1 release. Please comment on the change in the Telerik style mechanism and what is the best way to handle this.

Also, we would appreciate if you would advise clients on breaking changes in styles in the future - it seems to happen with every Telerik upgrade and we are at a loss trying to figure out what went wrong.
