小弟我想获取GRIDVIEW控件中插入CHECKBOX控件中的一个值

我想获取GRIDVIEW控件中插入CHECKBOX控件中的一个值
int intCount = this.GridView1.Rows.Count;
  for (int i = 0; i < intCount; i++)
  {
  CheckBox CheckBox1 = this.GridView1.Rows[i].Cells[5].FindControl("CheckBox1") as CheckBox;
  if (CheckBox1.Checked)
  {
  string title =this.GridView1.Rows[i].Cells[1].Text;
  SqlWebDal swd = new SqlWebDal();
  string sqlcontent = "UPDATE Tips SET Release ='true' WHERE Title='" + title + "'";
  swd.GetSqlCmd(sqlcontent);
  }
  }
  Response.Write("<script language='javascript'>alert('发布成功')</script>");
  Response.Write();

------解决方案--------------------------------------------------------
Checkbox test =(CheckBox)GridView1.rows[i].FindControls("yourControlName")；

string title = test.Checked.toString()
