Visual Studio 2019, ASP.NET and C#
: I have a page, which can be called from couple of web pages. I need to return to the (Response.Redirect) page from where it was called by clicking a Back button. Possible soultion:
So I am retriving the called page URL by using CalledPageURL = Page.Request.UrlReferrer.ToString(). The value I retrivie is http://localhost:62000/Home.aspx
. Now I need to save this value, so that it would not get refreshed (null) during page Post Back
I am trying to use Session variable or ViewState options. But both of them are not working. They save the value successfully. But I try to retrive the vallue, I am getting null exception. Please let me know how to fix it.
Thank you in advance.
