    I'd seen this mentioned as an upcoming enhancement in the Q1 2011 ASP.NET controls... but I don't see it listed in the Beta documentation.  Is it going to be included?  I hope so as that is our #1 performance killer right now.

    Hi msigman,

    It is stil not included in the Beta version, but it will be included in the official release of Q1 2011 controls.

    Kind regards,

    That is great news!  Do we get any details on how the feature has been implemented or how it will work?

    This is a project I was planning on doing myself but I am relieved to know that Telerik has once again outdone themselves and added it.

    Hello msigman,

    Just a side note, you can implement your own load on demand even now, using the insertItems client-side method provided by RadListBox. In short you can use insertItems for the following:

    1) Obtain the needed  JSON data from the server using Ajax call
    2) Create new Telerik.Web.UI.RadListBoxItem items with the received JSON
    3) Bulk insert the created items using the insertItems method.
