RadCombobox Filtering not working and shows error ""Stop running this script? A script on this page causing IE to run slowly..."

[Muhammed]

Hi,
We are using Telerik Rad Combobox in many pages of multiple applications. All pages were working fine till recently.

All of a sudden users are not able to filter data in Combobox by typing keywords. The filtering is not working properly and also results in the below error in almost all pages.

"Stop running this script? A Script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive. Yes / No" 

This happens in multiple applications hosted on multiple servers.
Any idea on how to troubleshoot this issue?

Our applications are running on .Net 2.0 and Telerik version is 2008.2.826.20

Thanks in advance,
Muhammed Saleem

Hello Muhammed,

We improved the performance of the filtering in IE a few Qs ago. Please consider upgrading to a newer version.

All the best,

Hi Simon,

Thanks for the reply.
Could you recommend the appropriate version that would be compatible with .Net 2.0 as well as offers improved performance while filtering in IE?

Thanks again.

Hello Muhammed,

The first version having filtering optimizations is Q1 2011 (version 2011.1.315). Unfortunately it does not have .NET 2.0 builds.
