ListBox项模板中绑定ListBoxItem属性的方法

原文:ListBox项模板中绑定ListBoxItem属性的方法

<ListBox>

	<ListBox.ItemTemplate>

		<DataTemplate>

			<Grid Width="225"  Height="126" FocusVisualStyle="{x:Null}">

				<TextBlock

					x:Name="sortIndex"

					FontFamily="微软雅黑" FontSize="18" Foreground="Black"

					HorizontalAlignment="Left" VerticalAlignment="Top"

					Text="test"/>

			</Grid>

			<DataTemplate.Triggers>

				<DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={RelativeSource Mode=FindAncestor,AncestorLevel=1,AncestorType={x:Type ListBoxItem}}}" Value="True">

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

				</DataTrigger>

			</DataTemplate.Triggers>

		</DataTemplate>

	</ListBox.ItemTemplate>

</ListBox>

因为在数据模板中没办法找ListBoxItem的属性,所以需要用查找来找同级的对象,引用相对资源路径如下:

RelativeSource={RelativeSource Mode=FindAncestor,AncestorLevel=1,AncestorType={x:Type ListBoxItem}}
