更改母版页中按钮的文本 [英] change the text of button in master page

问题描述

我正在尝试从aspx页面更改母版页中按钮的文本。



我将以下内容放在母版页中：

Hi,

I am trying to change the text of a button in master page from an aspx page.

I put the following in the master page:

public LinkButton LButton
    {
        get { return LButton; }
        set { LButton = value; }
    }

然后我在.aspx页面中添加了以下内容：

then i added the following in the .aspx page:

<%@ MasterType VirtualPath="Site.Master" %>

最后在我的背后的代码中：

lastly in the code behind i put:

Master.LButton.Text = "logout";

< br $>




i得到错误消息：



用户代码的stackoverflow异常！它指向：

i get an error that says:

stackoverflow exception by user code! and it is pointing at:

public LinkButton LButton
    {
        get { return LButton; }
        set { LButton = value; }
    }

作为循环！



please帮助......

as a loop!

please help...

推荐答案

你的获取正在返回LButton，所以将进入相同的get等等。如果你有一个LinkBut​​ton，你试图返回，那么你的财产必须被称为LButton以外的东西。

Your "get" is returning LButton, so will go into the same get and so on. If you have a LinkButton you're trying to return then your property has to be called something other than LButton.

<asp:LinkButton ID="MyLinkButton" runat="server" />

public LButton {get {return MyLinkButton;} }

或者，如果您只想在母版页上创建一个名为LButton的属性，您将在其他地方使用

Or if you just want to create a property called LButton on the master page you will use elsewhere just use

public LinkButton {get;set;}

但它是最好的做法是不公开这样的控件，而是设置要更改的值的属性，因此要有一个名为ButtonLabel的字符串属性，并且在设置属性时主页面会更新LinkBut​​ton。

However it is best practise to not expose controls like this but to set up properties for the values you want to change, so have a string property called "ButtonLabel" or something, and the master page updates the LinkButton when the property is set.

我只在.aspx代码中添加以下内容：

I found a solution...

I only put the following in the .aspx code:

Button l1 = Page.Master.FindControl("Button1") as Button;
        l1.Text = "logout"; 

并且有效：）

and it works :)
