I am working on a web application after several years away from the web, so for all practical purposes, I am a newbie. I have set up my form with the default settings, as described in the JumpStart. Perhaps I don't understand how this was meant to work but I expected that, unless I specifically issued a save, there would not be a postback. I am getting a postback for each data field and, worse yet, the value entered in the control is not sticking, although values that I enter programmatically are sticking. I have checked, double-checked, triple-checked, etc. to make sure that I have the BindingSource and BindingSourceMember set correctly. The value isn't even showing up in the dataset when I check it in the TextChanged event.

I'm probably missing something obvious but can't see any difference between what I have and what's in the jumpstart. Any ideas for where to start looking? Thanks.
