while hitting
ESC key twice when on a page containing an
update panel with a any control inside, say textbox or listbox im getting a
System.ArgumentException: Invalid postback or callback argument. I have checked in remaining browsers its working fine but in
Internet Explorer 8 its creating above said problem.
The possible solution i found, is making
EnableEventValidation="false either at page level or webconfig or disabling escape key . i dont want to go with 2 former solutions as either my site security will compromise and i dont want my escape key to disable as im using modal popup in page to hide.
Moreover im interested in why such weird behavior is happening.
Any Suggestions/Ideas appreciated.
