I have put in a RadComboBox control in a simple ASPX page and when I run it in DRIP tool, I see a lot of memory leaks. If I remove the combobox , then the memory leaks go away. Please advice if you have any fix for the leaks in Rad ASP.Net controls?
below is a simple ASPx snippet

1 grid with many rows (for scrolling), formdecorator and a checkbox on each row.
When you make a scroll and click at checkbox or radio button then page make scrolling or disappears.
If I avoid them from decorating everything is OK.
P.S For another controls this not happens
