Grid for .NET WinForms?

Question

.NET

I have been looking for a good grid for .NET WinForms for a long time.
All existing grids have certain drawbacks - you can’t load more than 20-30 thousand lines into some, into some non-customizable filters (or they don’t exist at all).
Required functionality:
- display and display before the eyes of the user 10-20 million (or more) rows (naturally, in virtual mode)
- while allowing the user to filter data in columns
- so that the filter is customizable (well, or has as many initial options, in particular - filtering by regular expression is required).
Something like that.
Thank you.

Are you considering paid? Have you tried DevExpress Grid?

Answer 2

Obviously, there is a logical error here. If you display something to the user, then it is assumed that he will actually interact with it. Can your user actually view at least 1 million of your 20 million posts?
Reconsider the logic of your application, displaying even "20-30 thousand lines" is already a very strange use case, not like your example.

I highly recommend iGrid, it also has an autofilter plugin, just like in Excel. I ran it on tables with 100,000 rows, 20 columns of various types, I didn’t notice any brakes - I think it will easily handle a larger amount of data.
