WPF Interview Questions ,How can I get items in a StatusBar to grow proportionally?

It’s common to want StatusBar panes that remain proportionately sized. For example,

perhaps you want a left pane that occupies 25% of the StatusBar’s width and a right pane

that occupies 75% of the width. This can be done by overriding StatusBar’s ItemsPanel with

a Grid and configuring the Grid’s columns appropriately.
