如何分隔在一个ItemsControl项目之间添加 [英] How can a separator be added between items in an ItemsControl
问题描述
我需要从一个集合中的项目控制显示数字的列表。这样的项目是:1,2,3
当他们被渲染,我需要他们用逗号(或类似的东西)隔开。因此,上述3项是这样的:1,2,3
我如何分隔添加到单个项目,没有一件上涨对列表的末尾?
我不停留在使用一个ItemsControl,但是这就是我已经开始使用。
<的ItemsControl的ItemsSource ={结合数字}>
< ItemsControl.ItemsPanel>
< ItemsPanelTemplate>
<! - 可以使用WrapPanel如果更适合您的方案 - >
< StackPanel的方向=横向/>
< / ItemsPanelTemplate>
< /ItemsControl.ItemsPanel>
< ItemsControl.ItemTemplate>
<&DataTemplate的GT;
< StackPanel的方向=横向>
< TextBlock的X:名称=commaTextBlock文本=/>
< TextBlock的文本={}绑定/>
< / StackPanel的>
< DataTemplate.Triggers>
< DataTrigger绑定={绑定的RelativeSource = {的RelativeSource previousData}}VALUE ={X:空}>
< setter属性=能见度的TargetName =commaTextBlockVALUE =折叠/>
< / DataTrigger>
< /DataTemplate.Triggers>
< / DataTemplate中> < /ItemsControl.ItemTemplate>
< / ItemsControl的>
我来到了你的问题,因为我一直在寻找在Silverlight的解决方案,它不具有previous数据相对源。
I'm needing to display a list of numbers from a collection in an Items Control. So the items are: "1", "2", "3".
When they are rendered, I need them separated by a comma (or something similar). So the above 3 items would look like this: "1, 2, 3".
How can I add a separator to the individual items, without having one tacked on the end of the list?
I am not stuck on using an ItemsControl, but that's what I had started to use.
<ItemsControl ItemsSource="{Binding Numbers}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<!-- could use a WrapPanel if more appropriate for your scenario -->
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock x:Name="commaTextBlock" Text=", "/>
<TextBlock Text="{Binding .}"/>
</StackPanel>
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource PreviousData}}" Value="{x:Null}">
<Setter Property="Visibility" TargetName="commaTextBlock" Value="Collapsed"/>
</DataTrigger>
</DataTemplate.Triggers>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
I arrived at your question because I was looking for a solution in Silverlight, which does not have a previous data relative source.
