Hello,
You can add a sorting clause in the FetchTypedView Method.
In Vb it can be done as it where "MyEntityFields.MyField" is the fields on which you want to sort :
Dim sorterChoice As ISortExpression = New SortExpression( _
New SortClause(MyEntityFields.MyField, Nothing, SortOperator.Descending))
myTypedList.Fill(0, sorterChoice, True, bucket)
If you don't have predicate you could let bucket at nothing.
After you can bind your typedlist to your dropdown.
Althought in the datasource you can use the property "SorterToUse" in the llbldatasource like that :
Me.llblDataSource.SorterToUse = New SortExpression(EntityFields.Field Or SortDirection.Descending)
but in two case you have to write code behind.
