How do I perform a culture-insensitive sort using the DataGrid?

Question

By default, System.Web.UI.WebControls.DataGrid will sort String-based columns using a culture-sensitive sort. This can cause unexpected results when sorting product numbers that contain hyphens. For example, items will be sorted as 10-199, 103-10, 10-399 rather than 10-199, 10-399, 103-10.

How can I have the DataGrid sort a column of Strings using a culture-insensitive sort?

Answer 1

The only solution I have found is to create a new class inheriting from DataGrid and override the OnSortCommand method with your own custom sort.
