public event AfterMeasurementEventHandler AfterMeasurement
Public Event AfterMeasurement As AfterMeasurementEventHandler
The AfterMeasurement event's data class is AfterMeasurementEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs. |
| MapRuler | Returns the created ruler. |
The Measurements object raises the AfterMeasurement event after a user creates a ruler. To get the new ruler, use the e.MapRuler property. To cancel ruler creation, set the e.Cancel property to true.
The following example cancels area ruler creation:
private void Measurements_AfterMeasurement(object sender, AfterMeasurementEventArgs e) {
MapRuler ruler1 = e.MapRuler;
if (ruler1.RulerType == RulerType.Area) {
e.Cancel = true;
}
}
Private Sub Measurements_AfterMeasurement(ByVal sender As Object, ByVal e As AfterMeasurementEventArgs)
Dim ruler1 As MapRuler = e.MapRuler
If ruler1.RulerType Is RulerType.Area Then
e.Cancel = True
End If
End Sub
