Run the Word-inspired project. Select the one whole paragraph, right below the Overview header, but so that caret is at the beginning of the next paragraph. Change text alignment to Justify. Then try to change text alignment to Left. It will not turn back to Left. Probable reason is that caret is at beginning of the next paragraph whose alignment is Left, so app thinks it should change it to Justify instead. This over-eagerness is described in forum thread ChangeParagraphTextAlignment is over-eager to change alignment. But in this case there is no workaround.

The solution is to set the value instead of toggle it, like the Word does. If text alignment was Left then setting to Left should again set it to Left. Also, caret position should not change the outcome of the action. Only the contents of the selection is relevant in deciding if action can be safely skipped.

Case 1

   The editing capabilities of tables should be disabled when in ReadOnlyRange

Case 2,

    The Table tools are not hidden when changing the default tab ( see attached video).

The customers need to convert the position to an integer number representing the offset of the current position from the first position in the document. A method returning the position at a specified offset would be useful as well.

Some voice recognition software (Nuance) is using integer positions as well.

In MS Word, MS RichTextBox and DevExpress RichTextBox, the positions are represented as integer numbers.

To reproduce:
 - Add a table where the width is set to 100%
 - Import the table and the export it:
private void radButton_Click(object sender, RoutedEventArgs e)
    var provider = new HtmlFormatProvider();
    string text = File.ReadAllText(@"..\..\default.html");
    rtb1.Document = provider.Import(text);

private void radButton1_Click(object sender, RoutedEventArgs e)
    var provider = new HtmlFormatProvider();
    provider.ExportSettings.StylesExportMode = StylesExportMode.Inline;
    string content = provider.Export(rtb1.Document);
    File.WriteAllText(@"D:\test1.html", content);

 Leave the export mode intact.

When GoToBookmark method is called and the current position is before the bookmark, the screen is not repositioned, causing the bookmark sometimes to appear at the last visible row.

Hi Team,


We recently bought your Tool for one our Windows Forms Project work in VS2019 (4.7.2 framework). 

There is a need for us to have Emojis inside the editable Textbox / RichTextEditor in Color.

For example, if we paste Emojis inside the text editor, it should retain the color of the Emoji as it is. 

Currently if we paste the Emoji inside the text editor, its only pasting the Emoji but losing it's color. 

How to retain the color of the Emoji inside the editable Textbox / RichTextEditor ? Is there any property or so we need to set?

The users of our application can paste any kind of Emoji (like inbuilt Windows10 Operating System Emojis etc.,) and there is no limitation for this. 

Kindly advice.


with regards,

Krish TS,

Senior Technical Programmer Analyst,

In Word, for paragraphs in a list:

1. The bullet/number uses the value of the first line indent

2.1 The text on the first line is aligned according to the left indent when the left indent is smaller than the first line indent (the usual case).

2.2 If the first line indent is smaller than the left indent, the first line aligns with the rest of the text, using the value of the left indent property.

2.3 When there are tab stops, they are used for the position of the text. In RadRichTextBox, the text in the first line always aligns according to the FirstLine indent.

Also, tab stops can be used to position the text after the bullet/number.

Add Paragraph property controlling  whether SpacingBefore / SpacingAfter is applied between paragraphs with the same style.

In MS Word, the corresponding option is controlled with "Don't add space between paragraphs of the same style" checkbox in the font properties dialog - and the paragraph spacing after will not be applied. 

In OOXML, it is described with the w:contextualSpacing element. We don't respect this property on import of such files, and the paragraph spacing is bigger.

Common use case for this feature is that when list is applied to multiple paragraphs, Paragraph List style is applied to the items, and this style has "Don't add space between paragraphs of the same style" applied, so the vertical spacing between the items is smaller.

When deleting all content (e.g. Select All [CTRL+A] + Delete [Del]) in the document, it would be convenient for the user to preserve all formatting (local span formatting + local paragraph formatting + style) applied on the last paragraph. 

This will ensure that the user will continue edit the document with last current font, font family, etc.

If this operation is applied on an empty document, though, the styling of the single paragraph should be reset to the defaults for the document.

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.");

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

The dialog should match the strings contained in the different document parts (headers, footers, footnotes, endnotes, comments).

Please refer to the attached gif file.

Let's take for instance demo application with its default document, with text "RadRichTextEditor for WinForms" at the beginning in font Calibri of size 28. Suppose the user wants to add A, then empty line, then C in single line, followed by the rest of the document, and to have these three new lines in Times New Roman in size 10.

If there is no empty line, but letter B in middle line, then user can set caret to document start, set the font and size, and type A<Return>B<Return>C<Return>. And it would look fine (and even then, if we set caret just after B and press Return the new paragraph will have spacing after set to 7.5 for no apparent reason).

If we want an empty line instead of B in the line, then there is no simple way to do it. Typing A<Return><Return>C<Return> would produce a huge gap between A and C (we still first set the caret, and font and size). One way to accomplish what we want is to select all new text, set font size to something other than 10, and then back to 10 (which is also weird to have to do).
