    I am using the DataboundListbox like so DataVirtualizationMode="OnDemandAutomatic", because I'm recieving the data from a server asynchronously, but I dont know how to invert the items going from bottom up like so: 

    My main problem is how to throw Datarequest event when on top of the list.

    Thanks in advance
    Best Regards

    Hi Doug,

    Thanks for contacting us.

    The OnDemandAutomatic virtualization mode implies that new items are added at the end of the scrollable list.
    I presume what you need here is the so called pull-to-refresh approach that allows you to insert new items at the beginning of the list. We have already prepared similar functionality in our listbox and it will be included in the Q2 2012 package of RadControls for Windows Phone. The pull-to-refresh approach allows the end user to request new data by pulling the scrollable list at its top end and releasing it. An event will be fired that will allow you to make a data request and load new data.

    I hope this helps.

    All the best,
