常常會碰到需要對GridView裡的checkbox作全選的動作，用jQuery來做的話，其實還滿方便的
在此記錄一下
[default.aspx]
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="default.aspx.cs" Inherits="Lab_CheckAllInGridView._default" %>
<!DOCTYPE html>
<html>
<head runat="server">
<title>CheckBox 全選</title>
<script type="text/javascript" src="Scripts/jquery-2.0.2.min.js"></script>
<script type="text/javascript">
// 選擇 GridView 全部的 checkbox
// 傳入控制checkbox全選的checkbox物件
function checkAll(header) {
$('#<%= gvData.ClientID %> input[type=checkbox]').prop("checked", header.checked);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="gvData" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="選取">
<HeaderTemplate>
<asp:CheckBox ID="cbHeader" runat="server" onclick="checkAll(this);" />
選取
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="cbDel" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Name" HeaderText="姓名" />

</Columns>
</asp:GridView>

</form>
</body>
</html>

}
