Hello,

I can't seem to figure out how the MSWordExample in the richtextbox demo works. I want to understand how when a user types something in the document, then selects and makes bold, it becomes bold. It seems that all you do is specify a command in the xaml to which the B is bound to: ToggleBoldCommand, however where is that command defined? I did something very similar, but it does not seem to work.

Thanks,
Olga

Hi Olga,

The "magic" happens in the RadRichTextBoxRibbonUI.RichTextCommand attached property. You can read more about it in this blogpost (a little outdated, but the main idea remains), this help page, and this forum thread (describing how to create your custom UI for the commands RadRichTextBox exposes).
Essentially most of the commands exposes event that is raised whenever state changes (e.g. the selection is over bold text); you can subscribe to this event and update the state of the control in the event handler.

Don't hesitate to contact us if you have other questions.
