Question

What is the exact difference between ToolBarPanel and ToolBarTray in WPF?

Solution

Here you are

The ToolBar uses a ToolBarPanel and a ToolBarOverflowPanel in its ControlTemplate. The ToolBarPanel is responsible for the layout of the items on the toolbar. The ToolBarOverflowPanel is responsible for the layout of the items that do not fit on the ToolBar. For an example of a ControlTemplate for a ToolBar, see

https://docs.microsoft.com/en-us/dotnet/desktop/wpf/controls/toolbar-overview?view=netframeworkdesktop-4.8

Did you read the MSDN documentation? msdn.microsoft.com/en-us/library/ms752063.aspx. Essentially, you can put a ToolBar into a ToolBarTray, whereas a ToolBarPanel is used as a part of the ToolBar control template.

@elgonzo that link is now broken. Is there another?

@Thomas, the document is still there. When visiting the page, notice the "Other versions" link (it is a drop-down box) underneath the heading "This topic is no longer available". Choose one of the older framework versions to see the document (apparently, MS' documentation system screwed up and failed to import this page for the documentation of "newer" .NET versions). Or just follow this link... :)
