Had a look at the ASPxDataGrid from DevExpress and noticed that it used XHR by default to load data which made it REALLY fast. It almost felt like running a real client side application written in jQuery/Angular/KendoUI or something like that. And this was with no custom coding required or anything like that, just drop it on the page and do databind via an ObjectDataSource and there you had it. Does Teleriks RadGrid support XHR or something similar so that the grid only has to be loaded once and can then just fetch data? If so, how do we use it (and not having to implement it manually that is)?
