I'm populating a Infragistics combo box using SF Population methods and it works fine. When I blank out the field I get a error: Conversion from type 'DBNull' to type 'String' is not valid. I have set the 'Nullable' property to 'False' but it doesn't seem to make a difference.  When I use a SF ComboBox it works fine.

Any Ideas on how to resolve this issue? Is this a Infragistics problem?

Thanks

Yes, I can use the control with a BBS but there is no biniding properties like the other controls for Business Object, binding field, state etc...  Perhaps I'm missing something?

Trent,

I emailed you a small sample application that demonstrates the error on the ComboBoxEdit.

Ah, yes, the data source for the grid that drops down can be bound to the BBS, but you're right, the IBusinessBindable is not implemented for the fields that you normally use to bind to a business object.  However, any control can bind to a BBS using the DataBindings type editor that you find in the "Data" category.
