Relation between master page and non master page

Question

There is a page Login.aspx having a Label control as "Lbl_LoginExpired". There is also a MasterPage. I want to change the text of "Lbl_LoginExpired" from within the Master Page. How can i achieve this?

Note: 1) Login.aspx is NOT a Content page.

2) Label label1=new (Label)Login.FndControl("Lbl_LoginExpired") is NOT working in MasterPage.

Answer 1

If there is no master page- content relationship between these 2 pages. I think your options are limited. Also i am assuming Lbl_LoginExpired is not a part of an user control that you can register in both pages. I would recommend using Session object to pass this information between these 2 pages.

Hence in your master page

 Session["expiredtext"] = "Your login has been expired";

And in your login pag check this session value whether it is null or not and show the content of it.

Lbl_LoginExpired.Text=Session["expiredtext"]?.ToString();

Also do not forget to reset (or abonden session when user logs out)
