(Windows only; GUI for .NET only)
The .NET event published when some user action initiates a sort operation in the bound .NET control (for example, clicking on a column header in a grid control).
You can use this event when the BindingSource object is bound to a query or a buffer. If bound to a ProDataSet object, this event applies only to the top-level table displayed in the .NET control.
Return type: VOID
Access: PUBLIC
Applies to: Progress.Data.BindingSource class
Delegate: Progress.Data.SortRequestEventHandler
The delegate for this event defines the following event handler signature:
EventHandlerName ( INPUT sender AS CLASS System.Object, INPUT args AS CLASS Progress.Data.SortRequestEventArgs ). |
When this event occurs, the event handler must reopen the query associated with the ABL data source object with a modified sort criteria based on the values specified in the SortRequestEventArgs object.
This event occurs only for .NET controls that rely on their data source for sorting.
