linkbutton相关问题 [英] linkbutton related question

问题描述

我在主页面中使用名称为linkin的linkbutton进入登录表单。在我使用linkbutton登录表单后，我想在主页面中将linkbutton的名称更改为注销。

 部分 类网站
 继承 System.Web.UI.MasterPage 
 
 
 
 受保护的  Sub  Page_Load（ ByVal  sender  As  对象， ByVal  e  As  System.EventArgs）句柄 我 .Load 
 我 .Label1.Text =会话（  name ）
  Me  .Label1.Visible =  True  
 我 .Label3.Visible = 真 
 结束  Sub  
 
 受保护  Sub  LinkBut​​ton1_Click（ ByVal  sender  As  对象， ByVal  e  As  System.EventArgs ）句柄 LinkBut​​ton1.Click 
 
 
 
 我 .LinkBut​​ton1.Text =  退出 
 我 .Response.Redirect（  Login.aspx）
 
 
 
 
 结束  Sub  
 < span class =code-keyword>结束 类 

i使用它不起作用。我可以这样做吗

解决方案

由于LinkBut​​ton1是触发此事件的控件，为什么不处理当前发送者在这里？

  Dim 按钮作为 LinkBut​​ton =  TryCast （发件人，LinkBut​​ton）
 button.Text =  退出 

你确定你是吗？登录后需要将用户重定向到login.aspx页面？对我来说，这似乎是一个逻辑错误。 的

i use linkbutton with name as signin in master page for go to login form. after i go to login form by using linkbutton then i want to change the name of linkbutton as signout in master page.

Partial Class Site
    Inherits System.Web.UI.MasterPage



    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Me.Label1.Text = Session("name")
        Me.Label1.Visible = True
        Me.Label3.Visible = True
    End Sub

    Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click



        Me.LinkButton1.Text = "Sign out"
        Me.Response.Redirect("Login.aspx")




    End Sub
End Class

i used this it not work.how can i do it

解决方案

Since LinkButton1 is the control that triggers this event, why don't you handle the current sender here?

Dim button As LinkButton = TryCast(sender, LinkButton)
button.Text = "Sign out"

Are you sure you're required to redirect the user to login.aspx page once he has logged in? For me, this seems to be a logical error here.
