Important
This API is intended to be used with the legacy SchedulerStorage only. Starting with version 18.1, SchedulerStorage and all of its satellite storages are replaced with their updated versions.
You can use the FilterControl to display resources that meet specified conditions. To enable the control to filter resources contained within the SchedulerStorage, the FilterControl.SourceControl property should be set to the SchedulerStorage.Resources collection.
When the FilterControl begins creating a collection of columns which will be used to construct a logical expression (available via the FilterControl.FilterString property), the PrepareResourceFilterColumn event is raised for each added column. Handling this event enables you to substitute the column’s name with a custom text, or prepare a custom editor for specific value types. The column being added is available via the FilterColumn property of the event handler’s parameter.
