How to preserve simple markup, all markup, and no markup of track changes during Word to PDF conversion

Syncfusion .NET Word Library (DocIO) used to create, read, edit and convert Word documents programmatically without Microsoft Word or Interop dependencies. Using this library, you can** preserve simple markup, all markup, and no markup of track changes during Word to PDF conversion in C#**.

Steps to preserve simple markup, all markup, and no markup of track changes in Word to PDF :

1. Create a new ASP.NET Core Web application (Model-View-Controller) project.
   
   
2. Install the Syncfusion.DocIORenderer.Net.Core NuGet package as a reference to your project from NuGet.org.
   
   

3. Include the following namespaces in the HomeController.cs file.

C#:

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;
using Syncfusion.DocIORenderer;
using Syncfusion.Pdf;

4. A default action method named Index will be present in HomeController.cs. Right click on Index method and select Go To View where you will be directed to its associated view page Index.cshtml.
5. Add a new button and drop down options in the Index.cshtml as shown below.

C#:

@{
   Html.BeginForm("ConvertWordtoPDF", "Home", FormMethod.Get);
   {
       <div class="Common">
           <div class="tablediv">
               <div class="rowdiv">

               </div>
                
               <div class="rowdiv" style="border-width: 0.5px;border-style:solid; border-color: lightgray; padding: 1px 5px 7px 5px">
                   <div class="rowdiv" style="margin-top: 8px">
                       <input type="submit" value="Convert Word to PDF" name="button" style="width:200px;height:27px" />
                       <br />
                   </div>
                   <div>
                       Select Track changes option:
                       <select id="TrackChangesOptions" name="TrackChangesOptions">
                           <option value="0">Simple Markup</option>
                           <option value="1">All Markup</option>
                           <option value="2">No Markup</option>
                       </select>

                   </div>
               </div>
           </div>
           <br />
       </div>
   }
   Html.EndForm();
}

6. Add a new action method ConvertWordtoPDF in HomeController.cs and include the below code snippet to preserve simple markup, all markup, and no markup of track changes during Word to PDF conversion.

C#:

//Open the file as Stream.
using (FileStream docStream = new FileStream(Path.GetFullPath("Data/Template.docx"), FileMode.Open, FileAccess.Read))
{
   //Loads file stream into Word document.
   using (WordDocument wordDocument = new WordDocument(docStream, FormatType.Automatic))
   {
       #region Track changes option
       //Sets revision types to preserve simple markup track changes in Word to PDF conversion.
       if (TrackChangesOptions == "0")
       {
           wordDocument.RevisionOptions.ShowMarkup = RevisionType.Deletions | RevisionType.Formatting | RevisionType.Insertions | RevisionType.MoveFrom | RevisionType.MoveTo | RevisionType.StyleDefinitionChange;
           wordDocument.RevisionOptions.ShowInBalloons = RevisionType.None;
       }
       //Sets revision types to preserve all markup track changes in Word to PDF conversion.
       else if (TrackChangesOptions == "1")
       {
           wordDocument.RevisionOptions.ShowMarkup = RevisionType.Deletions | RevisionType.Formatting | RevisionType.Insertions | RevisionType.MoveFrom | RevisionType.MoveTo | RevisionType.StyleDefinitionChange;
       }
       //Sets none revision type to preserve no markup track changes in Word to PDF conversion.
       else if (TrackChangesOptions == "2")
       {
           wordDocument.RevisionOptions.ShowMarkup = RevisionType.None;
       }
       #endregion
       //Instantiation of DocIORenderer for Word to PDF conversion.
       using (DocIORenderer render = new DocIORenderer())
       {
           //Converts Word document into PDF document.
           PdfDocument pdfDocument = render.ConvertToPDF(wordDocument);

           //Saves the PDF document to MemoryStream.
           MemoryStream stream = new MemoryStream();
           pdfDocument.Save(stream);
           stream.Position = 0;

           //Download PDF document in the browser.
           return File(stream, "application/pdf", "Sample.pdf");
       }
   }
}
