Two-way Databinding with Custom Control

[Guest]

I've created a custom control that inherits from TextBox. Everything has worked fine up to now. I bind a typed DataSet to my control and when I fill the DataSet, the appropriate record is loaded. I call BeginEdit on the row. Then I change the data in my app, and call EndEdit for the row. But when I look at the DataRow in the debugger, the data is the original data, not the changed data. If I use the default TextBox instead of my own, the new data is put in the DataRow when I call EndEdit and the database updates correctly. HasChanges knows that something has changed. There is a current row and an original row in the DataSet. I'm obviously missing something in my custom control but I can't figure out what. Does anybody have a clue?

I have exactly the same problem, only I use Infragistic's UltraTextEditor
instead of Microsoft's TextBox as the view, and Borland's ECO
ReferenceHandle instead of Microsoft's DataSet as the model.

So, if you found the solution, please post it here (or in the
microsoft.public.dotnet.framework.windowsforms.databinding NG).
