Answer 1

读入数据到List<T>
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType==DataControlRowType.DataRow) 
{ 
  CheckBox  chk= e.Row.FindControl("CheckBox1") asCheckBox;
  if(chk!= null &&list.Contains("条码"))
  {
    chk.Checked=true;
  }
}
}

Answer 3

用js循环GridView,找到和textbox对应的数据勾选之!

Answer 4

若textbox条码扫描框的id是TextBox1,
GridView的第0列示CheckBox,第一列是要和TextBox1进行匹配的,
则在TextBox1输入条码后按回车,执行js的test(),如下:
   <script language="javascript" type="text/javascript">
        function test() 
        {
            var gv = document.getElementById("<%=GridView1.ClientID%>");
            var chklist = gv.getElementsByTagName("input");
            var rowStr = "";
            for (var i = 1; i < gv.rows.length; i++) {                var myRow = gv.rows(i);
                if(myRow.cells(1).innerText ==document.getElementById("TextBox1").value)//第一列和textBox1比较
                    chklist[i-1].checked = "checked";//设置勾选
            }
            return false;
        }
    </script>

前台 
function selectAll(obj) {
                    var allInput = document.getElementsByTagName("input");
                    //alert(allInput.length);
                    var loopTime = allInput.length;
                    for (i = 0; i < loopTime; i++) {
                        //alert(allInput[i].type);
                        if (allInput[i].type == "checkbox") {
                            allInput[i].checked = obj.checked;
                        }
                    }
                }
后台：
 foreach (GridViewRow gvr in this.GridView1.Rows)
            {
                CheckBox cb = (CheckBox)gvr.FindControl("chk_Del");
                if (cb.Checked)
                {
                    Label lblId = (Label)gvr.FindControl("LblCommentID");
                    int id = Convert.ToInt32(lblId.Text);
                    int re = BLL.CommentManager.DelComment(id);
                    if (re != -1)
                    {
                                         
                        DelQuestionMethod(id);
                        GVBind(this.GridView1, this.AspNetPager5, true);
                    }
                                    }
            }
