My work mate is having this problem as well, we haven't had a chance to do much in the way of investigation.
Steps that reproduce the problem in a textbox in a datagrid with a validation rule attached.
- Enter some illegal content in such a way that one backspace should return you to legal content.
- Hit back space - the text box is still showing an error when it shouldn't be
- Hit backspace again and the error clears
Has anyone come across this and know of a work around?
Thanks in advance!
