自定义视图，设置默认ListView,ListViewItems默认样式

public class VirtualStackPanelView : ViewBase

    {

        public static readonly DependencyProperty OrientationProperty =

            VirtualStackPanel.OrientationProperty.AddOwner(typeof(VirtualStackPanelView));

        }

        public static readonly DependencyProperty ItemTemplateProperty =

        public double ItemWidth

        {

        public HorizontalAlignment HorizontalContentAlignment

        {

            get { return (HorizontalAlignment)GetValue(HorizontalContentAlignmentProperty); }

            set { SetValue(HorizontalContentAlignmentProperty, value); }

        }

        public static readonly DependencyProperty CacheItemCountProperty =

            DependencyProperty.Register("CacheItemCount", typeof(int),

            typeof(VirtualStackPanelView), new UIPropertyMetadata(0));

            set { SetValue(CacheItemCountProperty, value); }

        }

        private GridViewColumnCollection _columns = new GridViewColumnCollection();

        public GridViewColumnCollection Columns

        protected override object DefaultStyleKey

        {

            get

            {

                return new ComponentResourceKey(GetType(), "virtualStackPanelViewDSK");

            }

        }

        protected override object ItemContainerDefaultStyleKey

        {

            get

            {

                return new ComponentResourceKey(GetType(), "virtualStackPanelViewItemDSK");

            }

        }

    }

查看ListView源码发现，当视图改变的时候,用当前视图的DefaultStyleKey，ItemContainerDefaultStyleKey设置ListView的默认样式和项容器样式，对于默认视图和我们自定义的视图

 public class ListView : ListBox

     {

         public static readonly DependencyProperty ViewProperty;

         private ViewBase _previousView;

         public ViewBase View

         {

             get

             {

                 return (ViewBase)base.GetValue(ListView.ViewProperty);

             }

             set

             {

                 base.SetValue(ListView.ViewProperty, value);

             }

         }

         static ListView()

         {

             ListView.ViewProperty = DependencyProperty.Register("View", typeof(ViewBase), typeof(ListView), new PropertyMetadata(new PropertyChangedCallback(ListView.OnViewChanged)));

             ListBox.SelectionModeProperty.OverrideMetadata(typeof(ListView), new FrameworkPropertyMetadata(SelectionMode.Extended));

         }

         private static void OnViewChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)

         {

             ListView listView = (ListView)d;

             ViewBase viewBase = (ViewBase)e.OldValue;

             ViewBase viewBase2 = (ViewBase)e.NewValue;

             if (viewBase2 != null)

             {

                 if (viewBase2.IsUsed)

                 {

                     throw new InvalidOperationException(SR.Get("ListView_ViewCannotBeShared"));

                 }

                 viewBase2.IsUsed = true;

             }

             listView._previousView = viewBase;

             listView.ApplyNewView();

             listView._previousView = viewBase2;

             ListViewAutomationPeer listViewAutomationPeer = UIElementAutomationPeer.FromElement(listView) as ListViewAutomationPeer;

             if (listViewAutomationPeer != null)

             {

                 if (listViewAutomationPeer.ViewAutomationPeer != null)

                 {

                     listViewAutomationPeer.ViewAutomationPeer.ViewDetached();

                 }

                 if (viewBase2 != null)

                 {

                     listViewAutomationPeer.ViewAutomationPeer = viewBase2.GetAutomationPeer(listView);

                 }

                 else

                 {

                     listViewAutomationPeer.ViewAutomationPeer = null;

                 }

                 listViewAutomationPeer.InvalidatePeer();

             }

             if (viewBase != null)

             {

                 viewBase.IsUsed = false;

             }

         }

         protected override void PrepareContainerForItemOverride(DependencyObject element, object item)

         {

             base.PrepareContainerForItemOverride(element, item);

             ListViewItem listViewItem = element as ListViewItem;

             if (listViewItem != null)

             {

                 ViewBase view = this.View;

                 if (view != null)

                 {

                     listViewItem.SetDefaultStyleKey(view.ItemContainerDefaultStyleKey);

                     view.PrepareItem(listViewItem);

                     return;

                 }

                 listViewItem.ClearDefaultStyleKey();

             }

         }

                 private void ApplyNewView()

         {

             ViewBase view = this.View;

             if (view != null)

             {

                 base.DefaultStyleKey = view.DefaultStyleKey;

             }

             else

             {

                 base.ClearValue(FrameworkElement.DefaultStyleKeyProperty);

             }

             if (base.IsLoaded)

             {

                 base.ItemContainerGenerator.Refresh();

             }

         }

       }

定义ListView和ListViewItem的样式，自定义视图里的DefaultStyleKey和ItemContainerDefaultStyleKey就是我们这里设置的样式

 <Style x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type uc:VirtualStackPanelView}, ResourceId=virtualStackPanelViewDSK}"

                                         TargetType="{x:Type ListView}"

设置我们的视图，在视图中定义我么的ItemTemplate样式，用于填充项容器的ContentPresenter的内容

 <uc:VirtualWrapPanelView x:Key="IconView"  ColumnHeaderContainerStyle="{StaticResource ColumnHeaderContainerStyle}"

                              ItemHeight="{Binding RelativeSource={RelativeSource AncestorType=uc:FileList2}, Path=ViewSize, Converter={StaticResource iac}}"

                              CacheItemCount=""

                              HorizontalContentAlignment="Left" >
