public event RoutedEventHandler BoundDataChanged

VB.NET

Public Event BoundDataChanged As RoutedEventHandler

Event Data

The BoundDataChanged event's handler receives an argument of the RoutedEventArgs type. The following properties provide information specific to this event:

Property	Description
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance.
Source	Gets or sets a reference to the object that raised the event.

Remarks

You can handle this event to change the way in which chart data is plotted before the chart displays it. In particular, this event can be used to change any properties of series labels or a series type, e.g. when series template data binding is used.

Note that not all properties can be changed in the BoundDataChanged event handler. For example, changing the following properties will have no effect.

• Series.ArgumentScaleType and Series.ValueScaleType;
• Series.ArgumentDataMember and Series.ValueDataMember;
• Series.Points.
