使用服务端和客户端两种方法 模拟网易邮箱实现全选，全不选的功能
服务端和客户端的差别是 服务端在每次全选或全不选是都要刷新界面 而客户端不会
服务端：
前台
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" //使用的是guidview控件
DataKeyNames="id" DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="xwname" HeaderText="xwname"
SortExpression="xwname" />
<asp:BoundField DataField="fwl" HeaderText="fwl" SortExpression="fwl" />
<asp:BoundField DataField="id" HeaderText="id" InsertVisible="False"
ReadOnly="True" SortExpression="id" />
<asp:BoundField DataField="url" HeaderText="url" SortExpression="url" />
<asp:CheckBoxField DataField="isnull" HeaderText="isnull"
SortExpression="isnull" />
<asp:TemplateField>
<HeaderTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="True"
oncheckedchanged="CheckBox1_CheckedChanged" />
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<br />
<br />
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:xinlangConnectionString %>"
SelectCommand="SELECT * FROM [zT_huati]"></asp:SqlDataSource>
</div>
后台：
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
CheckBox ck1 = sender as CheckBox;
foreach (GridViewRow gvr in GridView1.Rows) {
(gvr.Cells[5].FindControl("checkbox2") as CheckBox).Checked = ck1.Checked;
}
}
客户端：
客户端的没用后台 主要是用javascript; 来实现
<head runat="server">
<title></title>
<script type="text/javascript"> //js
function aaa(sender) {
var grd = document.getElementById("GridView1");
for (var i = 1; i < grd.rows.length; i++) {
grd.rows[i].cells[5].getElementsByTagName("input")[0].checked = sender.checked;
}
}
</script>
</head>
