Examples

The following code example shows how to use the EditorAttribute attribute to associate the MenuItemCollectionEditor and UITypeEditor (the collection editor base class) classes with a property in a custom control, derived from the WebControl class, that gets and sets a MenuItemCollection collection.

private MenuItemCollection menuItems;

// Associate the MenuItemCollectionEditor with the Items. 
[Editor(typeof(System.Web.UI.Design.WebControls.
    MenuItemCollectionEditor),
    typeof(UITypeEditor))]
public MenuItemCollection Items
{
    get
    {
        // If there is no menuItems collection, create it.
        if (menuItems == null)
            menuItems = new MenuItemCollection();

        return menuItems;
    }
    set { menuItems = value; }
} // Items

Private menuItems As MenuItemCollection

' Associate the MenuItemCollectionEditor with the Items.
<EditorAttribute( GetType(System.Web.UI.Design.WebControls. _
    MenuItemCollectionEditor), _
    GetType(UITypeEditor))> _
Public Property Items() As MenuItemCollection
    Get
        If menuItems Is Nothing Then
            menuItems = New MenuItemCollection()
        End If
        Return menuItems
    End Get
    Set
        menuItems = value
    End Set
End Property ' Items

The EditValue method edits the values of the menu item collection of the associated Menu control. The GetEditStyle method gets the editing style that is associated with this editor.
