Web Forms :: How To Set Value Of Master Page Control From Content Page
May 14, 2010
I am developing a website. I have created a master page called Master.master which has a asp Label contol in it. I have used this master page as a template for the after login pages.
I am setting the value of the label on the master page to the session variable of User_Id that is generated after successful login.
My problem is that I have to set the value of the asp Label in the master page manually in the code behind of every after login page I visit.
Is there any way to retrieve the value of the session User_Id directly in/from the master page's code behind rather than setting the value in each and every page's code behind file.
Basically i want to set value of a master page label directly to a session that is generated after successful login. How do I do it?
