    I have this combobox with is bound to List of customers around 5k customers

    <telerik:RadComboBox ClearSelectionButtonVisibility="Visible" ClearSelectionButtonContent="Clear Selection"
                                         ItemsSource="{Binding Customers}"  Margin="0 0 0 18"
                                         SelectedValue="{Binding CustomerId,Mode=OneWay}"
                                         Command="{Binding GetCustomerCommand}">
                                <VirtualizingStackPanel />



    I changed to virtualization and this helped in getting the list faster but when I added SelectedValue to bind to my viewmodel It is getting very very slow to load.

    Is there any way to overcome this problem ?
