I have a setting in my web.config
<sessionstate mode="InProc" cookieless="AutoDetect" timeout="90">.In normal scenarios this is working fine.
I have a web page where when I am clicking a button the form data will be inserted to db.
If I remove cookieless="AutoDetect" from the node mentioned earlier while clicking the button it is throwing the error "Invalid postback or callback argument".
This is making me weird. Please give me some clue.
