Is it possible to bind a radrichtextbox command to it's context menu?

[Michael]

I've been working on a text editor for a website using the radrichtextbox.  I have the radrichtextboxribbonui in place and working spectacularly, as well as a radMenu, that is working well.  I bound the cut, copy, and paste buttons in the radmenu to those of the radrichtextbox with the xaml code:

<telerikNavigation:RadMenuItem x:Name="_cutMenu" DataContext="{Binding ElementName=_rrtbMessage}" Command="{Binding CutCommand}" Header="Cut" />
<telerikNavigation:RadMenuItem x:Name="_copyMenu" DataContext="{Binding ElementName=_rrtbMessage}" Command="{Binding CopyCommand}" Header="Copy" />
<telerikNavigation:RadMenuItem x:Name="_pasteMenu" DataContext="{Binding ElementName=_rrtbMessage}" Command="{Binding PasteCommand}" Header="Paste" />

And that works well.  I tried to do the same thing with a context menu, and non of the buttons seem to work.  They simply respond as if they had no command.  The code I've written for that is:

                   
<telerikDocuments:RadRichTextBox x:Name="_rrtbMessage" HorizontalAlignment="Stretch" Margin="10,35,10,10" VerticalAlignment="Stretch">
<telerikDocuments:RadRichTextBox.Resources>

         <dHTML:HtmlDataProvider x:Key="HtmlDataProvider" RichTextBox="{ Binding ElementName=_rrtbMessage}" Html="{Binding MessageText, Mode=TwoWay}" SetupDocument="SetupMessage" />
</telerikDocuments:RadRichTextBox.Resources>

<telerikNavigation:RadContextMenu.ContextMenu>

<telerikNavigation:RadContextMenu x:Name="_menuRtbFormat">

                        <telerikNavigation:RadMenuItem x:Name="_cutContextMenu" DataContext="{Binding ElementName=_rrtfMessage}" Command="{Binding CutCommand}" Header="Cut" />

                        <telerikNavigation:RadMenuItem x:Name="_copyContextMenu" DataContext="{Binding ElementName=_rrtfMessage}" Command="{Binding CopyCommand}" Header="Copy" />

                        <telerikNavigation:RadMenuItem x:Name="_pasteContextMenu" DataContext="{Binding ElementName=_rrtbMessage}" Command="{Binding PasteCommand}" Header="Paste"
</telerikNavigation:RadContextMenu>

</telerikNavigation:RadContextMenu.ContextMenu>

</telerikDocuments:RadRichTextBox>

Is there something I need to do differently because the context menu is nested inside of the RadRichTextbox I am trying to bind to?

Hello Michael,

I am attaching a project that shows two ways you can use to make the context menu work - in XAML and in code-behind.
Basically, what you need to change in your code is not bind the DataContext property of the RadMenuItem, but the DataContext property of RadRichTextBox as follows:

<telerikDocuments:RadRichTextBox x:Name="_rrtbMessage" HorizontalAlignment="Stretch"  Margin="10,35,10,10" DataContext="{Binding ElementName=_rrtbMessage, Path=Commands}">

If you have any other questions, do not hesitate to contact us again.

All the best,
Iva

Perfect, worked like a charm.
