获取或设置一个值，该值指示在列表中添加或移除项时是否会引发 ListChanged 事件。

public:
 property bool RaiseListChangedEvents { bool get(); void set(bool value); };

public bool RaiseListChangedEvents { get; set; }

示例

下面的代码示例演示如何使用 RaiseListChangedEvents 方法。 有关完整示例，请参阅 BindingList<T> 类概述主题。

    // Declare a new BindingListOfT with the Part business object.
    BindingList<Part> listOfParts; 
    private void InitializeListOfParts()
    {
        // Create the new BindingList of Part type.
        listOfParts = new BindingList<Part>();

        // Allow new parts to be added, but not removed once committed.        
        listOfParts.AllowNew = true;
        listOfParts.AllowRemove = false;

        // Raise ListChanged events when new parts are added.
        listOfParts.RaiseListChangedEvents = true;

        // Do not allow parts to be edited.
        listOfParts.AllowEdit = false;
        
        // Add a couple of parts to the list.
        listOfParts.Add(new Part("Widget", 1234));
        listOfParts.Add(new Part("Gadget", 5647));
    }

' Declare a new BindingListOfT with the Part business object.
Private WithEvents listOfParts As BindingList(Of Part)

Private Sub InitializeListOfParts()

    ' Create the new BindingList of Part type.
    listOfParts = New BindingList(Of Part)

    ' Allow new parts to be added, but not removed once committed.        
    listOfParts.AllowNew = True
    listOfParts.AllowRemove = False

    ' Raise ListChanged events when new parts are added.
    listOfParts.RaiseListChangedEvents = True

    ' Do not allow parts to be edited.
    listOfParts.AllowEdit = False

    ' Add a couple of parts to the list.
    listOfParts.Add(New Part("Widget", 1234))
    listOfParts.Add(New Part("Gadget", 5647))

End Sub

注解

RaiseListChangedEvents如果要禁止ListChanged列表中发生事件，请将 属性false设置为 。
