How to do it...

Follow these steps to add menus to your WPF application:

1. Open the MainWindow.xaml page, and replace the default Grid with a DockPanel. We will discuss more about this panel in the next chapter.
2. Now add the Menu control inside the DockPanel. This will create the base to hold all the menu items.
3. You can then add root-level menu items and sub-menu items in a hierarchical fashion, as shown in the following code snippet:

<DockPanel> 
    <Menu> 
        <MenuItem Header="File"> 
            <MenuItem Header="New" /> 
            <MenuItem Header="Open" /> 
            <MenuItem Header="Save" /> 
            <Separator /> 
            <MenuItem Header="Exit" /> 
        </MenuItem> 
        <MenuItem Header="Edit"> 
            <MenuItem Header="Undo" /> 
            <MenuItem Header="Redo" /> 
        </MenuItem>
