    <p>Using the MS OpenXml Sdk I have been able to copy a templatestream to a resultstream and append dynamic text(w.p>>w.r>>w.t) at the end of the body using the following code:</p> <pre><code>var templateStream = File.OpenRead(templatePath); templateStream.CopyTo(resultStream); using (var resultPackage = WordprocessingDocument.Open(resultStream, true)) { var document = resultPackage.MainDocumentPart.Document; var body = document.Body; // Add new text. var para = body.AppendChild(new Paragraph()); var run = para.AppendChild(new Run()); run.AppendChild(new Text(firstName)); document.Save(); } </code></pre> <p>My next logical step was to then replace the innertext of a textbox in the resultStream with the firstName as in the code below.</p> <pre><code>// replacing code in using statement from above var document = resultPackage.MainDocumentPart.Document; var textbox = document.Descendants&lt;TextBox&gt;().First(); const string firstNametag = "&lt;&lt;IH.FirstName&gt;&gt;"; if (textbox.InnerText.Contains(firstNametag)) { var textboxContent = textbox.Elements&lt;TextBoxContent&gt;().First(); textboxContent.RemoveAllChildren(); var paragraph = textboxContent.AppendChild(new Paragraph()); var run = paragraph.AppendChild(new Run()); run.AppendChild(new Text(firstName)); } document.Save(); </code></pre> <p>In the first example and with some additional code the result stream is appropriately serialized to a docx and the firstName is appended to the end of the body when viewed in Word. In the second example though the textbox and its contents remain the same even though further examination in the debugger showed the textboxContent's children reflecting the changes made above.</p> <p>I am new to OpenXML development so if there is anything obvious please point it out.</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.
