I have an ActiveX control which I wrote that includes a data-bound textbox. Everything works fine when I bind the control to a data source, scroll through records, and so on. However, when I change the string in the textbox, the datasource never goes into an edit mode and the database doesn't change.

I double checked that I'm calling the PropertyChanged in the Property Let routine so I'm pretty sure that's not the problem. When I use a straight VB textbox instead of my control, it works fine so I know the data source and database are set up right (read/write and so on).

Anyone know what the problem is?
