We are using Telerik Rad Window in our application.
rad window object is not destroyed on close event of Rad window.so we are facing issue of memory leak.

we are using Telerik 2008 version.

we had used destroyonClose property but we are not able to solved the memory leak issue.its showing same memory usage after close window and its increase on opening a rad window.

Kindly provide us solution for the same.

Hello Chanda,

What is the tool you are using to confirm this? I am asking this because the Sieve tool for example is known to show false positives and the task manager is not a reliable tool for monitoring memory usage of a page, because its statistics depend on many system factors that usually are not even be related to the browser.

I strongly advise that you upgrade to the latest version which currently is Q1 2011 SP1. The version you are referring to is 4 years old and does not support modern browsers. In additional to support for new browsers you will also benefit from many fixes and improvements in the controls. I cannot confirm if the issue you report is an actual bug in your version or the problem stems from something in the exact project, but I can confirm that the DestroyOnClose functionality works properly in the latest versions.


Kind regards,

Hi Marin ,

Thanks for your reply.

We are using Process Explorer v15.05 tool to identify memory usage. Our application is on .Net Framework 4.0  And we have tried with IE6/7/8 browser but received same result.
Your reply says that "DestroyOnClose" is working fine in latest version; does it means there is some issue with this property in telerik version 2008 Q2 which we are using?

Thanks and Regards,
Chanda.

Hello Chanda,

Please examine my previous post as the answer to your question is there:

I cannot confirm if the issue you report is an actual bug in your version or the problem stems from something in the exact project

is the line I am referring to. Thus, my advise still stands - upgrading to the latest version is the approach I suggest.
