Using master page and web forms in C#

Question

When using a master page, is there anyway i can see what web form is currently loaded or being loaded in the master page, so before this line:

<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">

</asp:ContentPlaceHolder>

i would like to see/get the web form that's going to be loaded in the master page, is this possible?

Answer 1

Yes, you have access to the Page property from the master page.

To see this in action, from the default Visual Studio template of an ASP.NET web application (which comes with a master page), dump this in the master where the h1 title is:

My ASP.NET Application <%= Page.GetType().Name %>

It will show up in the browser as My ASP.NET Application default_aspx or whatever page you're on.

Answer 2

I don't know if you have access to the page being loaded, but you can create a public property on the master page called eg currentPage and set it on the Page_Load of the page itself to the value you want. This way you can check it on the Site.Master code:

// on the Site.Master.cs
public string CurrentPage;


// on the page, inside the Page_Load event
((Site)this.Master).CurrentPage = 'My page';


// on the Site.Master
<%
if (CurrentPage == "My page")
{
    %>My page is loaded.<%
}
else
{
    %>Another page is loaded.<%
}
