    Does anyone know why RadTreeView would take 1.5 seconds to postback in a page, when regular TreeView takes .5 seconds?  This doesn't happen in a simple demo project, just in my application page.  What might be in my page that would cause postback to get delayed?

    Thanks!

    Hi Andrew,

    Normally there shouldn't be any delay between postbacks. Does the delay occur on the client side (browser "hangs" for some time and then postbacks) or on the server side (page postbacks but it takes lots of time to load it back)? How many nodes does your treeview have? Also are you using load on demand and PersistLoadOnDemandNodes="true"?

    I actually get 2 page_load events on the server, and 2 nodeclick events, when clicking on a node.  Nodecheck event in this same tree does not have this problem.  The tree only has a few nodes (5).  I'm not using load on demand.  I am NOT subscribing to the nodeclick event twice.  Any ideas?

    Thanks!
