Problem setting paragraph style to custom style

I am having difficulty changing the style of paragraphs in a document to a custom style.

I have attached the project, which shows the particular issue. I am expecting the fonts to be changed to match the fonts as configured in “Create style” through MS Word. It works fine when selecting the style in Word itself.

The code I am running at the minute is paragraph.StyleName = “StyleName”, which sets the colour, justification, etc. properly - the same as when I run the below

var style = doc.Styles[“StyleName”];

paragraph.Style = style;

However, the only way I seem to be able to set the font style I want (expect!), i.e size, bold, italic, underline, etc., is by getting a list of the runs from the paragraph and looping over them setting .Font.Size, .Font.Bold, .Font.Italic, etc., to match that of the in style.Font - which is a bit much! Setting the paragraph style should pull the font settings from the style and set them appropriately… As is done in MS Word.

Am I doing it right or is this a bug? If so, is there an easier workaround?

Hi Rob,

Thanks for your patience. It is to inform you that our product team has completed the work on issue (WORDSNET-13395) and has come to a conclusion that this issue and the undesired behavior you're observing is actually not a bug in Aspose.Words. So, we have closed this issue as 'Not a Bug'.

The paragraphs contains runs with direct formatting. So, upon setting ParagraphFormat.StyleName you have to clear run formatting as shown below:

var doc = new Document(MyDir + "ParagraphStyleIssue.docx");

foreach (Paragraph para in doc.GetChildNodes(NodeType.Paragraph, true))


para.ParagraphFormat.StyleName = "ParagraphStyle";

foreach (Run run in para.Runs)






var output = MyDir + @"Out.docx";


doc.Save(output, SaveFormat.Docx);
