Hello Support,

We are using RadListView and RadDataGrid controls in our UWP and iOS applications. On these controls we observed there is a lag when we scroll fast, this lag is with the control's default scroll  Please see attached video (UWP_without_scrollview.mp4 and iOS_without_scrollview.mp4) for our UWP and iOS applications, you will see the white space when scrolling very fast.   

Further, we tried adding Xamarin's ScrollView over the RadListView and RadDataGrid controls, with this we do not see the lag when scrolling fast (see attached video UWP_with_scrollview.mp4 and iOS_with_scrollview.mp4).

In the documention for the RadListView and RadDataGrid controls, (refernce https://docs.telerik.com/devtools/xamarin/controls/listview/listview-getting-started#:~:text=Telerik.XamarinForms.DataControls%22-,WARNING,-%3A%20RadListView%20control%20provides), it is mentioned that if we add Scrollview to these controls, it would have issue withe the UI Virtulization or Gesture Mechanism. Kindly let us know if can continue using Xamarian ScrollView with the RadListView and RadDataGrid controls?

Also please let us know if there is any other way to get around the lagging issue with using the the RadListView and RadDataGrid default Scroll.
