I have tried to use the RichTextBox, but found that it does not work very well when it comes to measure the text. This results in clipped text and that the caret can be displayed in a different place then expected.
This can easily be seen with a font like Gabriola, which uses complex kerning metrics. Type a text with a lot of "ff" and "fi" and you will soon see that your caret gets out of sync and that text is sometimes clipped.
When I look at the code of RichTextBox it seems to me that it uses its own calculation of text widths and that the this is based on a very simple method using just the kerning information. There is also a hard coded list containing information which fonts that has kerning info and which fonts that are mono spaced. It seems strange to me to have this in a config file since there is a large number of fonts used by the users.
It also seem to look at the Unicode character family in order to determine if ligatures are used or not, which is also quite strange since ligatures can be used for western characters too. The font Gabriola is an example of this. Look at "fi" in a word like "fine".
It can potentially consume a lot of memory since I think that it builds a dictionary of the kerning of all pairs of characters for all fonts that it encounters.
I guess this way of doing things were made for performance, but unfortunately, good performance doesn't help much if it doesn't work.
I am not sure if I should report this as a bug, since it is more of a fatal design issue of the whole control.

For now, We can drag or paste Images into RadRichTextBox. But still can't drag or paste files like RichTextBox in Winform. It's very inconvenient!

We need to support uneditable areas in the document flow. The closes analog in HTML is <div editableContent=false>...</div>.

MS-Word allows a user to toggle the markup and edit the document as final when track changes are enabled. This feature request is allowing something similar in RadRichTextBox.

The issue is reproduced with Marathi IME. Type some letters, press and release shift, then press space. The result is that the current IME text is duplicated.

I am constructing a RadDocument in code. The document is protected, but contains several permission ranges where editing is allowed. The sections where editing is allowed contain some custom readonly ranges to further restrict editing. When I assign the RadDocument to the Document property on a RadRichTextBox, I get the exception and stack trace below in the RadDocument.IsInNonEditableRange function. I am using UI for WPF version 2014.1.331.40. The exception and stack trace are:
System.InvalidOperationException: Sequence contains more than one element

In Word I can place text where ever I want, when I use textfields. This should also be possible with RadRichTextBox.

When exporting to PDF this should result in an extra layer for the textfield.
