title: What technologies are available for client side interactive data grid like UIs?
body: <p>I am currently working on a project for which we have developed very interactive data grid control using HTML, CSS and JavaScript(custom as well as JQuery). This all seems to be fine on high end client machines but our customer is complaining that the browsers are taking very long time to render the received data. </p>
  
  <p>We have noticed that typically a page is getting loaded and rendered in 1-2 seconds in almost all main stream browers running on win2k3 server with 3 Gig RAM and one 3 GHz processor but our customer has calculations going upto 25 seconds.</p>
  
  <p>My questions is basically that what are the options available if we want to use some other technology to speed up the rendering of pages with such interactive data grids where user can dynamically select the available columns in the data table and can pass client side events(javascript calls) to other flash contents on the same page. Thanks in advance.</p>
