BindingList<T>.AllowRemove Property

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

public bool AllowRemove { get; set; }

member this.AllowRemove : bool with get, set

Public Property AllowRemove As Boolean

true if you can remove items from the list with the RemoveItem(Int32) method otherwise, false. The default is true.

The following code example demonstrates how to set the AllowRemove property. For the complete example, see the BindingList<T> class overview topic.

    // 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

The AllowRemove property is typically used by other components to determine if the removal of items is allowed.

When AllowRemove is set to a new value, a ListChanged event of type Reset occurs.

• RemoveItem(Int32)
• AllowEdit
• AllowNew
