Dataview Dates

[zatch]

I am displaying values from a database on my form with textboxes which pull data from a dataview. I then update the data in the textboxes to update the dataview and eventually the dataset. This works fine for everything except when I try to update date fields to null. When I try to update a date field to null, it appears to update until I leave the textbox or try to save the changes to the dataset. When I do either of these two things, the original data reappears in the textboxes. Has anyone run into this?

Thanks in advance.
