ENTER key as TAB in datagridview issue in vb.net

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
Its perfectly working, but when I am in the last row, I need to press
ENTER key two times before it move to another column, If I do not edit a
cell, It will move when I press ENTER key once, but if I edited a cell and
then press ENTER key, I need to press it twice.
Thank you for your help
