Declaration

procedure ExportGridToHTMLStream(AStream: TStream; AGrid: TcxGrid; AExpand: Boolean = True; ASaveAll: Boolean = True; AHandler: TObject = nil);

Parameters

Name	Type	Description
AStream	TStream	The target stream.
AGrid	TcxGrid	The source data grid control.
AExpand	Boolean	Optional. 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. If True, the procedure exports all or visible rows, depending on the AExpand parameter value. If False, the procedure exports only selected rows. In grid mode, the ASaveAll parameter value is ignored.
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. Refer to the following topic for detailed information on how to create and use handler objects: How to: Track Data Export Progress.

Remarks

The ExportGridToHTMLStream procedure creates image files to display cell images as inline images in the output HTML stream. Use the cxExportGraphicClass global constant to change the image container class for export image generation.

Example

Example

The following code example exports grid content to a file in HTML format with expanded detail pages:

Delphi

var
  AStream: TMemoryStream;
begin
  AStream := TMemoryStream.Create;
  ExportGridToHTMLStream(AStream, cxGrid1, True);
  AStream.SaveToFile('Employees.html');
  AStream.Free;
end;

C++

  TMemoryStream *AStream = nullptr;
  // ...
  AStream = new TMemoryStream();
  ExportGridToHTMLStream(AStream, cxGrid1, true);
  AStream->SaveToFile("Employees.html");
  delete AStream;
