Hi Telerik,

my company bougt several Silverlight licences, We wanted update our application from version 2010Q3 to
2011Q2. It costs us several days to migrate the simples things as Expander, RadWindow etc. Please don't be so
quick make little steps. Improve the product and update the documentation. We don't need quick shots but stable product.

If I may ask you. Improve the probably most use control the GridView. Its so slow if used with rating data (numbers 0 - 5)
shown as stars (Image). We must have 50+ columns and hundreds rows.

Regards,
Ladislav

Hi Ladislav,

Actually, we do put a lot of efforts to make the upgrade to our products as easy and painless as possible. We try to update our documentation, demos and to keep our Changes and Backwards Compatibility sections consistent. 
As for the RadGridView, we introduces some significant performance improvements within our current official release - Q2 2011. Do you experience any problems with it ?
