I've read around about memory leak and infragistics control.
Just wanted to know if the issue was fixed. If so, from what release was it fixed.
We are using 2008.2 and are experiencing the memory leak issue.
We'll need more specific information to investigate further. At a minimum, we'll need to know what platfrom and what control(s) are in use.
I recommend that you submit a support request to provide these details, and so that a Developer Support Engineer can investigate your issue.
