Dim iColumn = DgvData.CurrentCell.ColumnIndex
Dim iRow = DgvData.CurrentCell.RowIndex

If DgvData.Columns.Count = 3 Then
If iColumn = DgvData.ColumnCount - 1 Then
If iRow < DgvData.RowCount - 1 Then
DgvData.CurrentCell = DgvData(0, iRow + 1)
DgvData.BeginEdit(True)
                End If
            Else
                If iRow < DgvData.RowCount - 1 Then
                    SendKeys.Send("{Up}")
                End If
If DgvData.Rows(iRow).Cells(0).Value.ToString = "" And DgvData.RowCount - 1 = 0 Then
                    DgvData.CurrentCell = DgvData(0, 0)
                    DgvData.BeginEdit(True)

Else
                    DgvData.CurrentCell = DgvData(iColumn + 2, iRow)
                    DgvData.BeginEdit(True)
End if
End if
End if

You are trying to edit the data inside your edit handler. You are not allowed to do that as it will cause the handler to be called again from inside the handler, which will cause the handler to be called ...

can you provide EndEdit handler code

No you need to redesign your handler so that it does not try to start an edit process.

The word you are looking for is "recursion" and it's not allowed in this context.
You can't use "BeginEdit" for the same DGV inside it's EndEdit handler (or any other eidt based handler): that could cause a recursive editing loop that would blow your stack and crash your app.

It's like taking money from an ATM: that causes your bank account total to be reduced. But if there was a "reduced bank account" handler that added a fee for each reduction, the withdrawal would trigger it - and that would add a fee, which would trigger it again, and again, and again, ... until the fees emptied your account, and the bank decided you couldn't have the cash from the ATM to start with.

Think about what you are actually trying to achieve - this is not the right approach!
