问题描述
I have a Datalist Control, where there are multiple rows(3 rows per page).Each row has a checkbox as well. My requirement is that I want the checked items to come down in the Repeater control when I press the "Checkout" Button. But when I go to the next page the checked items on the previous page gets reset.
我尝试过的方法：
What I have tried:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" MaintainScrollPositionOnPostback="true" %>
<!DOCTYPE html>
<title>DL-A1
<div>
<asp:DataList ID="DataList1" runat="server" DataKeyField="bookid">
<itemtemplate>
<table><tbody><tr><td>
</td><td>
Title: <%# Eval("booktit") %><br>
Author: <%# Eval("bookaut") %><br>
Publisher: <%# Eval("bookpub") %><br>
Prc: <%# Eval("bookprc") %><br>
<asp:CheckBox ID="CheckBox1" runat="server" Text="Buy" Font-Bold="True" /><br>
</td></tr></tbody></table>
<asp:Repeater ID="rptPaging" runat="server" OnItemCommand="rptPaging_ItemCommand">
<itemtemplate>
<asp:LinkButton ID="lnkPage" runat="server" CommandName="Page" CommandArgument="<%# Container.DataItem %>"><%# Container.DataItem %>
<br>
<asp:Label ID="lbl1" runat="server" Text="Label" Font-Bold="True">
<br>
<br>
<asp:Button ID="Button1" runat="server" Text="Checkout" OnClick="extractCheckedVal" Font-Bold="True" Font-Size="X-Large" /><br><br><br>
<asp:Repeater ID="Repeater1" runat="server">
<headertemplate>
Total number of checked items: <%= v_tot %> <br>
Selected Items Are:
<itemtemplate>
<table><tbody><tr><td>
</td><td>
Title: <%# Eval("booktit") %><br>
Author: <%# Eval("bookaut") %><br>
Publisher: <%# Eval("bookpub") %><br>
