Return Html with TrackChange and with Accepted Track Change

[Emin Sadigov]

Hello,

Is any way to return:

1. Html with Track Change marks and comments to store it in the database for next edit session?

2. Auto accepted html.

I tried in cs: RadEditor1.Content - but it return content without changes, RadEditor1.GetHtml(EditorStripHtmlOptions.AcceptTrackChanges) - but also track changes were not accepted.

Can you provide any example, please?

Thank you!

Hi Emin,

Straight to the questions:

1. You can obtain the specific Track Changes and Comments HTML formatting through the RadEditor1.Content property: 
   
   

           protected void Submit_Button_Click(object sender, EventArgs e)
           {
               TextArea1.Text = RadEditor1.Content;
           }

   
   
2. You can call the AcceptTrackChanges() method before the GetHtml one and the track changes will be accepted:
   
   

           protected void Submit_Button_Click(object sender, EventArgs e)
           {
               RadEditor1.AcceptTrackChanges();
               TextArea1.Text = RadEditor1.GetHtml(EditorStripHtmlOptions.AcceptTrackChanges);
           }

Thank you, Rumen. My fault was that I haven`t used Page.IsPostBack, so it is fixed by this code:

if (!Page.IsPostBack)
{
    RadEditor1.Content = "Initial text";
}

 

So, now I try to get Content with accepted TrackChanges and without Comments. This code seems correct, however empty Comments <span> remain when I use this parameter:

EditorStripHtmlOptions.Comments

in the code:

protected void Submit_Button_Click(object sender, EventArgs e)
{
      RadEditor1.AcceptTrackChanges();
      TextArea1.Text = RadEditor1.GetHtml(EditorStripHtmlOptions.AcceptTrackChanges | EditorStripHtmlOptions.Comments);
}

Seems UI Remove All Comments command is working better and remove <span> tag also.

Also UI Accept Track Change is working better and remove <strong> if word was removed, but code above remain empty <strong> tag. Or is it Filters? How can I use them in backend in the code above to clean from comments and accept track changes without empty tags?

If there are empty span tags left after programmatically accepting the track changes, you can perform a regexp-based stripping of the empty tags, e.g.

protected void Submit_Button_Click(object sender, EventArgs e)
{
    // Accept all track changes
    RadEditor1.AcceptTrackChanges();

    // Get HTML with accepted track changes and strip comments
    string acceptedHtml = RadEditor1.GetHtml(EditorStripHtmlOptions.AcceptTrackChanges | EditorStripHtmlOptions.Comments);

    // Clean up empty tags
    acceptedHtml = System.Text.RegularExpressions.Regex.Replace(acceptedHtml, @"<[^/>][^>]*></[^>]+>", string.Empty);
    TextArea1.Text = acceptedHtml;
    // Save to the database logic here
}

Hello, Rumen. Thank you, It is better. However the code after Comments is still bad. Look before:

<h2>Key <span class="reComment reU0" author="Alen Landar" comment="test" title="Alen Landar: test: 7/4/2024, 2:06:12 PM" timestamp="1720087572798">settings </span>and features</h2>

After code above converts into:

<h2>Key <span>settings </span>and features</h2>

 

So, it is possible to write regex to cleans spans without attributes. But if any other solution is available, which work like a UI Remove All Comments, it will be better.

I see, you can try this to strip the span tags without attributes like this:

 // Remove empty span tags and other empty tags
    acceptedHtml = System.Text.RegularExpressions.Regex.Replace(acceptedHtml, @"<span[^>]*>\s*</span>", string.Empty);

// Remove <span> tags without attributes
    acceptedHtml = System.Text.RegularExpressions.Regex.Replace(acceptedHtml, @"<span>\s*(.*?)\s*</span>", "$1");
