Send File then Response.Redirect the Another page but Session objects null

[YAVUZ]

Hi,

I use RadProgressManager (2009.2.701.35) and RadUpload in my web page. I fill the blanks and send the file in page. Then I push the send to Approve button. This button save the some fields and filenames then Response.Redirect to root page. When response on the root page session objects values null. How to avoid this error ?

Hi,

Thank you for your reply. I will paste the code behind source.

Hello YAVUZ,

I'm afraid I couldn't follow your logic easy. Which Session object is null? I noticed you have several Session objects:

- Session["pNewGuid"]
- Session["targetFolder"]
- Session["redirected"]

Since the scenario is more complex - could you please isolate it in a simple runnable project and send it us?
We will examine the files locally and try to find a solution.
