Is there are built-in way to have a 'close all' option appear in the RadTabControl's drop-down menu? We have a close button on each tab, but it would be nice to also have an option in the drop down to close everything out.

Can this also be easily done in a context menu?

Hello Greg,

There is no such built-in functionality, actually the close buttons on the tabs are not built-in and are application specific logic, so you should do this on your own (i.e. modify the ControlTemplate of the RadTabControl and add your specific logic).

Can you provide an example of this?

I should also clarify that we've had little success in this. We use an ItemsSource for most all of our RadTabControl instances, and adding in a DropDownMenuItem to the ControlTemplate causes exceptions at runtime. I would rather not completely refactor code to manually add items to every single RadTabControl we use, so what is a better option?

I've thought about adding an item to our RadTabControl that's hidden somehow, making it's title "Close All Tabs", but this is a straight-up hack. I'd rather use something a bit more elegant.

Hello,

 To achieve this, I would suggest subclassing the RadTabControl and extending its logic. For example, you can create a DelegateCommand (or any other command) as a property of the customized tab control. Then you can edit the default control template and place a button and bind it to this custom close command. As the command is inside the tab control itself, you would have access to the container generator of the control, so that you can handle both Items and ItemsSource scenarios to get the containers and remove or hide them. This approach will also make the control reusable.

Please let us know if you need further assistance.
