SubDocument.GetText(DocumentRange, TextFragmentOptions) Method

Returns the plain text of the specified document range.

Namespace: DevExpress.XtraRichEdit.API.Native

Assembly: DevExpress.RichEdit.v20.2.Core.dll

NuGet Package: DevExpress.RichEdit.Core

NuGet Packages: DevExpress.RichEdit.Core, DevExpress.WindowsDesktop.RichEdit.Core

Declaration

C#

string GetText(
    DocumentRange range,
    TextFragmentOptions getTextOptions
)

VB.NET

Function GetText(
    range As DocumentRange,
    getTextOptions As TextFragmentOptions
) As String

Parameters

Name	Type	Description
range	DocumentRange	A DocumentRange object, specifying the range in the document for which the plain text representation is obtained.
getTextOptions	TextFragmentOptions	A TextFragmentOptions object.

Returns

Type	Description
String	A String value, containing the text of the specified range.

Remarks

Use the GetText method to get a plain text representation of any part of the document. This method overload triggers export-related events as described in the following table:

Event	Description
RichEditControl.BeforeExport	Does not occur.
RichEditControl.AfterExport	Does not occur.

Note

If you operate with a selection range, the GetText method should be combined with 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.

Example

This code snippet finds the first table of contents which is built upon Heading styles using the TOC field and converts it to plain text paragraph by paragraph. The SubDocument.GetText method overload is used for this purpose. It allows you to set the TextFragmentOptions.AllowExtendingDocumentRange option to false to not include the entire TOC when exporting the first paragraph.
