Namespace: DevExpress.XtraRichEdit.API.Native.Implementation

Assembly: DevExpress.RichEdit.v22.1.Core.dll

Declaration

public bool AllowExtendingDocumentRange { get; set; }

Property Value

Type Description
Boolean

true to permit extending the document range; otherwise false.

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.

document.LoadDocument("SampleTOC.docx", DocumentFormat.OpenXml)
Dim plainText As String = String.Empty

For Each item As Field In document.Fields
    Dim fieldCode As String = document.GetText(item.CodeRange)
    Dim fieldParts() As String = fieldCode.Split(" "c)
    If fieldParts(0).Trim() = "TOC" AndAlso fieldParts(1).Trim() = "\h" Then
        Dim options As New DevExpress.XtraRichEdit.API.Native.Implementation.TextFragmentOptions()
        options.AllowExtendingDocumentRange = False
        For Each par As Paragraph In document.Paragraphs.Get(item.ResultRange)
            plainText &= document.GetText(par.Range, options)
            plainText &= Environment.NewLine
        Next par
    End If
Next item

DevExpress.XtraEditors.XtraMessageBox.SmartTextWrap = False
DevExpress.XtraEditors.XtraMessageBox.Show(plainText)
