Hi Tim,
I figured out a few things but still can't get everything to work right. I have code in the Text_Changed event, which is triggering a post back (because the user has to press ENTER to get it to fire) with no place to update my session dataset variables. Consequently, I get an extra trip to the back end before saving my data set variables and lose everything that was just entered. I disabled the submit for all but one of my buttons except for a save button, hoping to route all the submits through there so I could update the session variables in the click event of the button but that apparently fires after the submit as well. Then I tried saving the session variables in the unload of that button, hoping the dataset variables would save right before posting but still no luck. Next I plan to abandon the Text_Changed event and put all the code I want either in the page load or in that button click.
Basically, my problem is that the users want the responsiveness of the desktop environment but management wants everything on the web so they can get to the data (users are widely distributed) and, probably, keep the cost of the user computers down. I lost the fight trying to convince them to stick with Windows Forms for this application, at least for now.
I haven't really looked at Silverlight. What would that gain me in this process?
Thanks, as always, for your help.
Linda

>>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.

Are you instantiating your business objects in the Page Load event so they get done every time? Are you re-retrieving data every time the page posts back? What I often do depending on what is the data; I will save a copy of the DataSet in a session variable. Check out the jump start for Web Forms Step 12 for the Order Edit Form. The data is retrieved and saved in a session for the order and detail but the Shippers and Employees are retrieved every time a post back occurs. This should give you some ideas on what you may want to do.
