MasterPage.Master > Which page will be next loaded as a child?

I would like to know, in the Page Load event of my MasterPage.Master which page sent the request. will be loaded as child in the content.

Supposing, the user 开发者_运维问答clicks in my webpage <a href="Login.aspx">Login</a> can i get that value from the Page Load event of my MasterPage.Master for later processing?

Dim ThePageThatWillLoadAsChildIs as string =

You see i would like to use that, so when the request page is e.x. Login.aspx, inject in the form element of my webpage some attributes.

Have a look at Request.Url Property and get the necessary information there

I think what you are looking for is Request.UrlReferrer

Well this one does the trick (On the master page load)

Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
   Dim TheNextPageThatWillLoad As String = DirectCast(sender, MasterPage).Request.RawUrl
End Sub
