in order to achieve the desired changes, you need to override RadTabItem
's style. You must also change item's ControlTemplate
a bit in order to customize the hover and selected states of each item.
As you are using Implicit Styles
, after you have successfully applied the theme (in your case Office2016) and merged the required by RadTabControl
dictionaries, you must create a new style, based on the RadTabItemStyle
, and override its Template
property (needed for hover and selected states), as well as the properties that you mentioned, i.e. HorizontalContentAlignment
(responsible for each tab's text alignment), Padding
(responsible for the space around tab's text) and Background
Please, check the attached sample that demonstrates the described above approach, and let me know if it helps.
