cxExportTLToText(string,TcxCustomTreeList,Boolean,Boolean,string,TObject,TEncoding) Method

Exports content of a tree list control to a file in plain text format.

Declaration

procedure cxExportTLToText(const AFileName: string; ATreeList: TcxCustomTreeList; AExpand: Boolean; ASaveAll: Boolean = True; const AFileExt: string = 'txt'; AHandler: TObject = nil; AEncoding: TEncoding = nil);

Parameters

Name	Type	Description
AFileName	string	The absolute or relative path to the resulting TXT file. You can omit the file name extension because it is automatically updated from the AFileExt parameter value.
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 tree list nodes. If False, the procedure exports only visible rows.
ASaveAll	Boolean	Optional. Specifies if the procedure exports all available rows: If True (default), the procedure exports all or only visible rows depending on the AExpand parameter value. If False, the procedure exports only selected rows.
AFileExt	string	Optional. Specifies the file name extension for the resulting TXT file. This parameter value always replaces the file name extension passed as a part of the AFileName parameter value.
AHandler	TObject	Optional. Specifies a handler object that should implement the IcxExportBeforeSave and/or IcxExportProgress interfaces to allow you to perform specific actions before the beginning of 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 (default), the procedure uses the TEncoding.Default encoding.

Remarks

Call the cxExportTLToText procedure to export the tree list control’s content to a file in plain text format. This format stores data without formatting, style, or print layout information. Compared to CSV, exported TXT files are more human-readable.

Code Example

Delphi

uses cxTLExportLink;
// ...
  cxExportTLToText('Departments.txt', cxDBTreeList, True);

C++

#include "cxTLExportLink.hpp"
// ...
  cxExportTLToText("Departments.txt", cxDBTreeList, True);
