Hello,

This is entirely possible and depends on the size of the data set that you're processing.

My recommendation is to take a look at the virtualization demo. It moves the heavy work required for grouping and filtering to the server, greatly improving the performance.

A sample back-end service is distributed with the ASP.NET MVC wrappers for Kendo UI (wrappers\mvc\demos\Kendo.Mvc.Examples\Controllers\DataViz\Financial\VirtualizationController.cs).

Detailed documentation will be available soon.

Getting this problem in IE7 & IE8  only

Hi,

This is somewhat expected, as they're likely to be the slowest browsers that you're testing with.

Kind regards,
