从内容页面访问母版页控件 [英] Access Master Page control from the Content page

问题描述

嗨
我有一个母版页，从中可以得出所有页面.在主页上，我有一个名为userLoginName的标签(默认情况下为空白.)

在登录页面上，在登录按钮的单击事件上，我有以下代码:

Hi
I have a master page from which i derive all the pages. On the master page i have a label called userLoginName (by default the text is blank.)

From the login page , on the click event of the login button i have this code:

Dim _logName = Trim(LoginName.Text)
Dim _pwd = Trim(Password.Text)

If Me.ValidateUser(_logName, _pwd) = True Then

    'display users etails

    Dim mpLabel As Label
    mpLabel = CType(Master.FindControl("userLoginName "), Label)

    'change the userLoginName text to: your login is successfull + user Name
     mpLabel.Text = "your login is successfull" & _logName

    'Redirect user to the appropriate page
    If ViewState("_UserPrivilege") = "Administrator" Then
        Response.Redirect("~/Adminstrator/index.aspx")
    ElseIf ViewState("_UserPrivilege") = "Terminal User" Then
        Response.Redirect("~/TerminalUsers/index.aspx")
    End If

Else
    StatusLabel.Text = "Please your login Name or Password is incorrect."
    Exit Sub
End If

将页面重定向到适当的页面后，然后我看不到消息+用户登录名.

请帮助

After Redirecting the page to the appropriate page, then i dont see the message + user login name.

plz any help

推荐答案

此代码存在各种问题.但是，总的来说，我一直这样做的方法是为我所有的页面创建一个基础页面类.在该基类中，我公开了一个属性，该属性是页面的Master属性，转换为我正在使用的MasterPage类的类型.完成此操作后，我可以轻松地与内容页面中的母版页进行交互.但是，我永远不会直接公开文本框，而是公开一个属性来获取和设置其文本.

There''s all sorts of issues with this code. However, at the core, the way I always do this, is to create a base page class for all my pages. In that base class, I expose a property which is the Master property of the page, cast to the type of the MasterPage class I am using. Having done that, I can easily interact with my master page in my content pages. However, I would NEVER expose the textbox directly, I''d expose a property to get and set it''s text.
