DataGridView - Setting Focus on a Cell

VB 2010 (Professional)

I'm using an unbound DataGridView for data entry.  The first column is the row number, and will automatically be set when data is first entered in a row.

To that end, I set the first column to ReadOnly.  However, when tabbing from column to column, column 0 still gets focus (nothing can be typed in, though, which is right).  What I would like is for the tabbing to skip over column 0 and go directly to column 1, ready for user input.

So I added code to the CellEnter event as such: 
Private Sub DataGridView1_CellEnter(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellEnter
    If e.ColumnIndex = 0 Then
        'DataGridView1.Rows(e.RowIndex).Cells(1).Selected = True 'Didn't Work
        DataGridView1.CurrentCell = DataGridView1.Item(1, e.RowIndex) 'Didn't Work too
    End If
End Sub

Open in new window

As you can see in the sample code, I tried two different methods, but neither works.  Both throw the error: 
Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.

Open in new window


So, how do I do what I want to do?

You cant do it in this way :
add private variable for example : 

Private cellEnterInUse as boolean=false

Open in new window


and in your sub add one condition :

  
Private Sub DataGridView1_CellEnter(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellEnter
  if not cellEnterInUse Then
   cellEnterInUse=True
    If e.ColumnIndex = 0 Then
        'DataGridView1.Rows(e.RowIndex).Cells(1).Selected = True         
        DataGridView1.CurrentCell = DataGridView1.Item(1, e.RowIndex) 
    End If
  cellEnterInUse=false
  End If
End Sub

It's a little more involved than I really wanted, but I trust Linda Liu (I've received help on several occassions from her on on the MSDN site), so I'm sure the solution would have worked had I implemented it.

Thanks.

On a side note, it is frustrating to know that (according to the posts in that thread) the team in charge of the grid control knows of the issue, and must be aware of the fix(es) posted by their collegue, but have not implemented the fixes in the grid itself.
