DataGridView单元格自动完成

注意：该方法最大的不足之处就是会导致表格很卡，忘高手知道怎么规避卡的现象就指点一二(已修正)

private void GridDetail_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
            if (GridDetail.CurrentCell.ColumnIndex != 1)
                return;
            TextBox tb = e.Control as TextBox;
            tb.AutoCompleteSource = AutoCompleteSource.CustomSource;
            tb.AutoCompleteMode = AutoCompleteMode.Suggest;
            //定义一个数组
            string[] array = new string[] { "11", "12", "13", "22", "23", "24" };
            //整体赋值给AutoCompleteCustomSource 
            tb.AutoCompleteCustomSource.AddRange(array);
            //List<string> list = new List<string>();
            //list.AddRange(new string[] { "11", "12", "13", "22", "23", "24" });
            //循环赋值会导致卡的现象
            //foreach (string s in list)                
                //tb.AutoCompleteCustomSource.Add(s); 
        }
