TcxCustomDataController.FilteredRecordCount Property

Returns the number of records that meet the active filter criteria.

Declaration

property FilteredRecordCount: Integer read;

Property Value

Type	Description
Integer	The number of records that meet the active filter criteria. This property value equals the RecordCount property value if no filter criterion is in effect.

Remarks

You can use FilteredRecordCount and FilteredRecordIndex properties to iterate through all records that meet the active filter criteria.

Code Example

The following code example iterates through all records that meet the active filter criteria and populates a TcxMemo editor with values of the first field in the underlying dataset:

Delphi

uses
  cxGridDBDataDefinitions;  // This unit declares the TcxGridDBDataController class

// ...
  var
    ADataController: TcxGridDBDataController;
    I: Integer;
  begin
    cxMemo1.Lines.Clear;
    ADataController := cxGrid1DBTableView1.DataController;
    for I := 0; to ADataController.FilteredRecordCount - 1 do
      cxMemo1.Lines.Add(ADataController.DisplayTexts[ADataController.FilteredRecordIndex[I], 0]);
  end;

C++

#include "cxGridDBDataDefinitions.hpp"  // This header declares the TcxGridDBDataController class

  // ...
  TcxGridDBDataController *ADataController;
  // ...
  cxMemo1->Lines->Clear();
  ADataController = cxGrid1DBTableView1->DataController;
  for(int i = 0; i < ADataController->FilteredRecordCount; i++)
    cxMemo1->Lines->Add(ADataController->DisplayTexts[ADataController->FilteredRecordIndex[i]][0]);
