Unable to set multiline while editing Word ContentControl using SDTElement

[SATISD9XParticipant]

The following code sets the text inside the ContentControl from a Word Template. The ContentControls are iterated through WordProcessingDocument objects SDTElement’s SDTAlias value and if found set the appropriate desired text/date etc.

	    byte[] byteArray = File.ReadAllBytes("Test.docx");
            using (MemoryStream mem = new MemoryStream())
            {
                mem.Write(byteArray, 0, (int)byteArray.Length);
                using (WordprocessingDocument wordDoc =
                    WordprocessingDocument.Open(mem, true))
                {
                    MainDocumentPart mainPart = wordDoc.MainDocumentPart;

                    foreach (SdtElement sdtEle in mainPart.Document.Descendants<SdtElement>())
                    {
                        string sdType = sdtEle.GetType().Name;
                        SdtAlias alias = sdtEle.Descendants<SdtAlias>().FirstOrDefault();
                        string sdtTitle = alias.Val.Value;
                        Run run = new Run();

                        if (alias != null)
                        {
                            // delete all paragraph of the sdt
                            sdtEle.Descendants<Paragraph>().ToList().ForEach(p => p.Remove());
                            
                            switch (alias.Val.Value)
                            {
                                case "TOPIC":
                                    var t = sdtEle.Descendants<Text>().FirstOrDefault();
                                    t.Text = "Text for Via Fedex1";
                                    break;

                                case "DATE":
                                    var pd = sdtEle.Descendants<Text>().FirstOrDefault();
                                    pd.Text = "02/08/2017";
                                    break;

                                case "ADDRESS":
                                    if(sdType.ToUpper() == "SDTRUN")
                                    { 
                                        var sca = sdtEle.Descendants<Text>().FirstOrDefault();
                                        //sca.Text = "ABC" + Environment.NewLine + "XYZ";
                                        
                                        run.AppendChild(new Text("ABC"));
                                        run.AppendChild(new Break());
                                        run.AppendChild(new Text("XYZ"));
                                        
                                    }
                                    else if(sdType.ToUpper() == "SDTBLOCK")
                                    {
                                        var t = sdtEle.Descendants<Text>().FirstOrDefault();
                                    	t.Text = "Another Address";
                                    	break;

                                        
                                    }
                                    break;

                            }

                        }
                    }

                }
                
                using (FileStream fileStream = new FileStream("Test1.docx",
                    System.IO.FileMode.CreateNew))
                {
                    mem.WriteTo(fileStream);
                }

But in the above code, the multiline is NOT set to ContentControl (ADDRESS in above code) using the below lines
//sca.Text = “ABC” + Environment.NewLine + “XYZ”;
OR
//run.AppendChild(new Text(“ABC”));
//run.AppendChild(new Break());
//run.AppendChild(new Text(“XYZ”));

Please assist.

Hi,

Looking at your code, nothing looks incorrect to me, but I normally use LINQ to XML to access and manipulate content instead of the strongly-typed object model, so I may be missing something.

In general, if you need to generate documents from data, I recommend using the DocumentAssembler module in Open-Xml-PowerTools.

http://www.ericwhite.com/blog/blog/documentassembler-developer-center/

Watch those videos – you can do document assembly without writing code.

If you go down that path, and if you continue to use the strongly-typed object model, I recommend closing and opening the document any time you switch between using LINQ to XML and the strongly-typed object model.

Best, Eric
