I have also went into the ListView properties and set the Columns Collection to one column called colPrimary as the image shows. I set the PopulationDataSource to OrdersBo and the Method to FillByParentPrimaryKey(Int32), display fields to {0} or_pk, columns to formattedString and {0} and finally tag field to or_pk.
When I run the form I get what is shown in the SimpleListView image. What am I missing? It maybe that I have a parent child defined and then I am using the Fillbyparentprimarykey method but I am not sure.
TIA.
