ENTER key as TAB in datagridview issue in vb.net

Here is my working code of pressing Enter key to move to another cell like TAB:

Private Sub dvFromAlloc_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles dvFromAlloc.KeyDown
    If e.KeyCode = Keys.Enter Then

        Dim colm As Integer = dvFromAlloc.ColumnCount - 1
        Dim row As Integer = dvFromAlloc.RowCount - 1
        Dim currCell As DataGridViewCell = dvFromAlloc.CurrentCell

        If currCell.ColumnIndex = colm Then
            If currCell.RowIndex < row Then
                'gets the next row and the first selected index
                dvFromAlloc.CurrentCell = dvFromAlloc.Item(0, currCell.RowIndex + 1)
            End If
        Else
            'move in next col in the current row
            dvFromAlloc.CurrentCell = dvFromAlloc.Item(currCell.ColumnIndex + 1,  currCell.RowIndex)
        End If

        e.Handled = True
    End If

End Sub

Private Sub dvFromAlloc_CellEndEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dvFromAlloc.CellEndEdit
    isEdited = True
    iColumnindex = e.ColumnIndex
    irowindex = e.RowIndex
End Sub

Private Sub dvFromAlloc_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles dvFromAlloc.SelectionChanged
    If isEdited Then
        isEdited = False
        dvFromAlloc.CurrentCell = dvFromAlloc.Item(iColumnindex + 1, irowindex)
    End If
End Sub

The main problem here is that when I'm in the last row, I have to press enter twice after editing a cell before it moves to another cell, but if I'm in the other rows, I will only press enter once after editing the cell and it will move to the next cell.

Thank you for your help

This is my edited code in the CellandEdit and SelectionChanged:

Private Sub dvFromAlloc_CellEndEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dvFromAlloc.CellEndEdit
    isEdited = True
    iColumnindex = e.ColumnIndex
    irowindex = e.RowIndex

    If dvFromAlloc.CurrentRow.Index = dvFromAlloc.RowCount - 1 Then
        If dvFromAlloc.CurrentCell.ColumnIndex < dvFromAlloc.ColumnCount - 1 Then
            dvFromAlloc.CurrentCell = dvFromAlloc.Item(iColumnindex + 1, irowindex)
        End If
        isEdited = False
    End If

End Sub

In the code above(CellEndEdit), I have a first If statement: If the current row index is equals to the row count(that means I am checking if I am in the last rows) then I will execute the second If statement.

The second If statement: if the current column index is less than the column count, then I will move the current cell to the next cell.

Private Sub dvFromAlloc_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles dvFromAlloc.SelectionChanged

    If isEdited Then
        If dvFromAlloc.CurrentCell.ColumnIndex < dvFromAlloc.ColumnCount - 1 Then
            dvFromAlloc.CurrentCell = dvFromAlloc.Item(iColumnindex + 1, irowindex)
        Else
            dvFromAlloc.CurrentCell = dvFromAlloc.Item(1, irowindex + 1)
        End If
        isEdited = False

    End If

In the code above(SelectionChanged), I have put an If else statement: If the current cell column index is less than the column count, then I will move to the next cell until I reach the last column. Elseif I am in the last column, then I set the current cell to the column index 1 and increment the row index to 1 so that it will move to the next row.

And also I change the properties of my DGV of the EditMode to:EditonKeystrokeOrF2

This code is perfectly working for me, I do not change code in the keydown event.
