Answer 1

I found my own solution... I found that I could not have a DateTimePicker control bound to the dataset. When the DateTimePicker control was bound to the dataaset, the data would not display in any of the controls on the form. When I "un-bound" the DateTimePicker control, then the data woudl display properly. I bound an edit box to the date column and then updated the DateTimePicker control when the value of the edit box changed.
