I can not repro this issues that I just create the simple DataGrid control.

@alraseensaad Could you upload your project code?

alraseensaad commented 2 months ago

Delay the loading like loading large data and will loading press the windows button + arrow it will throw the exception

If the datagrid load is fast, nothing will happen
