如何访问在内部MasterPage中找到的控件 [英] How to access Controls found in inner MasterPage

问题描述

大家好，

我有MasterPage1和MasterPage2，它的母版页是MasterPage1

和名为MyPage的ASP.net页面，其母版页面为MasterPage2，例如:

MasterPage1>>>> MasterPage2>>>>>>>>> MyPage

我想从MyPage访问在MasterPage2中找​​到的控件
我可以访问外部MasterPage中的控件，但是我无法访问内部MasterPage中的控件，尽管我认为这很容易

我尝试过但未与我合作:

Hi guys,

I have MasterPage1 and MasterPage2 that its master page is MasterPage1

and ASP.net page called MyPage its master page is MasterPage2 like that:

MasterPage1 >>>>> MasterPage2 >>>>>>>>>> MyPage

I want to access controls found in MasterPage2 from MyPage
I can access the controls in the outer MasterPage, but the problem i cannot access the controls in the inner MasterPage, Although I thought it easy

I try that but not worked with me:

LinkButton tb = this.Master.FindControl("lbtnContact") as LinkButton;

推荐答案

我认为您应该使用以下代码:

I think you should use following code:

ContentPlaceHolder cp = this.Master.Master.FindControl("MainContent") as   ContentPlaceHolder;
LinkButton lb = cp.FindControl("lbtnContact") as LinkButton;

您的主要(最顶层)母版页具有contentplaceholder，例如:

where your main(topmost) masterpage has a contentplaceholder like:

<asp:contentplaceholder id="MainContent" runat="server" />

希望对您有所帮助.

I hope it will help you.

尝试以下代码:

Try this code:

LinkButton tb = (LinkButton)Master.FindControl("lbtnContact")

祝你好运

Good Luck
