Question

In order to initialize my VouchersDGV Data Grid View I’m Using the following

 DGV.AllowUserToDeleteRows = True
 For i = 1 To DGV.RowCount - 1
     DGV.Rows.Remove(DGV.Rows(i - 1))
     DGV.Refresh()
 Next

But when I’m runing it for the first time I take the error of

{“Uncommitted new row cannot be deleted.”} System.InvalidOperationException

If I will continue and run my code and write a new row in my Data Grid and I will try to initialize again (now I have two rows, one has the data and the other is empty) I take this error

{“Uncommitted new row cannot be deleted.”} System.InvalidOperationException

I can’t solve it, Please is there someone to assist me on that?

Answer 1

If Not DGV.Rows(i).IsNewRow Then
    DGV.Rows.RemoveAt(i)
End If

Add this condition to your loop. Alternatively, you could also use DGV.RejectChanges() which will reset all the row status to original.
