Remarks

TabPanel is a Panel designed to handle the intricacies of laying out the tab buttons in a TabControl. Specifically, it handles: Serving as an ItemsHost for TabItems within a TabControl Determining correct sizing and positioning for TabItems Handling the logic associated with MultiRow scenarios, namely: Calculating row breaks in a collection of TabItems Laying out TabItems in multiple rows based on those breaks Performing specific layout for a selected item to indicate selection, namely: Bringing the selected tab to the front, or, in other words, making the selected tab appear to be in front of other tabs. Increasing the size pre-layout size of a selected item (note that this is not a transform, but rather an increase in the size allotted to the element in which to perform layout). Bringing the selected tab to the front Exposing attached properties that allow TabItems to be styled based on their placement within the TabPanel.
