Declaration

options | MhtDocumentExporterOptions | A MhtDocumentExporterOptions instance providing options for export. |
Returns
Type | Description |
---|---|
String | A string containing the content in MHT format. |
Remarks
If you operate with a selection range, the GetMhtText method should be enclosed within a DocumentRange.BeginUpdateDocument - DocumentRange.EndUpdateDocument method pair. Otherwise, an incorrect document model might be selected, resulting in an exception “Error: specified document position or range belongs to other document or subdocument” being thrown.
To retrieve the section settings, make sure that the range contains the last section’s paragraph. Otherwise, the section settings are reset to the default.
This code snippet illustrates how to export the selected range to the string in MHT format.
if (this.richEditControl.Document.Selection.Length > 0) {
DevExpress.XtraRichEdit.API.Native.DocumentRange selection = richEditControl.Document.Selection;
DevExpress.XtraRichEdit.API.Native.SubDocument doc = selection.BeginUpdateDocument();
mhtText = doc.GetMhtText(selection);
selection.EndUpdateDocument(doc);
}
else {
mhtText = richEditControl.Document.GetMhtText(richEditControl.Document.Range);
}
