WPF中Listbox使用

在使用LsitBox这个控件的时候，如果添加数据绑定，只需要将要显示的结构体绑定到 ItemsSource 就可以将结构体成员显示出来。但如果结构体内有多项，而我们只想显示其中一项的话，可以这样

 <Style TargetType="ListBoxItem">

        <Setter Property="Foreground" Value="Black"/>

        <Setter Property="OverridesDefaultStyle" Value="True"/>

        <Setter Property="Height" Value="30"/>

        <Setter Property="FontSize" Value="16"/>

        <Setter Property="Template">

            <Setter.Value>

                <ControlTemplate TargetType="ListBoxItem">

                    <Border Name="back" BorderBrush="{x:Null}" Background="{x:Null}" BorderThickness="0,1,0,1">

                        <ContentPresenter Margin="2" VerticalAlignment="Center" Content="{Binding 结构体内成员名字}" />

                    </Border>

                </ControlTemplate>

            </Setter.Value>

        </Setter>

    </Style>

如果想给listbox添加类似鼠标移动到每一项的时候有一定的效果，可以在它的资源字典里直接添加字典，而在页面则不用给listbox控件作任何 类似stye={}；的东西，这一点比较特别，它好像全局变量一样，只要使用该资源字典，则Listbox 就会显示字典定义的效果。

贴一个常用的Listbox的资源字典

 1  <Style TargetType="ListBox">
 2 
 3         <Setter Property="BorderBrush" Value="Transparent"/>
 4 
 5         <Setter Property="BorderThickness" Value="1"/>
 6 
 7         <Setter Property="Background" Value="Transparent"/>
 8 
 9         <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Hidden"/>
10 
11         <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto"/>
12 
13         <Setter Property="ScrollViewer.CanContentScroll" Value="true"/>
14 
15         <Setter Property="VerticalContentAlignment" Value="Center"/>
16 
17 
18     </Style>
19 
20     <Style TargetType="ListBoxItem">
21         <Setter Property="Foreground" Value="#AEAEAE" />
22         <Setter Property="FontSize" Value="13" />
23         <Style.Triggers>
24             <Trigger Property="IsMouseOver" Value="True">
25                 <Setter Property="Background">
26                     <Setter.Value>
27                         <LinearGradientBrush StartPoint="1,0" EndPoint="0,1">
28                             <GradientStop Color="#FF013B48" Offset="0" />
29                             <GradientStop Color="#FF054C58" Offset="1" />
30                             <GradientStop Color="#FF2B809A" Offset="0.295" />
31                             <GradientStop Color="#FF287D96" Offset="0.68" />
32                         </LinearGradientBrush>
33                     </Setter.Value>
34                 </Setter>
35                 <Setter Property="Foreground" Value="White" />
36             </Trigger>
37 
38         </Style.Triggers>
39         <Style.Resources>
40             
41             <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="#00B4DF" Opacity=".4"/>
42             
43             <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="#00B4DF" Opacity=".4"/>
44         </Style.Resources>
45 
46     </Style>

再贴一个与上面若有重复的样式，但此样式包括在样式里绑定结构体成员的完整样式

 <!--ListBox样式-->

        <Setter Property="ScrollViewer.CanContentScroll" Value="true"/>

        <Setter Property="VerticalContentAlignment" Value="Center"/>

    </Style>

    <!--ListBoxItem样式-->

    <Style TargetType="ListBoxItem">
