cxExportVGToXLSX(string,TcxCustomVerticalGrid,Boolean,Boolean,Integer,string,TObject) Method

Exports content of a vertical grid control to a file in Office Open XML format.

Declaration

procedure cxExportVGToXLSX(const AFileName: string; AVerticalGrid: TcxCustomVerticalGrid; AExpand: Boolean = True; AUseNativeFormat: Boolean = True; ARecordPerBand: Integer = 8; const AFileExt: string = 'xlsx'; AHandler: TObject = nil);

Parameters

Name	Type	Description
AFileName	string	The absolute or relative path to the resulting XLSX file. You can omit the file name extension because it is automatically updated from the AFileExt parameter value.
AVerticalGrid	TcxCustomVerticalGrid	The source vertical grid control.
AExpand	Boolean	Optional. If True, the procedure exports all rows, including collapsed rows. If False, the procedure exports only visible rows.
AUseNativeFormat	Boolean	Optional. Specifies if the procedure uses the native data format: If True (default), the procedure attempts to convert display text of grid cells to their underlying data format (Currency, Date, Time, Numeric, etc.). Refer to the Remarks section for the list of supported in-place editors and corresponding data formats. If False, the procedure exports display text as string values.
ARecordPerBand	Integer	Optional. Specifies the number of records grouped per band in the resulting file.
AFileExt	string	Optional. Specifies the file name extension for the resulting XLSX 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

Remarks

If you pass True as the AUseNativeFormat parameter, the cxExportVGToXLSX procedure attempts to convert display text of a grid item’s cells to their underlying data format (Currency, Date, Time, Numeric, etc.) If you assign an in-place editor to a cell, the export procedure selects the data format according to the following table:

In-place Editor	Data Format
TcxCurrencyEdit	Currency
TcxMaskEdit or TcxCalcEdit	Currency, if the assigned editor is bound to a dataset field whose values are formatted as currency values (TAggregateField.Currency, TBCDField.Currency, TFloatField.Currency, or TFMTBCDField.Currency). Otherwise, the data format is Number.
TcxDateEdit	Date
TcxTimeEdit	Time
TcxSpinEdit	Number

If any other editor is assigned to a cell, the cxExportVGToXLSX procedure exports its display text regardless of the AUseNativeFormat parameter value. If it is impossible to convert display text to the target data type for any reason, the display text is exported as a string.

Note

The listed data formats are used for value conversion only. They do not correspond to cell number formats found in Microsoft Excel®. Populated cells have the General format.

Summary values use the same data type as cell values against which these summaries are calculated if the following conditions are met for the corresponding summary items:

• An empty string is assigned to a summary item’s Format property.
• An OnGetText event handler is not assigned to a summary item.

Code Example

The following code example exports vertical grid content in XLSX format:

Delphi

uses cxExportVGLink;
// ...
  cxExportVGToXLSX('Orders.xlsx', vgOrders);

C++

#include "cxExportVGLink.hpp"
// ...
  cxExportVGToXLSX("Orders.xlsx", vgOrders);

Grid Mode Limitations

The cxExportVGToXLSX procedure exports only the currently cached records when the source vertical grid control is in Grid Mode.
