I am trying to make a database program in visual studio 2008....i need to show some blank or empty rows in a datagrid to make my program look nice for this i used

public frmMainWindow()
        {
            InitializeComponent();
             dataGridView1.Rows.Add(7);
             dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
        }

i needed to select whole rows when a user select a cell in a data grid so i used the second line code for it...
but i don't wish user to be able to select the empty cell or rows....

i tried this code

<pre lang="cs">private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (dataGridView1.CurrentCell.Value == null)
    {

        dataGridView1.ClearSelection();
    }

but a flash of section occurs before the selection is removed using that code...
i want it not to be selected at all even for a second...
thank you for your help

I got the solution myself:

C#

private void dataGridView1_SelectionChanged(object sender, EventArgs e)
        {
          if (dataGridView1.CurrentCell.Value == null)
           {

           dataGridView1.ClearSelection();
            }
        }

using this the flash of selection did not appeared....
