I got VirtualQueryableCollectionView working with RadComboBox when VirtualizingStackPanel is used.

However, when filtering is enabled, the ComboBox would load all the items (batched in LoadSize) from the VirtualQueryableCollectionView before displaying the dropdown. Am I missing something here?

The combobox Xaml:
<telerik:RadComboBox ItemsSource="{Binding Items}"
                     SelectedItem="{Binding SelectedItem}"
                     DisplayMemberPath="Name"
                     IsFilteringEnabled="True"
                     TextSearchMode="Contains"
                     ClearSelectionButtonVisibility="Visible"
                     ClearSelectionButtonContent="Remove">
    <telerik:RadComboBox.ItemsPanel>
        <ItemsPanelTemplate>
            <VirtualizingStackPanel/>
        </ItemsPanelTemplate>
    </telerik:RadComboBox.ItemsPanel>
</telerik:RadComboBox>

Hi Wenrong,

Unfortunately virtualization with filtering is not supported in the current version of RadComboBox control.
