    I have a RadComboBox that is bound to a collection of about 1500 items. The ComboBox is searchable with filtering.

    Everything was working as expected, except it was really slow to load.

    I Added the VirtualizingStackPanel and this gave me the speed required for the app and text searching is working. However, the ComboBox is no longer filtering the results.

    Here is my code:

    <telerik:RadComboBox Grid.Column="1"
                         ItemsSource="{Binding Fields}"
                         SelectedItem="{Binding SelectedField.Field, Mode=TwoWay}">
                            <VirtualizingStackPanel />

    I'm using the latest version of the control (Q2 2010 SP1).

    Any help would be greatly appreciated.

    Hi Jimmie,

    Thank you for contacting us.

    Unfortunately, virtualization and filtering are not supported together. We will do our best to improve this behaviour in one of our future releases.
    Sorry for the caused inconvenience.

    If you have any other questions about our controls please let us know.

    Sincerely yours,
    the Telerik team
