Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Docs.v25.1.dll

NuGet Package: DevExpress.Document.Processor

Declaration

C#

public event EventHandler<BeforeEncodingDetectionEventArgs> BeforeEncodingDetection

VB.NET

Public Event BeforeEncodingDetection As EventHandler(Of BeforeEncodingDetectionEventArgs)

Event Data

The BeforeEncodingDetection event's data class is BeforeEncodingDetectionEventArgs. The following properties provide information specific to this event:

Property	Description
Encoding	Gets or sets the document encoding.
Handled	Gets or sets whether the event is handled.
Stream	Obtains a stream with document data.

Remarks

The BeforeEncodingDetection event is raised when the spreadsheet attempts to detect encoding of the CSV or TXT text being imported. Handle this event to specify a custom encoding instead of the automatically detected encoding.

The event fires only if the TxtDocumentImporterOptions.AutoDetectEncoding or CsvDocumentImporterOptions.AutoDetectEncoding property is set to true.

The code sample below shows how to handle the event to specify the encoding:

C#

private void Workbook_BeforeEncodingDetection(object? sender, BeforeEncodingDetectionEventArgs e)
{
    e.Encoding = Encoding.UTF8;
    e.Handled = true;
}

VB.NET

Private Sub Workbook_BeforeEncodingDetection(ByVal sender As Object, ByVal e As BeforeEncodingDetectionEventArgs)
  e.Encoding = Encoding.UTF8
  e.Handled = True
End Sub
