You must use DataGridView.CellValidating Event like this :

    private void dataGridView1_CellValidating(object sender, 
                                           DataGridViewCellValidatingEventArgs e)
    {
        if (e.ColumnIndex == 1) // 1 should be your column index
        {
            int i;

            if (!int.TryParse(Convert.ToString(e.FormattedValue), out i))
            {
                e.Cancel = true;
                label1.Text ="please enter numeric";
            }
            else
            {
                // the input is numeric 
            }
        }
    }
