[WPF] Automatically sort a GridView (continued)

A few months ago, I wrote a post where I explained how to automatically sort a GridView when a column header is clicked. I had mentioned a possible improvement : add a sort glyph in the column header to show which column is sorted. In today's post, I present a new version of the GridViewSort class, which displays the sort glyph. To achieve this result, I used an Adorner : this is a component which allows to draw over existing UI elements, on an independant rendering layer.

[WPF] Automatically sort a GridView when a column header is clicked

It's quite simple, in WPF, to present data in a grid, thanks to the GridView class. If you want to sort it, however, it gets a little harder… With the DataGridView in Windows Forms, it was “automagic” : when the user clicked a column header, the grid was automatically sorted. To achieve the same behavior in WPF, you need to get your hands dirty… The method recommended by Microsoft is described in this article ; it is based on the Click event of the GridViewColumnHeader class.
