Hi all, I have two typed lists that I'm trying to display in a Master Detail fashion in an Infragistics UltraGrid (although I think Infragistics is probably irrelevant). I can't figure out how to relate the two Typed lists. They have a corresponding PK-FK pair, but (e.g.) the DataSet property is null (and can't be set) so I think they are based on freestanding tables.

I'm using SelfServicing, two class scenario.

I have seen the IRelationPredicateBucket mentioned on the forums but I don't really understand it and my typed lists don't have a GetFieldsInfo() method so that seems like a loser

Any ideas on this?

Thanks,

Alan

Hi,

I think you can add both typedlist to a dataset and add a datarelation (between the two typedlist using the field that related both) to the dataset.

OK, how do you add a typedlist to a dataset? Alan

Hi,

a typedlist is a datatable (by inheritence) so add as you would add a datatable:

youDataSet.Tables.Add(yourTypedList)

Cheers

Oh yes, inheritance, I forgot that. I was trying to find an underlying .DataTable property. Thanks Alan
