NotSupportedException when using AddNew() method
posted

I am trying to add a row to my UltraCombo programmatically and I get an exception 

I have read about the other issues people have add when not having the allownewrow setting set to True, but that has not helped me. I am not sure if it is the underlying datasource based on the exception.

Here is my code for adding the row:

                band0.Override.AllowAddNew = AllowAddNew.Yes;
                UltraGridRow urow = band0.AddNew();

 

Here is my exception:

System.NotSupportedException was unhandled by user code
  Message="Update method not supported"
  Source="Infragistics2.Win.UltraWinGrid.v8.1"
  InnerException:

    I don't think that this is actually supported for the UltraCombo; looking at the code it seems that when you do this there is a specific check to make sure that it is an UltraGrid (and not an UltraGridBase-derived object, such as the combo).  You should probably add the new row to the underlying data source instead.
