    <p>I have a System.IO.Packaging.Package in memory (it is a WordprocessingDocument) and want to stream it down to browser to save it. The word document has been modified by the MVC-based application and the resulting file has been modified for the current request.</p> <p>I understand the package represents a 'zip' file containing a number of parts. These parts include headers, footers and main body document. I've modified each individually and now want to stream the package back to the user.</p> <p>I can get the individual part streams... package.GetPart(new Uri("/word/document.xml", UriKind.Relative)).GetStream()</p> <p>However I'm missing how to get an output stream on the entire document (package)- without writing to the file system.</p> <p>Thanks in advance</p> <p>No- what I think I need is something like this... I've already read in the template document and made modifications in memory. Now I want to stream a modified document (leaving the template un-touched) back to the user.</p> <pre><code> MemoryStream stream = new MemoryStream(); WordprocessingDocument docOut = WordprocessingDocument.Create( stream, WordprocessingDocumentType.Document); foreach (var part in package.GetParts()) { using (StreamReader streamReader = new StreamReader(part.GetStream())) { PackagePart newPart = docOut.Package.CreatePart( part.Uri, part.ContentType ); using (StreamWriter streamWriter = new StreamWriter(newPart.GetStream(FileMode.Create))) { streamWriter.Write(streamReader.ReadToEnd()); } } } </code></pre> <p>Unfortunately- this produces a 'corrupt' word document... </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
