Opening page from email link doesn't populate form with data

Hi,

 

Did you debug your code by placing a breakpoint at code behind of tests.aspx and check step by step what's happening?

 

based on your statements, my guess is that you are using some session variables in your code behind which are set correctly when you navigate from one form to another, but those are not set correctly when you click link from email.

 

you have to write code of https ://abc.xyz.com/sites/def/Pages/tests.aspx?uID=56 in such a way that it can be executed independently i.e. the URL has all the values needed to run the code.
