Set the Content property display a text or any object inside a button.

Glyph
Use the BackstageItemWithImage.Glyph property to display a ButtonItem‘s icon.
Commands
The purpose of any button item is to perform certain actions when a button is clicked by a user. To bind an action to your button, use the BackstageButtonItem.Command property or the BackstageItemBase.Click event. See the example below to learn more.
Example
Imagine you want to create a BackstageViewControl with a button, a tab item and a separator item between them, as seen in the following figure:
To add these items via a XAML markup, define new BackstageButtonItem
, BackstageTabItem and BackstageSeparatorItem class objects between the opening and closing tags of a BackstageViewControl. When an end-user selects the tab item, a label and two radio buttons should be displayed at the right of BackstageViewControl. To add multiple items as a tab item’s content, define a container, place these items inside of it and initialize the ControlPane property with this container. In this example, a Grid container is used. The button item’s BackstageItemBase.Click event is used to respond to an end-user clicking this button.
