ExportGridToTextStream(TStream,TcxGrid,Boolean,Boolean,string,string,string,TObject,TEncoding) Method

Exports content of a data grid control to a stream in plain text format.

Declaration

procedure ExportGridToTextStream(AStream: TStream; AGrid: TcxGrid; AExpand: Boolean; ASaveAll: Boolean; const ASeparator: string; const ABeginString: string; const AEndString: string; AHandler: TObject = nil; AEncoding: TEncoding = nil);

Parameters

Name	Type	Description
AStream	TStream	The target stream.
AGrid	TcxGrid	The source data grid control.
AExpand	Boolean	If True, the procedure exports all rows, including the rows hidden within collapsed group rows and master rows. 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. The ASaveAll parameter value is ignored in grid mode.
ASeparator	string	Specifies the string used to delimit exported values in the resulting plain text stream.
ABeginString	string	Specifies the prefix string for every cell value.
AEndString	string	Specifies the postfix string for every cell 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 ExportGridToTextStream procedure to export the data grid control’s content to a stream in plain text format. This format stores data without formatting, style, or print layout information. Compared to CSV, the plain text format is more human-readable.

Code Example

The following code example exports grid content to a stream in plain text format when the ABeginString parameter is set to '|':

Delphi

uses cxGridExportLink;
// ...
var
  AStream: TMemoryStream;
begin
  AStream := TMemoryStream.Create;
  ExportGridToTextStream(AStream, cxGrid1, False, True, '', '|', '', 'txt');
  AStream.SaveToFile('Employees.txt');
  AStream.Free;
end;

C++

#include "cxGridExportLink.hpp"
// ...
  TMemoryStream *AStream = nullptr;
  // ...
  AStream = new TMemoryStream();
  ExportGridToTextStream(AStream, cxGrid1, false, true, "", "|", "", "txt");
  AStream->SaveToFile("Employees.txt");
  delete AStream;
