(Windows only; GUI
for .NET only)
The .NET event published when the value of
the Position property (which specifies the position
of the current row in the bound .NET control) changes, based either
on some user action in the .NET control or a programmatic action.
For example:
- The user clicks on a different row in a
control.
- The user clicks on a Next button and
the event handler for the button increments the Position property
value.
Note: When you click on a child row,
the Position property is set to the position of
the corresponding top-level parent row.
Return type: VOID
Access: PUBLIC
Applies
to:
Progress.Data.BindingSource class
Delegate:
System.EventHandler
Syntax
The
delegate for this event defines the following event handler signature:
EventHandlerName
(
INPUT sender AS CLASS System.Object,
INPUT args AS CLASS System.EventArgs
).
|
-
EventHandlerName
- The name of the event handler.
-
sender
- Object reference to the BindingSource object
instance that published the event.
-
args
- Object reference to a .NET System.EventArgs object
instance containing arguments for the event. For information on
the public class members inherited from the System.EventArgs class, refer
to the .NET Framework class library.
Whenever
the value of the Position property changes, the BindingSource object
automatically synchronizes the buffer in the bound ABL data source
object to correspond to the selected row in the bound .NET control.
Note: Generally, you should change the Position property,
rather than navigating or repositioning the query associated with
the bound ABL data source object. For more information about synchronizing
data, see OpenEdge Development: GUI for .NET Programming.
