[RESOLVED] Datagridview: move to column 4 but instead to column 5

I want to move the cursor from column 1 to column 4 but what happened instead the cursor moves to column 5, this happens when I use the enter key event. but run well if I double click.
The following description of the program:
there are 7 columns of code, item description, unit, price, qty, discount, item amount
code when key enter press :

vb.net Code:

Private Sub dg_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles dg.KeyUp
        If e.KeyData = Keys.Enter Then
            Dim cRow As Integer = dg.CurrentCell.RowIndex
            Dim cCol As Integer = dg.CurrentCell.ColumnIndex
 
            Select Case cCol
                Case 0, 1, 2
                    LoadProduct()
                    MoveCell(cRow, 4)
        end select
    end if
end sub

and code when double click at datagridview.

vb.net Code:

Private Sub dg_CellDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dg.CellDoubleClick
        Select Case e.ColumnIndex
            Case 0, 1
                LoadProduct()
                MoveCell(cRow, 4)
        End Select
End Sub

at LoadProduct() method program load form dialog to get product list and then choose one of them.

vb.net Code:

'move cursor to crow & ccol cell
 Sub MoveCell(ByVal crow As Integer, ByVal cCol As Integer)
        If crow <= 0 Then crow = 0
        dg.CurrentCell.Selected = False
 
        dg.Rows(crow).Cells(cCol).Selected = True
        dg.CurrentCell = dg.SelectedCells(0)
        dg.Refresh()
 
    End Sub

I have some ways but still could.

thank you

Like every collection in .NET, DataGridView.Columns is zero-based. The first column is index 0, the fourth column is index 3.

agree, the index of the column in the grid starting from 0.
I want my code to move from column to column qty but what happened instead move the cursor to the column discount

Can you not just do this?

vb.net Code:

myDataGridView.CurrentCell = myDataGridView(desiredColumnIndexOrName, e.RowIndex)
