Okay, so I have this page, which has one Ajax:AsyncFileUploader also some other ajax stuff like ModelPopUpExtender etc. The problem is the two buttons in the page, of Cancel and Submit, both of them firing up but none is posting back, while I made sure none of the fields in the page are blank.
I know the events are firing up, because I debugged the JavaScript in Firebug (a single step into and continue process took more than 4 min, while I was just almost held the F10 key for stepping into, down!)
If anyone wants code, please tell me I’d post it, but buttons are just in normal code so nothing special, that’s why I am not posting the code, but in case required I can post entire page’s code (which is pretty long I’d tell you, not really though, but at least just for posting purpose in here, somewhat around 200 lines).
Any help anyone?
Edit: As per comment I am posting the code
code: aspx page

I copied your code, experienced the problem, fixed it and now the postback is happening just fine. MEVDueDate is always saying “IsValid=false” and because of that the PostBack was not getting to Page_Load (that is the expected behavior of that validator).
You need to change:
with this:
Select today on the calendar for Due Date, click cancel button and you should have a full postback. Please see that you are saying that min and max allowed dates are both today, so today is the only valid date that will allow the post-back to fire.
The reason is that your calendar picker writes on the textbox “03/08/2012” but the ToShortDateString() retrieves a string with another date format. You end up comparing “03/08/2012” with “08/03/2012”.
You need to make sure the date format you use to set MEVDueDate.MinimumValue is according to the format that calendarPicker (CalDueDate) puts in txtDueDate.
