How to keep style on open xml documents - c#

I am using open XML(Microsoft Word - .docx) as a file template to automatically generate other documents. In the template document I have defined content controls, and I have written code to replace content in these content controls.
The content is replaced and the documents are generated, but I am struggling with keeping the style. In Word, when inspecting properties of the content control, I have checked the checbox for "Use a style to format text into the empty control: style", and also checked for "Remove content controls when content are edited". This doesn't seem to have any impact when documents are generated by code.
This is my code (which a community member here was kind enough to help with) for replacing the data in the content controls. Any ideas what I should do in order to keep the formatting? The formatting is simple text formatting, like size and font. Please advice:
private static void ReplaceTags(MainDocumentPart mainPart, string tagName, string tagValue)
{
//grab all the tag fields
var tagFields = mainPart.Document.Body.Descendants<SdtBlock>().Where
(r => r.SdtProperties.GetFirstChild<Tag>().Val == tagName);
foreach (var field in tagFields)
{
//remove all paragraphs from the content block
field.SdtContentBlock.RemoveAllChildren<DocumentFormat.OpenXml.Wordprocessing.Paragraph>();
//create a new paragraph containing a run and a text element
var newParagraph = new DocumentFormat.OpenXml.Wordprocessing.Paragraph();
var newRun = new DocumentFormat.OpenXml.Wordprocessing.Run();
var newText = new DocumentFormat.OpenXml.Wordprocessing.Text(tagValue);
newRun.Append(newText);
newParagraph.Append(newRun);
//add the new paragraph to the content block
field.SdtContentBlock.Append(newParagraph);
}
}

When you assign a style to the content control a new RunProperties element is added under the SdtProperties. For example, if I assign a new style called Style1 I can see the following XML is generated:
<w:sdt>
<w:sdtPr>
<w:rPr>
<w:rStyle w:val="Style1" />
</w:rPr>
<w:alias w:val="LastName" />
<w:tag w:val="LastName" />
....
You need to grab this value and assign it to the new Paragraph you are creating, add the Paragraph at the same level as the SdtBlock and then remove the SdtBlock which is what Word does when you select the "Remove content control when contents are edited" option. The RunProperties are the <w:rPr> element. The following should do what you're after.
private static void ReplaceTags(MainDocumentPart mainPart, string tagName, string tagValue)
{
//grab all the tag fields
IEnumerable<SdtBlock> tagFields = mainPart.Document.Body.Descendants<SdtBlock>().Where
(r => r.SdtProperties.GetFirstChild<Tag>().Val == tagName);
foreach (var field in tagFields)
{
//grab the RunProperties from the SdtBlcok
RunProperties runProp = field.SdtProperties.GetFirstChild<RunProperties>();
//create a new paragraph containing a run and a text element
Paragraph newParagraph = new Paragraph();
Run newRun = new Run();
if (runProp != null)
{
//assign the RunProperties to our new run
newRun.Append(runProp.CloneNode(true));
}
Text newText = new Text(tagValue);
newRun.Append(newText);
newParagraph.Append(newRun);
//insert the new paragraph before the field we're going to remove
field.Parent.InsertBefore(newParagraph, field);
//remove the SdtBlock to mimic the Remove content control when contents are edited option
field.Remove();
}
}

Search Word Document and hide range where Style.localName = "MyStyle"

I have a lot of Word documents where I need to hide text witch is formatted with a custom Word.Style type.
I’m using C# in a Windows Form and I’ve tried to open the Word documents one by one and go through all paragraphs. I then cast the paragraph style to a style object and from this I get the paragraphs Style localname.
Then if this paragraphs local style name matches one that I need to hide, then I try to take the paragraps.Range, select it, and set it to range.Font.Hidden = 1 I then try to save the document, but it document dosen’t change, so text formatted with my custom style does not change.
I've tried this so far:
using Word = Microsoft.Office.Interop.Word;
Word.Application wordApp = new Word.Application();
private void buttonOpenMany_Click(object sender, EventArgs e)
{
List<string> Styles = new List<string>();
Styles.Add("MyStyle1");
Styles.Add("MyStyle2");
Styles.Add("MyStyle3");
foreach (var item in Directory.GetFiles(textBoxWordFolder.Text,"*.docx"))
{
HideByStyleName(item, Styles);
}
MessageBox.Show("Done");
}
void HideByStyleName(string WordFile, List<string> StylesToHide)
{
wordApp.Documents.Open(WordFile);
Word.Document document = wordApp.ActiveDocument;
Word.Range rng = document.Content;
foreach (Word.Paragraph paragraph in document.Paragraphs)
{
Object styleobject = paragraph.get_Style();
string stylename = ((Word.Style)styleobject).NameLocal;
foreach (var style in StylesToHide)
{
if (stylename == style)
{
Word.Range range = paragraph.Range;
range.Select();
range.Font.Hidden = 1;
}
}
}
document.SaveAs2(WordFile);
document.Close();
}
I’ve also tried to use Range.Find.Execute but are having a hard time to figure out how to use this to find text where the Style.NameLocal =”MyCustomStyle1” And also who to replace this found range with Hidden text. Hope anyone have some input or guides.
Thank you and best regards

How to query the Base Paragraph element position? in order to add Link Annotation without saving the file

I'm creating a simple PDF file with some text and an hyperlink attached to the that text:
Document pdfDocument = new Document();
Page pdfPage = pdfDocument.Pages.Add();
TextFragment textFragment = new TextFragment("My Text");
Table table = new Table();
Row row = table.Rows.Add();
Cell cell = row.Cells.Add();
cell.Paragraphs.Add(textFragment);
pdfPage.Paragraphs.Add(table);
LinkAnnotation link = new LinkAnnotation(pdfPage, textFragment.Rectangle); //[Before Save]textFragment.Rectangle: 0,0,35.56,10
link.Action = new GoToURIAction("Link1 before save");
pdfPage.Annotations.Add(link);
pdfDocument.Save(dataDir + "SimplePDFWithLink.pdf");
The problem is that the link annotation is being assign to the before save rectangle [0,0,33.56,10] at the bottom of the screen where's the textFragment is being added to a different rectangle (I can't set here the Position property because I don't know it, it is relative to the cell's table).
In order to solve this I've tried saving the page and only then searching the textFragment using TextFragmentAbsorber
pdfDocument.Save(dataDir + "SimplePDFWithLink.pdf");
//[After Save]textFragment.Rectangle: 0,0,90,770
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber();
pdfPage.Accept(textFragmentAbsorber);
foreach (TextFragment absorbedTextFragment in textFragmentAbsorber.TextFragments)
{
link = new LinkAnnotation(pdfPage, absorbedTextFragment.Rectangle);
link.Action = new GoToURIAction("Link 2 after save");
pdfPage.Annotations.Add(link);
}
pdfDocument.Save(dataDir + "SimplePDFWithLink.pdf");
My Question:
Is is possible to add a simple link to a TextFragment (which is BaseParagraph not StructureElement) without saving the document first?
Here is a simple demo of the outcome, you can see that before saving the document the link is added to the left bottom of the document instead of the text rectangle:
Update:
If I specify the TextFragment's Position value with some arbitrary values, the link is then added exactly to the text, but I don't know what will be the Position value of the element because it being built dynamically using a Table.
Working with TextFragment and TextSegment does work and adds the link without pre-saving the file:
TextFragment textFragment = new TextFragment("My Text");
TextSegment textSegment = new TextSegment("Link to File");
textSegment.Hyperlink = new Aspose.Pdf.WebHyperlink("www.google.com");
textFragment.Segments.Add(textSegment);
It is worth to mention it is works well when linking to a file on the user's file-system like:
textSegment.Hyperlink = new Aspose.Pdf.WebHyperlink("Files\foo.png");

RichTextBox links appearing on same position

I have been able to get links appearing in my RichTextbox. The first entry is correct but when I try appending a new line that also contains a link, the first entry is in the same position as the new link. When clicking on the link it retains it's first entries hyperlink.
I want each line to have it's own hyperlink (where it's underlined)
Code used to append a Link
public void AppendLink(string text, string linkText)
{
LinkLabel link = new LinkLabel();
link.Text = text;
link.LinkClicked += new LinkLabelLinkClickedEventHandler(this.link_LinkClicked);
LinkLabel.Link data = new LinkLabel.Link();
data.LinkData = linkText;
link.Links.Add(data);
link.Location = this.logTextBox.GetPositionFromCharIndex(this.logTextBox.TextLength);
this.logTextBox.Controls.Add(link);
logTextBox.SelectionFont = UNDERLINE_FONT;
this.logTextBox.AppendText(s);
}
Called using this
AppendLogLine("Sealed ");
AppendLink(itemName, GetItemLink(itemName));
AppendLog(" is an unknown item. Keeping.");
Append Log and AppendLogLine does the same as AppendLink just doesn't create a link and uses a different Font

Replace text in Word with text from C# form

I'm trying to make an application in C#. When pressing a radio button, I'd like to open a Microsoft Word document (an invoice) and replace some text with text from my Form. The Word documents also contains some textboxes with text.
I've tried to implement the code written in this link Word Automation Find and Replace not including Text Boxes but when I press the radio button, a window appears asking for "the encoding that makes the document readable" and then the Word document opens and it's full of black triangles and other things instead of my initial template for the invoice.
How my invoice looks after:
Here is what I've tried:
string documentLocation = #"C:\\Documents\\Visual Studio 2015\\Project\\Invoice.doc";
private void yes_radioBtn_CheckedChanged(object sender, EventArgs e)
{
FindReplace(documentLocation, "HotelName", "MyHotelName");
Process process = new Process();
process.StartInfo.FileName = documentLocation;
process.Start();
}
private void FindReplace(string documentLocation, string findText, string replaceText)
{
var app = new Microsoft.Office.Interop.Word.Application();
var doc = app.Documents.Open(documentLocation);
var range = doc.Range();
range.Find.Execute(FindText: findText, Replace: WdReplace.wdReplaceAll, ReplaceWith: replaceText);
var shapes = doc.Shapes;
foreach (Shape shape in shapes)
{
var initialText = shape.TextFrame.TextRange.Text;
var resultingText = initialText.Replace(findText, replaceText);
shape.TextFrame.TextRange.Text = resultingText;
}
doc.Save();
doc.Close();
Marshal.ReleaseComObject(app);
}
So if your word template is the same each time you essentially
Copy The Template
Work On The Template
Save In Desired Format
Delete Template Copy
Each of the sections that you are replacing within your word document you have to insert a bookmark for that location (easiest way to input text in an area).
I always create a function to accomplish this, and I end up passing in the path - as well as all of the text to replace my in-document bookmarks. The function call can get long sometimes, but it works for me.
Application app = new Application();
Document doc = app.Documents.Open("sDocumentCopyPath.docx");
if (doc.Bookmarks.Exists("bookmark_1"))
{
object oBookMark = "bookmark_1";
doc.Bookmarks.get_Item(ref oBookMark).Range.Text = My Text To Replace bookmark_1;
}
if (doc.Bookmarks.Exists("bookmark_2"))
{
object oBookMark = "bookmark_2";
doc.Bookmarks.get_Item(ref oBookMark).Range.Text = My Text To Replace bookmark_2;
}
doc.ExportAsFixedFormat("myNewPdf.pdf", WdExportFormat.wdExportFormatPDF);
((_Document)doc).Close();
((_Application)app).Quit();
This code should get you up and running unless you want to pass in all the values into a function.
EDIT: If you need more examples I'm working on a blog post as well, so I have a lot more detail if this wasn't clear enough for your use case.

underline portion of text using iTextSharp

I have an application that uses itextsharp to fill PDF form fields.
One of these fields has some text with tags. For example:
<U>This text should be underlined</>.
I'd like that the text closed in .. has to be underlined.
How could I do that?
How could I approch it with HTMLWorker for example?
Here's the portion of code where I write my description:
for (int i = 0; i < linesDescription.Count; i++)
{
int count = linesDescription[i].Count();
int countTrim = linesDescription[i].Trim().Count();
Chunk cnk = new Chunk(linesDescription[i] + GeneralPurpose.ReturnChar, TextStyle);
if (firstOpe && i > MaxLinePerPage - 1)
LongDescWrapped_dt_extra.Add(cnk);
else
LongDescWrapped_dt.Add(cnk);
}
Ordinary text fields do not support rich text. If you want the fields to remain interactive, you will need RichText fields. These are fields that are flagged in a way that they accept an RV value. This is explained here: Set different parts of a form field to have different fonts using iTextSharp (Note that I didn't succeed in getting this to work, but you may have better luck.)
If it is OK for you to flatten the form (i.e. remove all interactivity), please take a look at the FillWithUnderline example:
public void manipulatePdf(String src, String dest) throws DocumentException, IOException {
PdfReader reader = new PdfReader(src);
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(dest));
stamper.setFormFlattening(true);
AcroFields form = stamper.getAcroFields();
FieldPosition pos = form.getFieldPositions("Name").get(0);
ColumnText ct = new ColumnText(stamper.getOverContent(pos.page));
ct.setSimpleColumn(pos.position);
ElementList elements = XMLWorkerHelper.parseToElementList("<div>Bruno <u>Lowagie</u></div>", null);
for (Element element : elements) {
ct.addElement(element);
}
ct.go();
stamper.close();
}
In this example, we don't fill out the field, but we get the fields position (a page number and a rectangle). We then use ColumnText to add content at this position. As we are inputting HTML, we use XML Worker to parse the HTML into iText objects that we can add to the ColumnText object.
This is a Java example, but it should be easy to port this to C# if you know how to code in C# (which I don't).
You can trythis
Chunk chunk = new Chunk("Underlined TExt", FontFactory.GetFont(FontFactory.TIMES_ROMAN, 12.0f, iTextSharp.text.Font.BOLD | iTextSharp.text.Font.UNDERLINE));
Paragraph reportHeadline = new Paragraph(chunk);
reportHeadline.SpacingBefore = 12.0f;
pdfDoc.Add(reportHeadline);
