I have read what seems like a million "Invalid postback or callback argument." threads, but I have yet to find any help on my issue.
First: As astonishing as it seems I have enableEventValidation="false" validateRequest="false" in the "pages" section of the web.config AND
EnableEventValidation="false" in the page itself, just to try and troubleshoot the issue... I still get the error.
Second: I am only getting the error when I run my site in the web browser control for a windows forms application - it works fine when run from a browser.
What I see in fiddler is that the last control that posts back to the page has a sweet little ASCII "square" character at the end of the value when viewing the "WebForms" tab - only when run from the broswer
control. I also do not see that sweet little character when I am in the TextView tab of fiddler. Change the last control that posts back, the sweet little square moves to that control.
I have compared the "View source" from within the browser control and IE, and as expected they are identical (except whitespace resulting from the source of the control opening in a text editor and the browser oeping in a browser I would guess).
I am completely at a loss at this point and have read nothing that gets me close... I am not using any javascipt to insert vlaues, change controls, force post backs, etc. etc. etc. The meat of it is just a form with some dropdowns with auto-postback set
