            Content="open"
            DataContext="{Binding Commands, ElementName=richTextBoxAdv}" />

        <telerik:RadRichTextBox x:Name="radRichTextBox" Grid.Row="1" />


    </Grid>
</Window>

I get an exception on fireing the command.

 

"System.ArgumentException" in PresentationFramework.dll

Hi Dietmar,

Thank you for sharing the sample code.

To ensure that the commands of RadRichTextBox can be bound as expected to the different controls, you will need to ensure that the name of the RadRichTextBox instance is the same as the one passed as ElementName for the binding. In the sample code, both names are different and the binding is not working. Here is how I changed the code:

<telerik:RadRibbonButton
    x:Name="OpenDocumentButton"
    Margin="0,2,2,2"
    telerik:RadRichTextBoxRibbonUI.RichTextCommand="{Binding OpenDocumentCommand}"
    Content="open"
    DataContext="{Binding Commands, ElementName=radRichTextBox}" />

<telerik:RadRichTextBox x:Name="radRichTextBox" Grid.Row="1" />

Hope this is helpful.
