We are using the grid in a TabControl, using Virtualize for RecordContainerGenerationMode. In this mode, tab switching is quite slow -- up to 2 seconds. We noticed the same problem on the latest Feature Browser sample (go to xamDataGrid -> Data Binding and Interaction -> SQL Data Binding, and click back and forth between the "Sample" and "XAML" tabs).
When we switch to LazyLoad, the tab switch performance is improved, but memory usage is higher when scrolling, and there is still a delay before you can interact with the grid.
Is there a way to get the benefits of Virtualize mode when using the grid in a tab control? We also tried switching between LazyLoad and Virtualize when tab switching, but were not sure if this was recommended.
