    In my asp page i have RadPanelbar which contains 2 list boxes and 1 RadTreeview and 1 Checklistbox. Below RadPanelBar i have RadGrid, which get re sized based on panel expand and collapse. I noticed that after binding listbox and treeview with database. Panel Expand takes time in internet explorer. Even UI looks merged in between transition.(Check ScreenShot, It slow such a way that i can take screen shot very easily :( )

    Expand and collapse happening client side, so it's not doing trip to server during that operation, so why it takes time? It's all rendering time which is more in IE7?

    Let me know any way i can make it faster? I already checked Optimizing article, which doesn't have anything specific to RadPanelBar or RadListBox

    Hello Neha,

    Have you tried turning off the animation and see if that speeds things up. You just need to set None on the ExpandAnimation and CollapseAnimation properties.

    I hope that helps.
