c# - How to keep style on open xml documents -

I open XML (Microsoft Word - .Docx) as a file template to automatically generate other documents I am using. I have defined the content controls in the template document, and I have written the code to change the contents in the control of these materials. I

The content has been changed and the documents have been prepared, but I I am struggling to keep. In the Word, while inspecting the properties of content control, I have checked the checkbox for the "Use a style to format text in blank control" style, and "Remove content control when content is removed" Also checked for Documents do not have any effect when generated by code.

This is my code (Which was enough to help with a community member here) What should I do to keep the formatting for replacing the data in content control? Formatting is a simple text formatting, such as size and font Please suggest:

  change the private static zero copy (main documentpart main part, string tag name, string tag well) {// all tag field square tags Filters = Main Part Document. Body. Descendants & lt; SdBlock & gt; (). Where (r = & gt; rsdtproperties.getfarst chald & lt; tag & gt; () .val == tagname); Foreach (var field in tagFields) {// remove all paragraphs from the content block area. SDtContentBlock.RemoveAllChildren & lt; DocumentFormat.OpenXml.Wordprocessing.Paragraph & gt; (); // A new paragraph in which one run and one text element var new paragraph = new document format OpenXil Word Processing Make paragraph () Var newRun = New DocumentFormat.OpenXml.Wordprocessing.Run (); Var newText = new DocumentFormat.OpenXml.Wordprocessing.Text (tagValue); NewRun.Append (newText); NewParagraph.Append (newRun); // Add new paragraph in the content block field. SDtContentBlock.Append (newParagraph); }}  

When you specify a style to the content, a new RunProperties are added under the element SdTProperties . For example, if I allocate a new style named Style1 , then I can see that the following XML is ready:

  & lt; W: sdt & gt; & Lt; W: sdtPr & gt; & Lt; W: RPR & gt; & Lt; W: rStyle w: val = "style1" /> & Lt; / W: RPR & gt; & Lt; W: nickname w: val = "lastname" /> & Lt; W: tag w: val = "lastname" /> You need to capture this value and assign it to the new  paragraph  You can remove the same level as  SdtBlock  and then remove  SdtBlock , which does the same when you select the option to "Delete content off delete content option".  RunProperties  are  & lt; W: rPr & gt;  element The following should be done by you. 
 
  Private Static void ReplaceTags (MainDocumentPart mainPart, string tag name, string tag value) {// All tag fields are IEnumerable & lt; SdTBlock & gt; Tagfild = Menpart Document Body. Descendants & lt; STBLock & gt; (). Where (R = & gt; RSDTProperties.Getfest Chald & lt; tag & gt; () .val == tagname); Ingrad (different fields in the tagged field) {// SDTBlockOk RunPropertiesRunProp = Fields let's grab run properties. SdTProperties.GetFirstChild & lt; RunProperties & gt; (); // Create a new paragraph that contains one run and one text element paragraph paragraph = new paragraph (); Run New = New Run (); If (runProp! = Null) {// Assign RunProperties to our new run newRun.Append (runProp.CloneNode (true)); } Text new text = new text (tag value); NewRun.Append (newText); NewParagraph.Append (newRun); // Insert new paragraphs before the field that we are about to remove the field. Parents. Application (previously, new paragraph, field); Remove // ​​remove SdTBlock to copy the content control when the content is edited Option Field Remove (); }}
