Get and cast Masterpage UserControl from Content Page to access specific UC Property

Question

I have a MasterPage (MyBoxx.Master) referencing 2 usercontrols :

<%@ Master Language=\"C#\" AutoEventWireup=\"true\" CodeFile=\"MyBoxx.master.cs\" Inherits=\"         


        

Answer 1

Well, I found several working solutions... and I think I understood how/why it worked earlier

1) it seems that compilation has a role to play in this. If I comment the line, compile the site, and then try to add the line again, the type uxHeader is "available" in VS and I can compile the site back again with the line uncommented...

2) As first solution is obviously not a long-term solution, I found that referencing the user-control (without actually using it of course) in the content page aspx would do the trick :

<%@ Register TagPrefix="uc1" TagName="Header" Src="Header.ascx" %>

3) I also tried this one, which I find the cleanest... In the master page, expose a public property :

public uxHeader PageHeader
{
    get
    {
        return Header1;//Header1 is the id of the userControl dropped in masterpage
    }
}

In the content page aspx, I then put :

<%@ MasterType VirtualPath="~/DBoxx.master"%>

then, still in the content page, but in the codebehind, and after a compilation of the site, I can use :

this.Master.PageHeader.ShowSearch = false;

Hope this will help the ones searching for help on the subject in the future. I see this is a recurent question
