ASP.NET with Telerik Controls Performance Tuning?

Question

I am using Telerik controls in an ASP.NET Website. It takes time while sending an Ajax request.

Is it advisable to use Telerik controls?

Do Telerik controls affect the performance of the ASP.NET website?

Please let me know tricks to identify the memory leak in an ASP.NET application, specifically in aspx.cs pages.

Answer 1

Every additional control on a page will affect the perfomance. Complex controls more so than simple controls.

With the telerik controls (which also consists of complex and powerful controls like grid, editor, treeview etc), it is quite easy to badly affect performance. One of the most common causes is probably excessive ViewState.

That said, most of the time you can optimize the performance. As a starting point, search the telerik site for performance optimization articles. You can find some of the commmon performance optimization articles on the support page for ASP.NET AJAX controls (in the section Performance). E.g:
