Hello Fabiana,

These problems occur when the grid is placed in a control that measures its children with infinity.  Such controls are ScrollViewer,  StackPanel (when vertical it measures with infinite height and when horizontal - with infinite width), and Grid panel with RowDefinition Height="Auto" or ColumnDefinition Width="Auto". When RadGridView (or any other grid) is measured with infinity virtualization is turned off which results in reduced performance. Modify your code so that RadGridView is placed in a container that will not measure it with infinity and the performance will be back to normal.
