The normal hyphen should break the line and the non-breaking hyphen (inserted with: alt+0173) should not break the line

An useful option would be to export the text without the bullets in it.

As a result RadDocument instances cannot be collected by the GC.

When the caret is positioned at the beginning of a paragraph with hanging indent and the user press Backspace, the left indent is set to a negative value, the text goes out of the bounds of the document. 

Workaround:
Use the editor's method instead of the command:

private void RadRichTextBox_CommandExecuting(object sender, CommandExecutingEventArgs e)
{
    bool? parameter = e.CommandParameter as bool?;
    if (parameter != null && parameter == true)
    {
        DeleteCommand command = e.Command as DeleteCommand;
        if (command != null)
        {
            e.Cancel = true;
            this.radRichTextBox.Delete(true);
        }
    }
}

Introduce an option enabling only proportional resizing to be allowed in the ImageSelectionAdorner (side middle thumbs should be disabled). The option can be added in the RadRichTextBox's ImageSelectionAdornerSettings as it already contains CanRotate, CanDrag, CanResize.

Note that Images could also support Lock aspect ratio property, which is different.

Loading/editing document with large lists (with 1561 or more items) throws IndexOutOfRangeException when incorrectly tries to convert numbering to letters.

Workaround: Change list type to one which does not include letter NumberingFormat in any of its levels, for example Numbered Hierarchical or custom one.

When trying to export a document which contains hyperlink pasted from Outlook, KeyNotFoundException is thrown. The color of the span is not registered.

To work around this, register a style with the same color:

StyleDefinition style = new StyleDefinition("test", StyleType.Character);
style.SpanProperties.ForeColor = Color.FromArgb(100, 200, 25, 104);
this.radRichTextBox.Document.StyleRepository.Add(style);

Bullet with a big font-size applied is not horizontally aligned with the rest of the bullets of the same level.

Steps to reproduce:
1. Add several paragraphs.
2. Apply a list to the paragraphs.
3. Select a paragraph in the middle.
5. Apply a big font-size, like 24.
6. Export to HTML.

Actual: The bullet with the bigger font-size is not horizontally aligned with the rest of the paragraphs.
Expected: All paragraphs should be horizontally aligned

 ArgumentException is thrown when a missing image with no width and height is imported from HTML format.

Steps to reproduce:
1. Import the attached HTML.
2. Wait for a few second for loading the image.

Actual: An ArgumentException is thrown for setting the width or height of an image to an infinity.

Fix available in LIB Version 2017.2.522.

When typing in RadRichTextBox, the characters appear in the document with slight delay.

When classes inheriting RadDocument are exported using XamlFormatProvider, XmlException with message "The prefix 't' cannot be redefined from 'clr-namespace:Telerik.Windows.Documents.Model;assembly=WpfApplication1' to 'clr-namespace:Telerik.Windows.Documents.Model;assembly=Telerik.Windows.Documents' within the same start element tag." is thrown

Similar scenario works with inheriting other elements.

Steps to reproduce:
1. Create an object which inherits the RadDocument
2. Pass the created object as a parameter for the XamlFormatProvider.Export() method
Observe: An XmlException is thrown
Expected: The object to be exported

Some customers are complaining that when the mini toolbar is shown, it is semi-transparent - they expect to be fully shown. Currently, this behavior cannot be customized. Think of adding some setting about how this toolbar will be visualized.

When the main container of a window is ScrollViewer, the caret is not kept in the view while users move it with the arrow keys.

Applying negative LeftIndent or FirstLineIndent of a paragraph in web layout mode will visualize the paragraph to the left of RadRichTextBox boundaries.

When an application is built with .net version 4.7, the paragraph dialog is clipped in the bottom.

The PreferredWidth property has a strange behavior when set to all columns of a table and one of the rows is with ColumnSpan greater than 1. The width is properly set, but seems to be not respected while measuring the table and its children.


Second Scenario using RichTextBox UI: Create a document containing a table with horizontally merged cells and custom set columns` width and export it to HTML. When importing this HTML document back to the RichTextBox the column width value was not preserved.

When a table cell contains nested table, and the paragraph after the nested table is empty, this paragraph could be collapsed, as in MS Word. This gives better look to nested tables, similar to how browsers visualize nested HTML tables.

Note that the paragraph should be visualized when the caret moves the position inside the paragraph.

Currently the paragraph is visualized with its full height, making the layout different than MS Word - it appears that there are redundant space after the nested table.

There is no document position at the end of a line when a single span is flowing to the next line. Therefore, in similar scenarios, the user cannot move the caret at the last position of the line.

Hyperlink tooltip is not changed when the HyperlinkNavigationMode property of RadRichTextBox is changed.

Workaround: Invoke radRichTextBox.ActiveEditorPresenter.RecreateUI() method just after the property value change:
this.radRichTextBox.HyperlinkNavigationMode = HyperlinkNavigationMode.Click;
this.radRichTextBox.ActiveEditorPresenter.RecreateUI();

Steps to reproduce:
1. Insert a hyperlink in RTB.
2. On button click change the HyperlinkNavigationMode.

Observe: The tooltip is not changed from Click to ... Ctrl + Click to .. and vise versa.
