Answer 1

telerik asp.net ajax controls provide a quite rich client-side api. it's their most attractive side for me.

Answer 2

I have experience with Telerik and DevExpress. As others have noted, DevExpress is probably the fastest; however, I still strongly prefer Telerik. Their big advantage is that they have been around a very long time and have a huge support database. Compared to every other .Net control library I've worked with, theirs is, by far, the easiest to get help for.

Considering that each library will have its own nuances and bugs, going with the one with the most vibrant user community and support forum is a smart move.

One more point, DevExpress's AspXPivotGrid is fantastic. Clients absolutely love pivot grids, and they are a smart move for the first report and clients will cut you a lot of slack when they can build their own reports.

Answer 3

How about "obout" controls.

This is suggested by some one .But i am facing performance issues now.Page load is very slow.I am not sure its the controls causing the problem.

Answer 4

The consensus here at SO seems to be DevExpress. Telerik and ComponentArt are good, too. DevExpress seems to be the fastest performer.
