syncfusion error: System.InvalidOperationException: Sequence contains no elements

[Stefano]

Hi,

in my application there are three grids displayed on three different tabs.

All grid have edit mode set to Normal; when user save data all works fine.

If I change one of grid so that edit is in batch mode, when user save, got this error:
