Open Source Alternative to ASP.NET Commercial Uber-Grids

Question

The company I work with uses the ASP.NET grid component from a commercial vendor, but will not update the old version with the error that we are using for the newer version due to cost. Are there any open source alternatives for these Uber-Grids that we could use?

I am specifically looking for hierarchical drilling capabilities. I know that there are some Javascript library plugins (material for jQuery UI, etc.) that can be used, but I would prefer a server control given my employer's current coding conventions (server controls whenever possible , javascript when nothing else works: -P)

Check out the DEMO page for a grouping function, not sure how many levels you can use, though.
