When the popup is located on the bottom side of the document and it is also close to the end of the presenter and a user opens it, then the popup goes outside the area.

When trying to import a document containing bookmark and BookmarkRangeEnd is after the last paragraph, a StackOverflowException is thrown in IntervalNode while trying to rebuild the document cache. (RadDocumentChildrenCache.RebuildTree()).

The same could be observed if the bookmark end is last in the header/footer, between table cells in the RadDocument body, or when all paragraphs after the bookmark range end are hidden (with vanish property).

Workaround: Detect the problematic annotations and remove them:
foreach (var rangeStart in document.EnumerateChildrenOfType<AnnotationRangeStart>())
{
    if (rangeStart.End == null || rangeStart.End.Parent == null || rangeStart.End.Parent.Parent == null)
    {
        //MessageBox.Show("This indicates a problem.");
        rangeStart.Parent.Children.Remove(rangeStart);
    }
}

Note: Until 2017 R2 SP1 release StackOverflowException is thrown, after this release an ArgumentException should be thrown.

There is a NullReferenceException thrown while trying to compare positions for restoring them after pasting the document. The exception is handled but after it is thrown, the layout stops updating.

To reproduce: 

protected override void OnClosing(CancelEventArgs e)
{
    this.radRichTextBox.Document = null;
    base.OnClosing(e);
}

Use the attached project to reproduce. 

- Click the "Go To endPosition" button. The Caret remains on the same line.

The font family of the fields is changed to Times New Roman while importing RTF documents. The issue is a regression caused in 2019 R3 (LIB 2019.2.610)

StackOverflowException is sometimes thrown while a document containing annotations is updated in the main thread (e.g. by typing in it), and spell checking is enabled.

The exception is thrown in a background thread, which call stack similar to this one:

Quickly adding/removing of tab stop from the document's ruler crashes the application.

1. Open RadRichTextBox
2. Click to Home tab -> Paragraph group-> Multilevel list button
4. Click to "Define New List Style"
5. In "Apply formatting to" select 4th level. Don't select '1','2','3' beforehand, select '4' right after '1'st level.

Observed result: All text except the 4th level is bold.

Expected result: Only 4th level text is bold.

It should be located on a new line. Instead, it is located on the same line where the text is.

HtmlFormatProvider cannot import a document that contains an image with invalid URI format. An UriFormatException is thrown and the whole import fails. Similar errors should be handled and the document should be imported.

While importing definition of a font similar to font:400 15px 'arial'; where the font-weight is defined as a number, this number is parsed as value for font size instead of mapping it to font-weight.

HTML export of RadRichTextBox to perform font-size export in different units.

If you export a document using the HtmlFormatProvider, all style properties which contain measurement units are exported in pixel units. This makes the exported documents look much smaller when opened on devices with higher pixel density.

WORKAROUND: use Regex to find, convert and replace the font-size attributes

            HtmlFormatProvider html = new HtmlFormatProvider();
            string res = html.Export(document);
            Regex regex = new Regex(@"font-size: [0-9]*\.?[0-9]*px");
            Match match = null;

            do
            {
                match = regex.Match(res);
                if (!match.Success)
                {
                    break;
                }

                string value = match.Value.Substring("font-size: ".Length, match.Value.Length - "font-size: ".Length - "px".Length);
                double pts = double.Parse(value) * 72 / 96;
                res = res.Replace(match.Value, @"font-size: " + Math.Round(pts, 4) + "pt");
            } while (match.Success);

            File.WriteAllText("output.html", res);

Hi support,

We have a problem when we copy a text from MS word to RitchTextBox.
If the text copied uses an style that the namecontains tilde, then style name on the ritchtextbox is broken with strange characters.
All works well with this strange characters, but if you export to html and then import to ritchtextbox, the style is lost ...

This is a big problem because in spanish, many styles have tildes. When our user copy content from word they have problem with html format export / import.


I Attach a MS Word docx with a style with tildes:

Steps to reproduce it:

1- Open MS Word attached.
2- Copy the content.
3- Open a ritchTextBox Editor
4- Paste the content.
5- Export to html
6- Import the html.

You can see now, that the style are lost, and the name of the style contains strange characters.

Similar issue its happen when open a Word Docx with styles with tildes from ritchTextBox, not include strange characters but the style is lost.

 

Thanks for you support,

Bullet and numbered lists are still displayed as toggled in the ribbon even though the user has broken the lists. The toggle is removed only when the user clicks over the document.

When an HTML document contains a div and a span just after it, the span is imported as a child of the div. As a result, the span inherits some of the settings applied to the div.

In this example, the current synchronization context is "occupied" by the task that sets the RTF string forcing the arrange tasks to wait for it to complete before they can start. However, it can never complete as it is blocked by the wait call for the arrange tasks that will never run, causing a deadlock.
