本文實(shí)例講述了WPF的ListView控件自定義布局用法。分享給大家供大家參考，具體如下：

概要：

以源碼的形式貼出，免得忘記后，再到網(wǎng)上查資料。在VS2008+SP1環(huán)境下調(diào)試通過

引用的GrayscaleEffect模塊，可根據(jù)參考資料《Grayscale Effect...》中的位置下載。

如何布局是在App.xaml中定義源碼如下

<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>    <!--下面這段代碼不用，選中的時(shí)候邊框有些邊會(huì)變成藍(lán)色（不是你希望的顏色）-->    <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中定義源碼如下

<ListView x:Name="listView1" ItemTemplate="{StaticResource myLVItemTemplate}"     Template="{StaticResource myLVTemplate}" ItemContainerStyle="{StaticResource ItemContainerStyle}"     Margin="0,4,0,4"  MouseDoubleClick="OnLocalFSOpen" Grid.Row="2">  <!--下面定義WarpPanel，使Item項(xiàng)在容器里從左到右從上到下排列-->  <ItemsControl.ItemsPanel>    <ItemsPanelTemplate>      <WrapPanel/>    </ItemsPanelTemplate>  </ItemsControl.ItemsPanel></ListView>
