[Not supported by VpeWebControl, Interactive Edition and above]
A Field (not a control!) changed its value, because the associated Control was edited by the user or the content of any associated Control was changed by code.
This event is very interesting, because a Field will change its value each time the user makes a change. Evaluating this event means, that your application is informed about every single keystroke or mouse-click, which modifies a Control's content.
This is one of the few events where CloseDoc() may be called while processing the event.
The event is not fired, if you set the value of a Field by code.
VPEFieldEventHandler VPE.AfterFieldChange(
object sender,
VPEFieldEventArgs e
)
object sender
the VPE document object that fired the event
VPEFieldEventArgs e
event data, derived from EventArgs, one additional member:
public class VPEFieldEventArgs : EventArgs
{
public TVPEField Field; |
// the Field object that fired the event |
}
Remarks:
If you change the value of a Control by code, the AfterControlChange event is not fired. But if the Control is associated with a Field, the event AfterFieldChange is fired.
Vice versa, if you change the value of a Field by code, the AfterFieldChange event is not fired, but any Controls associated with the Field will fire the event AfterControlChange.
