Set Paragraph Formatting in Word Documents using C# and VB.NET

You can use paragraph formatting to arrange a document's layout. GemBox.Document provides this type of formatting through the ParagraphFormat class.

You have various formatting options at your disposal, like alignment, indentation, spacing, borders, tabs, and many more. The formatting can be set directly on the Paragraph elements by using the Paragraph.ParagraphFormat property.

The example below shows some available paragraph formatting options.

Direct formatting has the highest priority in format resolution. If it's not present, then GemBox.Document can retrieve the formatting from a style applied to an element (ParagraphStyle.ParagraphFormat).

If there is no style, the formatting can be retrieved from the document's default formatting (DocumentModel.DefaultParagraphFormat).

You can read more about this topic in the Style Resolution example on the Formatting properties resolution help page.
