We would like to display data from ESRI Shapefiles with up to 200,000 points and are wondering if this is possible with the asp.net ajax RadMap.
Right now, we're looking just at performance with a RadClientDataSource loading from a JSON file with 40,000 Points displayed as simple black circles. Panning is fairly fast, but zooming in or out one level takes about 4 seconds, even when none of the points are in view.
I've seen a lot of information on the Silverlight and WPF forums about getting decent performance with ~200,000 points as long as very few are in view at one time, which would be acceptable, but unfortunately we cannot use these platforms.
Does the UI for ASP.NET AJAX have anything like the dynamic layer that would improve performance when a lot of data is out of view? Or are there any other strategies to improve performance when this much data needs to be loaded?
Thanks in advance,
