I have written previously about my solution for providing sorting support to the DataGridView using a custom BindingList<T> and an implementation of my own ISortComparer<T> interface. In that solution, I had provided logic for trying to compare a few simple types generically using reflection. However, a coworker recently pointed out that trying to cast the property values to IComparable would allow for a more robust comparison that does not rely in switching the object’s type. I think this is a much more elegant solution and provides support for more data types as long as they support IComparable, which many basic framework types do.
I’ve updated the gists from previous post, but I wanted to go ahead and post about the new method. The updated GenericSortComparer contains the updates from this post.
