How to Find and Make Text Editable in a Protected DOCX Document in .NET Core?

Syncfusion® Essential® DocIO is a .NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can find and make text editable in a protected DOCX document using C#.

Steps to find and make text editable in a protected DOCX document:

1. Create a new .NET Core console application project.
   
   
2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org.
   
   

3. Include the following namespaces in the Program.cs file.
   C#

using Syncfusion.DocIO.DLS;
using Syncfusion.DocIO; 

4. Use the following code example to find and make text editable in a protected DOCX document
   C#

// Load the Word document
WordDocument document = new WordDocument(Path.GetFullPath(@"Data/Template.docx"));
// Find all instances of the target text (text, case-insensitive, whole word match)
TextSelection[] textSelections = document.FindAll("Adventure Works Cycles", false, true);
// Append editable ranges around each matched text.
foreach (var selection in textSelections)
{
    AppendEditableRange(selection);
}
// save and close the document
document.Save(Path.GetFullPath(Path.GetFullPath(@"../../../Output/Result.docx")));
document.Close();

5. Use the following helper method to insert editable ranges:
   C#

public static void AppendEditableRange(TextSelection selection)
{
    // Get the text range from the selection.
    WTextRange[] textRanges = selection.GetRanges();
    if (textRanges.Length > 0)
    {
        // Get the first and last text ranges in the selection.
        WTextRange startTextRange = textRanges[0];
        WTextRange endTextRange = textRanges[textRanges.Length - 1];
        // Get the paragraph that owns the start text range.
        WParagraph paragraph = startTextRange.OwnerParagraph;
        // Create a new EditableRangeStart and assign it to everyone by default.
        EditableRangeStart editableRangeStart = new EditableRangeStart(paragraph.Document);
        editableRangeStart.EditorGroup = EditorType.Everyone;
        // Find the index of the start text range within the paragraph's child entities.
        int startTextRangeIndex = paragraph.ChildEntities.IndexOf(startTextRange);
        // Insert the editable range start before the start text range.
        paragraph.ChildEntities.Insert(startTextRangeIndex, editableRangeStart);
        // Create a new EditableRangeEnd linked to the start.
        EditableRangeEnd editableRangeEnd = new EditableRangeEnd(paragraph.Document, editableRangeStart);
        // Find the index of the end text range and insert the editable range end after it.
        int endTextRangeIndex = paragraph.ChildEntities.IndexOf(endTextRange);
        paragraph.ChildEntities.Insert(endTextRangeIndex + 1, editableRangeEnd);
    }
}
