Declaration
procedure cxExportTLToXLSX(const AFileName: string; ATreeList: TcxCustomTreeList; AExpand: Boolean = True; ASaveAll: Boolean = True; AUseNativeFormat: Boolean = True; 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 |
ATreeList | TcxCustomTreeList | The source tree list control. |
AExpand | Boolean | Optional. Specifies if all source tree list nodes are expanded:
|
ASaveAll | Boolean | Optional. Specifies if the procedure exports all available rows:
|
AUseNativeFormat | Boolean | Optional. Specifies if the procedure uses the native data format:
|
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 |
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.

Remarks
If you pass True
as the AUseNativeFormat
parameter, the cxExportTLToXLSX
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 cxExportTLToXLSX
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:
