Declaration
Parameters
Name | Type | Description |
---|---|---|
stream | Stream | Specifies the output stream. |
format | DocumentFormat | A DocumentFormat enumeration value that specifies the document’s format. |
Remarks
Take into account the following when you save a document to a stream:
Do not save a workbook to a stream that does not support seek operations. An exception is thrown in this case. Use the System.IO.Stream.CanSeek property to determine if the steam supports seeking.
Do not save a workbook to the same stream from which it was loaded. In this case, document bytes are written to the end of the existing stream and an invalid document is produced.
Use the Workbook.Options.Export property or Workbook.BeforeExport event to specify export options.
// Add a reference to the DevExpress.Docs.dll assembly.
using DevExpress.Spreadsheet;
using System.IO;
// ...
Workbook workbook = new Workbook();
// ...
// Save the document to a stream.
using (FileStream stream = new FileStream("Document.xlsx",
FileMode.Create, FileAccess.ReadWrite))
{
workbook.SaveDocument(stream, DocumentFormat.Xlsx);
}
Calculate Formulas Before Save Operation
The default calculation mode for a Workbook is Manual. This mode implies that the Spreadsheet does not calculate formulas before it saves a document. Call the Workbook.Calculate or Workbook.CalculateFull method to calculate all formulas in the workbook.
