範例
下列程式代碼範例示範如何設定 AllowEdit 屬性。 如需完整的範例,請參閱 BindingList<T> 類別概觀主題。
// 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
備註
屬性 AllowEdit 通常由其他元件用來判斷是否允許編輯清單中的專案。 當 設定為新值時 AllowEdit , ListChanged 就會發生類型的 Reset 事件。
