John,

I'm not sure I understand your control model. Our DateTimeControl consists of a UserControl, on which two TextBoxes (one for Date one for Time) and a button are placed. Clicking the button pops up a Calendar control.

Our DateTimeControl is databound like any other control (passing the table and column to be bound), and then the DateTimeControl's DataBind method binds the appropriate pieces to the two text boxes. Regular Expressions and Event Handlers are used to make it all work together. Our DateTimeControl is a very complicated control (and off the top of my head, I don't remember all the events that are used) ... it took one of our brightest developers close to 6 weeks to get it all working right, (although that was back in 2002 when we were all still learning C# ... it probably would take him less time now if he had to do it all over again, which thankfully isn't necessary <g>).

Because it's so complex, I can't post the code for it (and I doubt if our company would let me anyway), but maybe my above explanation of how it works might help?
