安装ASP.NET AJAX
安装Toolkit：
下载解压AjaxControlToolkit.zip移至
C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\AjaxControlToolkit
安装模板C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\AjaxControlToolkit\AjaxControlExtender\AjaxControlExtender.vsi
若安装失败，手工建立以下文件夹：
\My Documents\Visual Studio 2005\Templates\ItemTemplates\Visual C#
\My Documents\Visual Studio 2005\Templates\ItemTemplates\Visual Basic
\My Documents\Visual Studio 2005\Templates\ProjectTemplates\Visual C#
\My Documents\Visual Studio 2005\Templates\ProjectTemplates\Visual Basic
把SampleWebSite\Bin下的AjaxControlToolkit.dll和AjaxControlToolkit.pdb
复制至Binaries下。
打开VS，添加选项卡AjaxControlToolkit，添加项浏览至Binaries\AjaxControlToolkit.dll

在母板页"CS"加入:
public HyperLink MasterPageHyperLink3
{
get
{
return HyperLink3;
}
set
{
HyperLink3 = value;
}
}
{
get
{
return HyperLink3;
}
set
{
HyperLink3 = value;
}
}
在子页"源"加入:
<%@ MasterType VirtualPath="~/xoyozo/xoyozo.master" %>
即可在子页重写它:
Master.MasterPageHyperLink3.NavigateUrl = "ddddddd.html";
但最好放在Page_LoadComplete:
protected void Page_LoadComplete(object sender, EventArgs e)
{
}
{
}
