Weird behavior when scrolling a grid that uses an Expendo object.

[Sébastien]

Hi,

My DataGrid uses an Expando object. When pressing and holding the keydown or keyup, the grid behaves incorrectly. I tried to set the RowHeight to see if it would help, but no.

The scroll viewer is kind of reset and for each reset, the offset is getting smaller and at some point, it stops doing the bug.

I tested the behavior with a previous project (few years old) and I can repro the bug! (see video)

Hi Sebastien,

Thank you for the provided files.

The RadDataGrid does not have a support for expand objects. We have such request for Telerik Xamarin DataGrid: https://feedback.telerik.com/xamarin/1366439-datagrid-add-support-for-visualization-of-dynamic-type-of-data 
Both controls UI for UWP DataGrid and Xamarin DataGrid use the same data engine and expando object/dynamic objects are not supported.
