跨页面实现多选

<form id="form1" runat="server">
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="ObjectDataSource1" AllowPaging="True" OnRowDataBound="GridView1_RowDataBound">
            <Columns>
                <asp:BoundField DataField="STATIONID" HeaderText="STATIONID" SortExpression="STATIONID" />
                <asp:TemplateField>
                    <ItemTemplate>
                     
                        <asp:CheckBox ID="chkSelect" runat="server" onclick="checkbox_onchange()"/>
                    </ItemTemplate>
                
                </asp:TemplateField>
                <asp:BoundField DataField="STATIONNAME" HeaderText="STATIONNAME" SortExpression="STATIONNAME" />
                <asp:BoundField DataField="SECONDNAME" HeaderText="SECONDNAME" SortExpression="SECONDNAME" />
                <asp:BoundField DataField="THIRDNAME" HeaderText="THIRDNAME" SortExpression="THIRDNAME" />
                <asp:BoundField DataField="ALLROAD" HeaderText="ALLROAD" SortExpression="ALLROAD" />
            </Columns>
        </asp:GridView>
        <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetAllList"
            TypeName="BusManage.BLL.BusStation"></asp:ObjectDataSource>
            <input id="eleName" readonly
type="text" size="53" runat="server"> <input id="eleValue" type="hidden" runat="server">
    </form>

 .cs绑定

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    ...{
        if(HdnSelectedValues.Value.IndexOf(((Literal)e.Item.Cells[1].FindControl("TitleShow")).Text) >= 0 )
        ...{
            HtmlInputCheckBox ChkSelected = (HtmlInputCheckBox)(e.Item.Cells[0].FindControl("ChkSelect"));
            ChkSelected.Checked = true;
        }
    }

下面javarscript放页面下方

<script language="javascript" type="text/javascript">
       
        SetCheckBoxStatus();
        function SetCheckBoxStatus()
        ...{
            var tb = document.getElementById("GridView1");
            var eleValue = document.getElementById("eleValue").value;
             
            for(var i=1;i<tb.rows.length-1;i++)
            ...{
                var chk =   tb.rows[i].cells[1].firstChild;
                 
                if(eleValue.indexOf(tb.rows[i].cells[2].innerText+",") >-1)
                ...{
                    chk.checked = true;
                }
                
            }
        }

        function checkbox_onchange()
        
         ...{
              var tb = document.getElementById("GridView1");
            var eleValue = document.getElementById("eleValue");
             
            for(var i=1;i<tb.rows.length-1;i++)
            ...{
                var chk =   tb.rows[i].cells[1].firstChild;
                var id  =   tb.rows[i].cells[2].innerText; 
                eleValue.value = eleValue.value.replace(id+ ",","");
                if(chk.checked)
                ...{
                     eleValue.value = eleValue.value + id+ ",";
                } 
                
            }
           
       
        }
