just an FYI, if you are going to use "DataGridView1.SelectedRows(0).Selected = false", make sure that there are rows in the grid...

ex...

If DataGridView1.Rows.Count > 0 Then
DataGridView1.SelectedRows(0).Selected = false

Yes. I put it on the function LoadToGrid and also on the lost_focus i put also the clearselection() . but on first load the grid focused and highlighted the first row and then when i click the button new or any button on my form the highlighted on the grid was gone. i think this is good enough to have my requirement done. Thanks.

Just as a matter of interest, Leslie, did the ClearSelection() method work from the LoadToGrid() method or only when you put it in the GotFocus eventhandler?

Hello Thanks for the reply i really appreciate it. and also if this is for the other who encountered same problem as mine they can do also just like this. Me.grd1.ClearSelection().

Assuming you're calling the LoadToGrid() method from Form_Load, the error message suggests that no rows are selected at that stage. So the first row must get selected just after the form loads.

If that's the case, then I think I'd try handling the Form's GotFocus event (or possibly the Activated event) instead and put that line in the eventhandler:

Private Sub Form1_GotFocus(sender as Object, e as EventArgs) _
Handles Form1.GotFocus

grd1.SelectedRows(0).Selected = False

End Sub

From memory, I don't think this event shows up in the VS Properties box so you'll just have to paste it in.

Thanks you, but i have this error "Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index" this is my code.

        Private Sub LoadToGrid()

            Dim ConnString As String = CurrentFacade.OnlineConnectionString
            Dim SQLString As String = "SELECT   ID, LabelDesc, LengthDescription, FontSize, XCoor, YCoor, FontName, FontColor, case     TextJustication when 1 then 'Left' when 2 then 'Center' when 3 then 'Right' end as TextJustification, BlacklistDictionary FROM   CustomField_C"

            Dim SqlDataAdapter1 As New SqlDataAdapter(SQLString, ConnString)
            Dim DataSet1 As New DataSet()

            SqlDataAdapter1.Fill(DataSet1, "CustomField_c")
            grd1.DataSource = DataSet1.Tables("CustomField_c")

    // this is to hide the first colurm. which is the ID
            grd1.Columns(0).Visible = False
            grd1.SelectedRows(0).Selected = False

        End Sub

If DataGridView1 is your DGV, then try putting this line in your Form1_Load:

DataGridView1.SelectedRows(0).Selected = False
