SubDocument.GetRtfText(DocumentRange, RtfDocumentExporterOptions) Method

Gets the formatted string of the text contained in the specified range.

Namespace: DevExpress.XtraRichEdit.API.Native

Assembly: DevExpress.RichEdit.v19.1.Core.dll

Declaration

C#

string GetRtfText(
    DocumentRange range,
    RtfDocumentExporterOptions options
)

VB.NET

Function GetRtfText(
    range As DocumentRange,
    options As RtfDocumentExporterOptions
) As String

Parameters

Name	Type	Description
range	DocumentRange	A DocumentRange object representing a text range in the document.
options	RtfDocumentExporterOptions	An RtfDocumentExporterOptions instance providing options for export.

Returns

Type	Description
String	A string of RTF text.

Remarks

If you operate with a selection range, the GetRtfText 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 section’s last paragraph. Otherwise, the section settings are reset to the default.

Example

This code snippet illustrates how to export the selected range to the string in RTF format.
