At this point in time, no server supports this control. A virtual list box is typically a graphical user interface that displays a long list of entries with a few entries visible.
End users can display different sections of the list by scrolling up or down.
To display the list of entries, the client usually does not retrieve the entire list of entries from the server. Instead, the client just retrieves the subset of entries to be displayed to the end user. The virtual list view control provides the means for your client to request and retrieve certain subsets of a long, sorted list of entries. For example, a virtual list view control might specify that you want to retrieve entries 15 through 24 in a list of 100 results with entry 20 being the selected entry. Get 5 entries before the selected entry in the list.
