C# winform中的datagridview控件标头加入checkbox，实现全选功能。

 /// <summary>
     /// 给DataGridView添加全选
     /// </summary>
     public class AddCheckBoxToDataGridView
     {
         public static System.Windows.Forms.DataGridView dgv;
         public static void AddFullSelect()
         {
             if (dgv.Rows.Count < )
             {
                 return;
             }
            this.dataGridView1.RowTemplate.Height = 23;
          System.Windows.Forms.CheckBox ckBox = new System.Windows.Forms.CheckBox();
            ckBox.Text = "全选";
            ckBox.Checked = true;
            System.Drawing.Rectangle rect =
            dataGridView1.GetCellDisplayRectangle(0, -1, true);
            ckBox.Size = new System.Drawing.Size(dataGridView1.Columns[0].Width, 18);
            ckBox.Location =new Point( rect.Location.X+2,rect.Location.Y+2);
            ckBox.CheckedChanged += new EventHandler(ckBox_CheckedChanged);
            dataGridView1.Controls.Add(ckBox);
         }
         static void ckBox_CheckedChanged(object sender, EventArgs e)
         {
             for (int i = ; i < dgv.Rows.Count; i++)
             {
                 dgv.Rows[i].Cells[].Value = ((System.Windows.Forms.CheckBox)sender).Checked;
             }
             dgv.EndEdit();
         }
     }

上面的类第一个方法，是为datagridview表头添加checkbox，第二个方法是全选功能实现。
