    The InlineUiContainer is allowed to be inserted into RadRichTextBox officially by Telerik.

    But there're some problems:

    When I insert  a <Textbox> in to  RadRichTextBox 

                                <TextBox Width="100" Height="50"/>

           The TextBox can be shown in the RadRichTextBox correctly, and input charactors in inner TextBox correctly. But when I press "Backspace", the cursor will jump to to outer RadRichTextBox instead of delete the last character in inner TextBox !

           I used to think it's caused by the Microsoft WPF and Telerik WPF these 2 mechanisms (incompatible).Then I tried to use a RadTextBox, but no this control (with the acceptable reason: no color can be set on this control, so theme is unnecessary). 

           Fortunately, I found a Telerik control called telerik:RadMaskedTextInput, then I tried it as 

                                <telerik:RadMaskedTextInput Width="100" Height="50" TextMode="PlainText"/>

           But the problem is still !!!!  Press "backspace" in the inner RadMaskedTextInput will make the cursor jump into the outer RadRichTextBox .............

           On the other hand, if you insert a RadRichTextB​ox into a RadRichTextBox ,  the cursor is Okay both in inner and outer RadRichTextBox .

           I'm using ver 2014Q3.

           Then Whether this problem has been fixed now ? If yes , could you please tell me the ver?

    Hello Ruyu,

    RadRichTextBox gets the focus and executes its DeleteCommand when the Backspace is pressed. You could override this command with a custom one with the corresponding logic. I am attaching a sample project, which demonstrates how you could achieve the desired behavior. 

    Hope this helps.
