如何在MasterPage中检查GridView中CheckBox字段的属性？
Design（Master.master）：
How to Check property of CheckBox Field in GridView within a Master Page??
Design(Master.master):
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<pre lang="xml"><head runat="server">
<title>Untitled Page</title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
<style type="text/css">
.style1
{
width: 100%;
}
</style>
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
<asp:Panel ID="Panel1" runat="server">
<asp:GridView ID="GridView1" runat="server"
AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="Operation">
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Day">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%#Eval("DayName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<br />
<asp:Button ID="Button9" runat="server" onclick="Button9_Click" Text="Button" />
</asp:Panel>
Default2.aspx（来源视图）：
Default2.aspx (Source View):
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
MasterPage.master.cs（代码视图）：
MasterPage.master.cs (Code View) :
protected void Page_Load(object sender, EventArgs e)
{
con.Open();
SqlDataAdapter da = new SqlDataAdapter("Select *from Day", con);
DataTable dt = new DataTable();
da.Fill(dt);
con.Close();
GridView1.DataSource = dt;
GridView1.DataBind();
}
protected void Button9_Click(object sender, EventArgs e)
{
foreach (GridViewRow gvrow in GridView1.Rows)
{
CheckBox chk = (CheckBox)gvrow.FindControl("CheckBox1");
if (chk != null && chk.Checked)
{
}
}
}
运行 Default2.aspx 页面并选中 CheckBox1 然后单击按钮。
但是，在 MasterPage ，所有时间显示 Checked = false 。
那么，如何检查CheckBox的属性是真/假正确基于用户在MasterView中的GridView中??

推荐答案
你应该在里面绑定GridView！IsPostBack就像...
You should Bind GridView inside!IsPostBacklike...
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
con.Open();
SqlDataAdapter da = new SqlDataAdapter("Select *from Day", con);
DataTable dt = new DataTable();
da.Fill(dt);
con.Close();
GridView1.DataSource = dt;
GridView1.DataBind();
}
}
纠正此问题。然后试着让我知道。
