Views define their associated grid's fixed header and fixed footer sections, which are non-scrollable regions usually located at the top and bottom of a grid, and its header and footer sections, which are scrollable regions usually located, respectively, beneath the fixed header and above the fixed footer sections (see Example 1).
By default, a grid will have a HierarhicalGroupByControl and ColumnManagerRow in its fixed header section. In XAML, the content of a header, footer, fixed header, and footer sections can be cleared by setting the UseDefaultHeadersFooters property of a view to false (see Example 2). If left to true, any items that are added to a header or footer section will be added after the default headers and footers.
