Hi,
is there a way to disable the virtualization?
I need to perform calculations on rows that don't exist in the virtualizing panel.

Thanks,
Tal

Hello Tal,

The current official release does not allow that. We have modified the virtualization logic, so that it will realize all rows when placing the grid in a container with a Height of infinity to match the default behavior in other WPF controls. Starting with Q1 2009, which is to ship in a couple of days, you will be able to wrap the RadGridView in a StackPanel, and put that in a ScrollViewer control and achieve the behavior you desire.

On a side note, I am not really sure you should be performing calculations on your visual objects. I am speaking without much context, but your requirement looks like a prime candidate for a view model implementation that would do the calculations, expose the calculated values through public properties, and have your UI bind to those properties. More details on the Model-View-ViewModel pattern are available here.

Kind regards,
