DataGridTableStyle.MappingNameChanged-Ereignis

Tritt ein, wenn sich der MappingName-Wert ändert.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

Syntax

'Declaration
Public Event MappingNameChanged As EventHandler
'Usage
Dim instance As DataGridTableStyle
Dim handler As EventHandler

AddHandler instance.MappingNameChanged, handler

public event EventHandler MappingNameChanged

public:
event EventHandler^ MappingNameChanged {
    void add (EventHandler^ value);
    void remove (EventHandler^ value);
}

/** @event */
public void add_MappingNameChanged (EventHandler value)

/** @event */
public void remove_MappingNameChanged (EventHandler value)

JScript unterstützt die Verwendung von Ereignissen, aber nicht die Deklaration von neuen Ereignissen.
