Free ASP.Net controls for non-profits / charities

I am doing a website for a charity outside of work. I can't use the normal control libraries I wo开发者_如何学JAVAuld use at work because of the licencing (they won't let me), and predictably the charity can't afford them for a one-off project. I am particularly struggling for a good grid control and a hierarchy diagram control.

Do any of the vendors give free licences to these kind of projects? Or are there other good options?

Why is customising the built-in .NET ones out of the question? Does your client have some special requirements?
