cxExportTLToCSVStream(TStream,TcxCustomTreeList,Boolean,Boolean,Char,TObject,TEncoding) Method

Exports content of a tree list control to a stream in CSV (comma-separated values) format.

Declaration

procedure cxExportTLToCSVStream(AStream: TStream; ATreeList: TcxCustomTreeList; AExpand: Boolean = True; ASaveAll: Boolean = True; const ASeparator: Char = ','; AHandler: TObject = nil; AEncoding: TEncoding = nil);

Parameters

Name	Type	Description
AStream	TStream	The target stream.
ATreeList	TcxCustomTreeList	The source tree list control.
AExpand	Boolean	Optional. Specifies if all source tree list nodes are expanded: If True (default), the procedure exports all rows, including the rows hidden within collapsed list nodes. If False, the procedure exports only visible nodes.
ASaveAll	Boolean	Optional. Specifies if the procedure exports all available rows: If True (default), the procedure exports all or only visible nodes, depending on the AExpand parameter value. If False, the procedure exports only selected nodes.
ASeparator	Char	Optional. Specifies the character used to delimit exported values in the resulting CSV stream. The default separator character is a comma.
AHandler	TObject	Optional. Specifies a handler object that should implement the IcxExportBeforeSave and/or IcxExportProgress interfaces to allow you to perform specific actions before an export operation and track its progress. Tip Refer to the following topic for detailed information on how to create and use handler objects: How to: Track Data Export Progress
AEncoding	TEncoding	Optional. Specifies the character encoding format of the resulting CSV stream. If nil (in Delphi) or nullptr (in C++Builder) is passed as the AEncoding parameter, the procedure uses the TEncoding.Default encoding.”

Remarks

Call the cxExportTLToCSVStream procedure to export tree list content to a stream in CSV format. In the resulting stream, every plain text line of values separated by commas corresponds to a data record.

Code Example

Delphi

uses cxTLExportLink;
// ...
var
  AStream: TMemoryStream;
begin
  AStream := TMemoryStream.Create;
  cxExportTLToCSVStream(AStream, cxDBTreeList1);
  AStream.SaveToFile('Departments.csv');
  AStream.Free;
end;

C++

#include "cxTLExportLink.hpp"
// ...
  TMemoryStream *AStream = nullptr;
  // ...
  AStream = new TMemoryStream();
  cxExportTLToCSVStream(AStream, cxDBTreeList1);
  AStream->SaveToFile("Departments.csv");
  delete AStream;
