Hi,

We are using nested RadGridView in our application. 
While it works fine for few number of rows, the browser takes 600MB when there are 700 rows (20 columns) and hence it becomes very slow when the number of rows is large.
I have explicitly tried setting EnableRowVirtualization and EnableColumnVirtualization to True. Still, there seems to be no effect on the memory footprint.

The application is built using Silverlight 3.
Do I need to do anything else to make UI Virtualization work?

Regards,
Naveen

Hello Naveen,

In general I would suggest you going through the Degraded Performance help article suggesting on how you could improve the performance of RadGridView. 

Silverlight 3 is a very old version. I would suggest you consider upgrading to our latest UI for Silverlight with support for Silverlight 5. We have done many improvements related to performance that you could benefit from.
We have also introduced Implicit Styles to gain even more.
