The company I work for uses an ASP.NET grid component from a commercial vendor, but won’t upgrade the buggy old version we have to a newer version because of cost. Are there open-source alternatives to these Uber-Grids that we could take advantage of?
I’m specifically looking for hierarchical drill-down capabilities. I know there are some Javascript library plugins (stuff for jquery UI, etc) that could be used, but I would prefer a server-side control given the current coding conventions at my employer (server-side controls whenever possible, javascript when nothing else will work 😛 )

Check out the DEMO page for the grouping feature, not sure how many levels you can go in though.
