在WPF Listbox中,我对这两个概念感到困惑: ItemTemplate和ItemContainerStyle 有人可以向我解释更多吗?
In WPF Listbox, I'm confused with these 2 notions: ItemTemplate and ItemContainerStyle Can someone explain me more?
推荐答案ItemTemplate 用于设计数据项内容的显示方式.您可以使用它来绑定数据字段,格式化显示字符串等等.它确定如何显示数据.
The ItemTemplate is for styling how the content of your data item appears. You use it to bind data fields, format display strings, and so forth. It determines how the data is presented.
ItemContainerStyle 用于设置数据项容器的样式.在列表框中,这将是一个ListBoxItem.此处的样式会影响选择行为或背景颜色.它确定显示器的样式和用户体验.
The ItemContainerStyle is for styling the container of the data item. In a list box, this would be a ListBoxItem. Styling here affects things like selection behavior or background color. It determines style and UX of the display.
上面链接的ItemContainerStyle的MSDN页面上有一个很好的示例,显示了一些区别:
The MSDN page for ItemContainerStyle, linked above, has a pretty good example showing some differences:
<!--Use the ItemTemplate to set a DataTemplate to define the visualization of the data objects. This DataTemplate specifies that each data object appears with the Proriity and TaskName on top of a silver ellipse.--> <ItemsControl.ItemTemplate> <DataTemplate> <DataTemplate.Resources> <Style TargetType="TextBlock"> <Setter Property="FontSize" Value="18"/> <Setter Property="HorizontalAlignment" Value="Center"/> </Style> </DataTemplate.Resources> <Grid> <Ellipse Fill="Silver"/> <StackPanel> <TextBlock Margin="3,3,3,0" Text="{Binding Path=Priority}"/> <TextBlock Margin="3,0,3,7" Text="{Binding Path=TaskName}"/> </StackPanel> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> <!--Use the ItemContainerStyle property to specify the appearance of the element that contains the data. This ItemContainerStyle gives each item container a margin and a width. There is also a trigger that sets a tooltip that shows the description of the data object when the mouse hovers over the item container.--> <ItemsControl.ItemContainerStyle> <Style> <Setter Property="Control.Width" Value="100"/> <Setter Property="Control.Margin" Value="5"/> <Style.Triggers> <Trigger Property="Control.IsMouseOver" Value="True"> <Setter Property="Control.ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=Content.Description}"/> </Trigger> </Style.Triggers> </Style> </ItemsControl.ItemContainerStyle>
