Workbook.LoadDocument(Byte[]) Method

Loads a document from a byte array.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Docs.v19.1.dll

Declaration

C#

public bool LoadDocument(
    byte[] buffer
)

VB.NET

Public Function LoadDocument(
    buffer As Byte()
) As Boolean

Parameters

Name	Type	Description
buffer	Byte[]	A byte array that contains document data.

Returns

Type	Description
Boolean	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.

You can use the current LoadDocument method overload to load a workbook stored in an external database. Refer to the How to: Store a Workbook in the Database document for more information.

C#

// Add a reference to the DevExpress.Docs.dll assembly.
using DevExpress.Spreadsheet;
// ...

Workbook workbook = new Workbook();

// Save a document to a byte array to store it in a database.
byte[] docBytes = workbook.SaveDocument(DocumentFormat.Xlsx);

// ...

// Load the saved document from a byte array into the Workbook instance.
workbook.LoadDocument(docBytes);

VB.NET

' Add a reference to the DevExpress.Docs.dll assembly.
Imports DevExpress.Spreadsheet
' ...

Dim workbook As New Workbook()

' Save a document to a byte array to store it in a database.
Dim docBytes() As Byte = workbook.SaveDocument(DocumentFormat.Xlsx)

' ...

' Load the saved document from a byte array into the Workbook instance.
workbook.LoadDocument(docBytes)
