I solved my self.

C#

public void SelectAllDataGridViewCheckBoxColumn(CheckBox chk, DataGridView dgv, string DatagridViewColumnName)
       {
           if (chk.Checked == true)
           {
               if (dgv.Rows.Count > 0)
               {
                   foreach (DataGridViewRow row in dgv.Rows)
                   {
                       (row.Cells[DatagridViewColumnName] as DataGridViewCheckBoxCell).Value = true;
                   }
               }
           }
           else if (chk.Checked == false)
           {
               if (dgv.Rows.Count > 0)
               {
                   foreach (DataGridViewRow row in dgv.Rows)
                   {
                       (row.Cells[DatagridViewColumnName] as DataGridViewCheckBoxCell).Value = false;
                   }
               }
           }
       }
