Public Event BeforeImport As BeforeImportEventHandler
The BeforeImport event's data class is BeforeImportEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| DocumentFormat | Gets the format of the document being loaded. |
| Options | Provides access to the importer options. |
The BeforeImport event enables you to adjust the importer options as required.
The following example illustrates how to use the BeforeImport event to specify the location of the loaded HTML file’s external content:
private void richEditControl2_BeforeImport(object sender, BeforeImportEventArgs e) {
if(e.DocumentFormat == DocumentFormat.PlainText) {
((PlainTextDocumentImporterOptions)e.Options).Encoding = cur_Encoding;
}
}
Private Sub richEditControl2_BeforeImport(ByVal sender As Object, ByVal e As BeforeImportEventArgs) Handles richEditControl2.BeforeImport
If e.DocumentFormat = DocumentFormat.PlainText Then
CType(e.Options, PlainTextDocumentImporterOptions).Encoding = cur_Encoding
End If
End Sub
