Move to Previous Tab Group

[Satoshi]

Hi.

Using dll version 2021.2.615.40

I want to use the "Move to Previous Tab Group" included in the demo application, but it is not displayed in my application.

Are there any conditions under which this menu item is valid?

Hello, Satoshi, 

All context menu related operations are handled by a stand alone service, registered with RadDock - ContextMenuService. Additional information about the ContextMenuService is available in the following help article: https://docs.telerik.com/devtools/winforms/controls/dock/architecture-and-features/using-the-contextmenuservice 

Note that the context menu items depend on the DockWindow.DockState and whether the document can be moved backward and forward. Please refer to the attached gif file illustrating better how different menu options are displayed according to the user interaction.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

[Satoshi]

thank you for your answer.

I made a minimum code and confirmed it.

Apparently, it's useless if it contains a control that includes RadDock.

Is there a way to solve it without changing the controls that include RadDock?

According to the provided screenshot, I suppose that you have more than one RadDock controls on the form. Is my assumption correct? Please have in mind that RadDock is a container control and it is expected and highly recommend to have only one RadDock control on the form. Thus, all inner contains (a.k.a split panels) will belong to one common RadDock and when you move the document windows to different positions, the context menu options will be updated according to the available containers in this common RadDock. If multiple RadDocks are present, the split panels are considered separately per control and the menu options will be more restricted.

In case you are still experiencing any further difficulties, it would be greatly appreciated if you can submit a support ticket from your Telerik account and provide a sample project demonstrating the undesired behavior that you are facing. Thus, we would be able to make an adequate analysis of the precise case and provide further assistance. 

Should you have further questions please let me know.

You don't have to believe me

Is there a way to add my own menu that behaves the same as "Move to Previous Tab Group" or "Move to Next Tab Group"?

Finally, I replaced the inner RadDock with RadPageView and solved it.

Hello, Satoshi, 

Please have in mind that RadDock takes into consideration the exact window and where it is placed according to the neighboring split containers within the same RadDock control. Even though you may add a new custom context menu item, the "Move to Previous Tab Group" operation may not be allowed for this document at this particular moment. 

However, I am glad that RadPageView fits your custom scenario in a better way. Feel free to use it if it achieves the desired look and user experience.

If you need any further assistance please don't hesitate to contact me.
