Question

Hi all, I'm using a Datagridviewcomboboxcolumn in to dsiplay some data in my datagridview. After binding the data to the datagridviewcombobox how can i make it display the first item in the box by default? My code is as follow DataGridViewComboBoxColumn col = new DataGridViewComboBoxColumn();             DataTable dt = getData();//get data from database             col.DataSource = dt;             col.DisplayMember = "LastName";             if (col.Items.Count > 0)//There is at least one item in the Combobox             {                 //Select the first item             }             dataGridView1.Columns.Add(col);
