TextFragmentOptions.AllowExtendingDocumentRange Property

Specifies whether or not a document range may be extended to include the entire field instead of only part of a field.

Namespace: DevExpress.XtraRichEdit.API.Native.Implementation

Assembly: DevExpress.RichEdit.v23.1.Core.dll

NuGet Package: DevExpress.RichEdit.Core


public bool AllowExtendingDocumentRange { get; set; }

Property Value

Type Description

true to permit extending the document range; otherwise false.


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.

View Example

using DevExpress.XtraRichEdit.API.Native.Implementation;
using DevExpress.XtraEditors;

string plainText = String.Empty;

foreach (Field item in document.Fields) {
    string fieldCode = document.GetText(item.CodeRange);
    string[] fieldParts = fieldCode.Split(' ');
    if (fieldParts[0].Trim() == "TOC" && fieldParts[1].Trim() == "\\h") {
        TextFragmentOptions options = 
            new TextFragmentOptions();
        options.AllowExtendingDocumentRange = false;
        foreach (Paragraph par in document.Paragraphs.Get(item.ResultRange)) {
            plainText += document.GetText(par.Range, options);
            plainText += Environment.NewLine;

XtraMessageBox.SmartTextWrap = false;
