We're starting a new project and are considering using ExtJS. Our developers have come up with a list of questions that we're hoping to answer before making a decision.
1) Can/Should we embed ASP.NET controls within ExtJS layouts?
2) Will ExtJS controls be sufficient for all our needs? (This is of course impossible for anyone to answer, but general comments on the limitations of ExtJS may be helpful)
3) Can ExtJS be used effectively within Visual Studio?
4) In ExtJS model, application will be contained in a small set of large files, heavily JS coded
