Workbook.LoadDocumentAsync(Stream) Method

Loads a document asynchronously from a stream.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Docs.v19.2.dll

Declaration

C#

public Task<bool> LoadDocumentAsync(
    Stream stream
)

VB.NET

Public Function LoadDocumentAsync(
    stream As Stream
) As Task(Of Boolean)

Parameters

Name	Type	Description
stream	Stream	The stream from which to load a document.

Returns

Type	Description
Task<Boolean>	A Task<TResult> object that return true if the document was loaded successfully; otherwise, false.

Remarks

The Spreadsheet uses the built-in IFormatDetectorService service implementation to detect the format of the loaded document.

If the format detection fails, the Workbook.InvalidFormatException event fires.

Handle the Workbook.DocumentLoaded event to determine when you can safely modify the loaded document.

Important

Take into account the following when you call this method:

• The events fired by this method’s call may occur in a different thread than the target operation.

• The operation is not thread safe (documents should not be accessed simultaneously by different threads). Wait until the operation is completed before working with the document, i.e., use the await operator.
