How to Filter a Collection
27 Mar 2018 / 1 minute to read
To add a filter condition, add a RecordFilterDescriptor to the Engine.TableDescriptor.RecordFilters collection. The constructor on the RecordFilterDescription takes an expression, “[D] LIKE ‘d1’”. This expression will be True only for those items in the list where the string property D has the value d1. Here are some other valid expressions where B is an integer property:
-
“[B] = 5 OR [B] < 0”
-
“[D] LIKE ‘d1’ OR [B] = 2”
// Filter on [D] = d1
RecordFilterDescriptor recordFilterDescriptor = new RecordFilterDescriptor("[D] LIKE 'd1'");
this.groupingEngine.TableDescriptor.RecordFilters.Add(recordFilterDescriptor);
' Filter on [D] = d1
Dim recordFilterDescriptor As New RecordFilterDescriptor("[D] LIKE 'd1'")
Me.groupingEngine.TableDescriptor.RecordFilters.Add(recordFilterDescriptor)
