How to: Sort Filter Drop-Down Items in a Custom Manner

The following example demonstrates how to sort filter drop-down items in a custom manner.

In this example, the CustomFilterPopupItems event is handled to manage a list of filter items. This event is raised when an end-user invokes the filter drop-down. The event parameter provides access to the filter items list, which is then sorted by the length of the items' captions (if the corresponding option is selected).
