Hi Mahesh,
this does not work at all for me. Are you sure this is a viable option? The file we are opening is not XAML, it is WordProcessingML.
Displaying an XPS document is easy though. Just add a DocumentViewer to your XAML form, and use two lines of code to display your document:
XpsDocument doc = new XpsDocument("MyDoc.xps", FileAccess.Read);
docViewer1.Document = doc.GetFixedDocumentSequence();
So my best guess is to use Word to save your document as an XPS file, next use that file to display. You can of course write an XSLT to convert the DOCX to XPS, but I dunno how hard that is going to be.
Hope it helps!
