Using v2009.3.1314.35 with VS2008, IE8.

  1. On a blank page I put a RadScriptManager, a RadAjaxManager, and a RadListBox, leaving everything set to the default skin. 
  2. I add ten items to the list box via the Build RadListBox smart tag, all with the default text
  3. Set AutoPostBack to true
  4. Hook into the SelectedIndexChanged event, but do not add any code to the handler.
  5. Configure the ajax manager so that the list box updates itself.

Then I run the page and watch the memory allocation for iexplore.exe.  It starts out around 12megs.  

Every time I click one of the items in the list box, the memory allocation increases, and I can pretty quicky grow it to 20 megs before my finger gets tired.

Known issue?

Hi Louis,

We recently did some improvements to RadListBox' rendering, can you try if you can reproduce this issue with a more recent version of our suite? Thank you in advance.

All the best,
