+TargetMilestone: ---
+Summary: IsPostback returns true during AJAX call with .Net and false with Mono
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+A third party web grid contorl we uses implemented Ajax scrolling that 
+works correctly in .Net but not in Mono.  After some investigation we 
+found out Mono and .Net behaves different with the Ajax parameter they 
+It turns out Mono is checking for __VIEWSTATE to determine is web request 
+is a postback or not while .Net checks for either __VIEWSTATE or 
+Steps to reproduce the problem:
+1. Create an Ajax call with HttpRequestMethod = "POST", and sent() with 
+parameter "__EVENTTARGET=webcontrolId&__EVENTARGUMENT=XmlHttpRequest&..."
+2. Create a website to accept the Ajax call
+3. Print out IsPostback value
+Actual Results:
+Ajax call is not considered as postback
+Expected Results:
+Ajax call should be considered as postback
+How often does this happen? 
+Additional Information:
+I am not sure if the .Net behavior is correct in respect to documentation 
+or if the web control is coded to a bug, but we would like the behavior of 
+Mono to match .Net
