Tim, in another post, Trent mentioned that UltraCombo is derived from grid and you should use Business Binding Solution.



Hope I'm right quoting Trent!

I just want to clarify.

The error is on the SF UltraComboEdit, and not the UltraCombo. (I would like to use the UltraCombo but you haven't wrapped it yet). Sorry for the confusion.

Hmmm....I will have to look into it.  We recently modified the SF combobox to allow multiple-columns in the drop down which was one of the major reasons to use the Infragistics.  The Infragistics combo ultimately uses a grid in the drop-down so it created a bit more overhead and has some of the funny things you run into with grids in general.  However, that being said, it is a good control so don't get me wrong, but as for the error, I will have to look into it.  Sorry for the round-a-bout answer

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

Tim
