母版页
public partial class 母版页_Default : System.Web.UI.Page
{
protected void Page_PreInit(object sender, EventArgs e) //在内容页和母版页合并之前运行的事件
{
if (Session["aa"] != null) //虚判断
{
Page.MasterPageFile = "~/母版页/mp2.master"; //获取或设置母版页的文件名
}
}
protected void Page_Load(object sender, EventArgs e)
{
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
((Label)Master.FindControl("Label1")).Text = DropDownList1.SelectedValue; //获得母版页中Lable1控件对他赋值
Label1.Text = DropDownList1.SelectedValue;
}
}
重点:Page.MasterPageFile {
protected void Page_PreInit(object sender, EventArgs e) //在内容页和母版页合并之前运行的事件
{
if (Session["aa"] != null) //虚判断
{
Page.MasterPageFile = "~/母版页/mp2.master"; //获取或设置母版页的文件名
}
}
protected void Page_Load(object sender, EventArgs e)
{
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
((Label)Master.FindControl("Label1")).Text = DropDownList1.SelectedValue; //获得母版页中Lable1控件对他赋值
Label1.Text = DropDownList1.SelectedValue;
}
}
Master.FindControl
2、检测不同的浏览器,应用不同的母版页
1、属性定义
<%@ Page Language="C#" MasterPageFile="~/MasterPage/MasterPage1CS.master"
ie:MasterPageFile="~/MasterPage/MasterPageForIE.master"
Safari:MasterPageFile="~/MasterPage/MasterPageForSafari.master"
Mozilla:MasterPageFile="~/MasterPage/MasterPageForMozilla.master"
Netscape:MasterPageFile="~/MasterPage/MasterPageForNetscape.master"
Opera:MasterPageFile="~/MasterPage/MasterPageForOpera.master"
%>
ie:MasterPageFile="~/MasterPage/MasterPageForIE.master"
Safari:MasterPageFile="~/MasterPage/MasterPageForSafari.master"
Mozilla:MasterPageFile="~/MasterPage/MasterPageForMozilla.master"
Netscape:MasterPageFile="~/MasterPage/MasterPageForNetscape.master"
Opera:MasterPageFile="~/MasterPage/MasterPageForOpera.master"
%>
2、用代码动态检测
protected void Page_PreInit(object sender, EventArgs e)
{
if (Request.Browser.IsBrowser("IE"))
{
this.MasterPageFile = "MasterPageForIE.master";
}
else if (Request.Browser.IsBrowser("Mozilla"))
{
this.MasterPageFile = "MasterPageForMpzilla.master";
}
else if (Request.Browser.IsBrowser("Netscape"))
{
this.MasterPageFile = "MasterPageForNetscape";
}
else
{
this.MasterPageFile = "MasterPage1CS.master";
}
}
{
if (Request.Browser.IsBrowser("IE"))
{
this.MasterPageFile = "MasterPageForIE.master";
}
else if (Request.Browser.IsBrowser("Mozilla"))
{
this.MasterPageFile = "MasterPageForMpzilla.master";
}
else if (Request.Browser.IsBrowser("Netscape"))
{
this.MasterPageFile = "MasterPageForNetscape";
}
else
{
this.MasterPageFile = "MasterPage1CS.master";
}
}
