如何布局是在App.xaml中定义源码如下

				?

									<Application x:Class="CWebsSynAssistant.App"

									  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

									  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

									  xmlns:effect="clr-namespace:GrayscaleEffect;assembly=GrayscaleEffect"

									  StartupUri="Window1.xaml">

									  <Application.Resources>

									    <!-- ListView的布局模板-->

									    <ControlTemplate x:Key="myLVTemplate" TargetType="{x:Type ListView}">

									      <Grid>

									        <ScrollViewer x:Name="ScrollViewerElement"

									            Background="White"

									            VerticalScrollBarVisibility="Auto"

									            HorizontalScrollBarVisibility="Disabled">

									          <ItemsPresenter>

									          </ItemsPresenter>

									        </ScrollViewer>

									      </Grid>

									    </ControlTemplate>

									    <!-- ListViewItem的布局模板-->

									    <DataTemplate x:Key="myLVItemTemplate">

									      <Grid Name="myGrid" Width="70" Margin="8,8,0,0">

									        <Grid.RowDefinitions>

									          <RowDefinition Height="Auto"></RowDefinition>

									          <RowDefinition Height="Auto"></RowDefinition>

									        </Grid.RowDefinitions>

									        <Image Name="img" Source="{Binding Path=ISource}" HorizontalAlignment="Center"

									            Width="32" Height="32" Stretch="UniformToFill"

									            ToolTip="{Binding Path=FullFileName}" >

									          <Image.Effect>

									            <effect:GrayscaleEffect x:Name="grayscaleEffect" DesaturationFactor="1.0"/>

									          </Image.Effect>

									        </Image>

									        <TextBlock Name="imgTitle" Text="{Binding Path=FileName}" Grid.Row="1" HorizontalAlignment="Center"

									              FontSize="10" FontFamily="Arial"

									              ToolTip="{Binding Path=FullFileName}" Margin="4,4,4,4" TextTrimming="CharacterEllipsis" />

									      </Grid>

									      <DataTemplate.Triggers>

									        <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,

									          AncestorType={x:Type ListViewItem}}, Path=IsSelected}" Value="True">

									          <Setter TargetName="myGrid" Property="Background" Value="White"/>

									          <Setter TargetName="imgTitle" Property="Background" Value="CadetBlue"/>

									          <Setter TargetName="imgTitle" Property="Foreground" Value="White"/>

									          <Setter TargetName="img" Property="Effect">

									            <Setter.Value>

									              <effect:GrayscaleEffect DesaturationFactor="0.5"/>

									            </Setter.Value>

									          </Setter>

									          <!--

									          <Setter TargetName="img" Property="Opacity" Value=".5"></Setter>

									          -->

									        </DataTrigger>

									      </DataTemplate.Triggers>

									    </DataTemplate>

									    <!--下面这段代码不用，选中的时候边框有些边会变成蓝色（不是你希望的颜色）-->

									    <Style TargetType="{x:Type ListViewItem}" x:Key="ItemContainerStyle">

									      <Setter Property="Template">

									        <Setter.Value>

									          <ControlTemplate TargetType="{x:Type ListViewItem}">

									            <Border x:Name="Bd" Background="{TemplateBinding Background}"

									                BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="0" >

									              <ContentPresenter/>

									            </Border>

									            <ControlTemplate.Triggers>

									              <Trigger Property="IsSelected" Value="true">

									                <Setter Property="Background" TargetName="Bd" Value="White"/>

									              </Trigger>

									            </ControlTemplate.Triggers>

									          </ControlTemplate>

									        </Setter.Value>

									      </Setter>

									    </Style>

									  </Application.Resources>

									</Application>

如何引用在Windows1.xaml中定义源码如下

				?

									<ListView x:Name="listView1" ItemTemplate="{StaticResource myLVItemTemplate}"

									     Template="{StaticResource myLVTemplate}" ItemContainerStyle="{StaticResource ItemContainerStyle}"

									     Margin="0,4,0,4"  MouseDoubleClick="OnLocalFSOpen" Grid.Row="2">

									  <!--下面定义WarpPanel，使Item项在容器里从左到右从上到下排列-->

									  <ItemsControl.ItemsPanel>

									    <ItemsPanelTemplate>

									      <WrapPanel/>

									    </ItemsPanelTemplate>

									  </ItemsControl.ItemsPanel>

									</ListView>
