我已经覆盖了窗口ListBox,以便在每个ListBoxItem中显示图像和一段文本,但我需要通过访问实际ListBox的DisplayMemberPath来过滤显示的文本内容我希望这样做我无法让它发挥作用。
<Setter Property="ItemContainerStyle">
<Setter.Value>
<!-- Simple ListBoxItem - This is used for each Item in a ListBox. The item's content is placed in the ContentPresenter -->
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Grid SnapsToDevicePixels="true">
<Border x:Name="Border">
<Grid Height="40">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Image
Source="{Binding Path=ThumbnailImage}"
Height="30"
Width="30"
Grid.Column="0"/>
<Label
x:Name="Text"
Content="{TemplateBinding DisplayMemberPath}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
VerticalContentAlignment="Center"
HorizontalAlignment="Stretch"
Grid.Column="1"
Height="40"/>
</Grid>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter Property="FontWeight" Value="Bold" TargetName="Text"/>
<Setter Property="Foreground" Value="White" TargetName="Text"/>
<Setter Property="Background" Value="Blue" TargetName="Border"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Setter.Value>
</Setter>
这是我用于我的风格的代码,这是我无法工作的代码:
Content =“{TemplateBinding DisplayMemberPath}”
抱怨: 在类型'ListBoxItem'
上找不到静态成员'DisplayMemberPathProperty'有人能指出我正确的方向吗?
答案 0 :(得分:0)
没关系,我现在从ListBox获得了值,我需要做的就是将它转换为从itemssource中的dataobject获取我需要的属性。
以防有人想知道代码:
Content="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=ListBox}, Path=DisplayMemberPath}"
