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