Related API Members

The following members return ParagraphPropertiesBase objects:

• Document.DefaultParagraphProperties
• ListLevel.ParagraphProperties

Remarks

Use the SubDocument.BeginUpdateParagraphs(DocumentRange) – SubDocument.EndUpdateParagraphs(ParagraphProperties) method pair to change paragraph options.

Example

The following code snippet changes paragraph formatting in code:

C#

using DevExpress.XtraRichEdit.API.Native;
using DevExpress.Office.Utils;

using (var wordProcessor = new RicheditDocumentServer())
{
    // Access a document.
    Document document = wordProcessor.Document;

    // Start to edit the document.
    document.BeginUpdate();

    // Append text to the document.
    document.AppendText("Modified Paragraph\nNormal\nNormal");

    // Finalize document modification.
    document.EndUpdate();

    // Access the first paragraph's range
    DocumentRange range = document.Paragraphs[0].Range;

    // Start to edit the paragraph.
    ParagraphProperties pp = document.BeginUpdateParagraphs(range);

    // Specify the paragraph's alignment.
    pp.Alignment = ParagraphAlignment.Center;

    // Specify the paragraph's line spacing.
    pp.LineSpacingType = ParagraphLineSpacing.Multiple;
    pp.LineSpacingMultiplier = 3;

    // Set the paragraph's left indent to 0.5 document unit.
    // Default unit is 1/300 of an inch (a document unit).
    pp.LeftIndent = Units.InchesToDocumentsF(0.5f);

    // Start to modify tab stops in the paragraph.
    TabInfoCollection tbiColl = pp.BeginUpdateTabs(true);

    // Create a new tab stop for the paragraph.
    TabInfo tbi = TabInfo();

    // Specify the tab stop's alignment type.
    tbi.Alignment = TabAlignmentType.Center;

    // Set the tab stop position to 1.5 document unit.
    tbi.Position = Units.InchesToDocumentsF(1.5f);

    // Add the tab stop to the collection of tab stops.
    tbiColl.Add(tbi);

    // Finalize tab stop modification.
    pp.EndUpdateTabs(tbiColl);

    // Finalize the paragraph edit operation.
    document.EndUpdateParagraphs(pp);
}
