Need lazy load approach for treeview & wanted to maintain only viewing items in mem

Thanks, I will look into the link.

Edited : gone through the link, Looks like they have not fixed the bug instead they suggested to build 64-bit application, my application is 64 bit any how .

BTW: how did you do memory management in this case, As you have huge row & we need to build tree before population it onto view.
So did you manage the memory. did you create entire tree (items) and populate it or in some other way ??
