We have questions about free .NET libraries and applications, but I’m curious about what ASP.NET control packages you’ve used that provide the best bang for your buck. Yes, paid stuff.
I’ll get the ball rolling by saying I love the Telerik controls, but their price tag isn’t great. The one reason I would say the value is the greatest here because of the licensing, which makes deployment so easy.
I have both Telerik and DevExpress and I find myself, more and more, moving away from the Telerik stuff and using more of the DevExpress controls. I particularly like the DevExpress reporting package (the Telerik one was unusable) and the Grid / PivotGrid. However, Telerik does have better AJAX management helpers (although I no longer use them as I’ve learned enough about ‘raw’ AJAX) and the Telerik Editor control is the best there is.
So…one vote here for DevExpress.
