Hello, 

I have a rather large project that uses Rad Controls for Silverlight 2013 Q1 with a significantly modified version of the Windows8 theme.

I would like to upgrade to Q2 but am worried about how the custom theme will affect the upgrade.  

Is there a recommended approach for doing this other than going through the tedious comparison of the theme's xaml files?  It may not be that big an issue for this particular upgrade, but as future upgrades are released I presume the built in theme will move further and further away from my custom theme based on 2013 Q1.

Thanks

Doug

Hello Doug,

Generally, it is not very easy to support having a custom theme every time when you upgrade to a newer version. We do not have rules on how to do that either.

What I would suggest you is to use Implicit Styles instead. You can check our online documentation for more information on them.
