Provides access to the list of filtered records.

Declaration

property FilterList: TdxIntegerList read;

Property Value

Type	Description
TdxIntegerList	The list of filtered records (as record indexes).

Remarks

The list accessible through the FilterList property maintains the list of filtered records when the ProgrammedFilter property is set to True.

Code Example: Populate Filtered Record Lists

The following code example populates the list of filtered records accessible through the FilterList property:

Delphi

var
  AGroupIDField: TField;
begin
  dxMemData1.ProgrammedFilter := True;
  AGroupIDField := dxMemData1.FieldByName('GroupID');
  while not dxMemData1.Eof do
  begin
    if AGroupIDField.AsInteger = 1 then
      dxMemData1.FilterList.Add(dxMemData1.RecNo);
    dxMemData1.Next;
  end;
  dxMemData1.Filtered := True;
end;

C++

  TField *AGroupIDField;
  // ...
  dxMemData1->ProgrammedFilter = true;
  AGroupIDField = dxMemData1->FieldByName("GroupID");
  do
  {
    if(AGroupIDField->AsInteger == 1)
      dxMemData1->FilterList->Add(dxMemData1->RecNo);
    dxMemData1->Next();
  } while(!dxMemData1->Eof);
  dxMemData1->Filtered = true;
