Fires after the value of the TrackBarControl.Value property has been changed.
[DXCategory("Action")] public event EventHandler ValueChanged
<DXCategory("Action")> Public Event ValueChanged As EventHandler
The ValueChanged event's data class is EventArgs.
The editor's ValueChanged event is equivalent to the RepositoryItemTrackBar.ValueChanged event available via the TrackBarControl.Properties object. Thus, adding/removing an event handler for the current event actually affects the RepositoryItemTrackBar.ValueChanged event.
