Add new PushButton when I click pushbutton

[qoreodlf37]

Hi, I have a question.

I created tab, pannel and some buttons.

Is it possible to create new pushbutton (Button3, Button4...) when I click  my "Create" button?

Yes, almost certainly. You just need access to the RibbonPanel object, create new PushButtonData objects, and call AddPushButton. Why would you want to do this? Is your goal to confuse your end user? Another possible approach would be to create all required buttons up front and only enable them when they are needed.

Hi @qoreodlf37 

    There is no direct method to achieve that functionality, But we have a workaround to achieve that.

1. Create all Button in the IExtetnal Application
2. Add "AdWindows" Dll and Hide Button2 and Button3
3. In Create Command UnHide the Button2 and Button3
