RichTextBox Context Menu

[Cuthahotha]

Is it possible to add an item to a rich text box context menu?  I would like to test to see that a word is selected, then add to the context menu a "Add Keyword" menu item.

Thanks,
Steve

Hi Cuthahotha,
Take a look at our blog post about customizing RadRichTextBox's context menu and selection mini toolbar.

All the best,

I was using that Showing event handler, and noticed that a richtextbox declared in one page can access the same context menu as another richtextbox in another page?

Hello Edward,
The behavior you are observing is caused by the fact that MEF caches ContextMenu instances and reuse them for satisfying the imports of all RadRichTextBoxes - actually all RadRichTextBox instances uses the same context menu. You have two options:

• manually set different instances of ContextMenu to all your RadRichTextBox-es

  this.radRichTextBox.ContextMenu = new Telerik.Windows.Controls.RichTextBoxUI.ContextMenu();

• Create custom context menu that will be non-sharable. MEF will automatically load different instances of it for all RadRichTextBoxes on demand:

  [PartCreationPolicy(CreationPolicy.NonShared)]
  [CustomContextMenu]
  public class NonSharedContextMenu : ContextMenu
  {
  }

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

Kind regards,
