It shouldn't close. You're probably re-loading it on postback.

Please check that you do NOT load the tree again when you do a postback. If you have to for some reason, then you have to remember last open or clicked node and select it manually, but if there is no reason to reload then don't.

treeview loads automatically on postback(when new page loads) .
By default it looses its state
