Hi,
 
I have used Kendo UI in an MVC web application. Of late I have been experiencing slowness in IE8 browser.
While the same code loads the screen in less than 2 secs in Chrome/IE10, it takes more than 5-6 seconds to load in IE8 browser.
Kendo widgets used in the screen includes Dropdowns, Treeview and Kendo Tabstrip.
I have tried replacing the kendo dropdowns with normal ones. This gave me a slight improvement of about 1 sec.
The kendo dropdown is a part of my cshtml page and not initialized by the jquery. Is this the best way to implement kendo widgets?
Is there any other way which will provide me with a better performance?

Hello Akhil,

Performance can be affected by the amount of HTML markup and scripts on the page. That includes the number of widgets and the number of their items, event handlers, etc.

A best practice is to load stuff on demand and avoid loading large quantities of data. With regard to Kendo UI, you can try the following techniques:

http://demos.telerik.com/aspnet-mvc/dropdownlist/serverfiltering

http://demos.telerik.com/aspnet-mvc/treeview/remote-data-binding

http://demos.telerik.com/aspnet-mvc/tabstrip/ajax

Generally, the performance of IE8 can never be as good as the one of new browsers, but judging by the provided information, the discussed page is heavy for all browsers and optimization may be desirable.
