I am using a RadGridView with a bound QueryableCollectionView.

Virtualization is enabled

Anytime I scroll through the grid, memory usage of the application goes up and up and up, and never comes back down, even after forcing calls to GC.Collect().  Am I missing something here or is there some issue with scrolling through a QueryableCollectionView?

Thanks,
Brandon

Hello Brandon,

We are currently not aware of any Memory Leaks when scrolling. May I ask you to download the Latest Internal Build and test with those most recent binaries?

In general I would suggest you to go through the Degraded Performance help article suggesting on how you could improve the performance. 
Then I would suggest you to call the GC like so: 

Still even with this code you cannot be sure when the GC will actually execute.

I figured out the issue.  I had not set GroupRenderMode...and it did not default to Flat, so I set it to Flat and it works much better now.
