AfterSortChange Event

Occurs after a sort action is completed.
Syntax
public event BandEventHandler AfterSortChange
Event Data

The event handler receives an argument of type BandEventArgs containing data related to this event. The following BandEventArgs properties provide information specific to this event.

PropertyDescription
Band The associated band (read-only).
Remarks

The bandargument returns a reference to an UltraGridBand object that can be used to set properties of, and invoke methods on, the band that was sorted. You can use this reference to access any of the returned band's properties or methods.

The UltraWinGrid can automatically sort the contents of columns without the addition of any code, provided the control is able to preload the rows in the band. Preloading is enabled by default if the recordset bound to the band contains less than 1000 rows. If you do not want to preload rows, but you still want to provide column sorting in the control, you must implement column sorting yourself using the BeforeSortChange and AfterSortChange events.

The BeforeSortChange event, which occurs before a sort action is completed, is generated before this event.

Example
Following code shows some of the information available in AfterSortChange event.
