我想知道人们是如何处理ListBox控件,有没有项目?例如我要绑定的搜索结果列表,但如果没有结果发现我想显示没有找到结果。
I was wondering how people handle a ListBox control that has no items? e.g. I want to bind a list of search results but if no results are found i would like to display "No results found".
我的样子当前解决。这是我隐藏列表框,如果结果集计数= 0,并显示有未找到结果消息的标签。我非常希望类似的ASP .NET的DataGrid EmptyTemplate解决方案。
The way i currently tackle this is that i hide the listbox if the result set count = 0 and show a label with the "No results found" message. Ideally i would like something like the ASP .NET datagrid EmptyTemplate solution.

推荐答案
我已经受够了这种code一定的成功:
I've had some success with this code:
<Style TargetType="ListBox" x:Key="ListStyle" BasedOn="{StaticResource {x:Type ListBox}}">
<Style.Triggers>
<DataTrigger
Binding="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=Items.Count}"
Value="0"
>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<TextBlock>No items to display</TextBlock>
</ControlTemplate>
</Setter.Value>
</Setter>
</DataTrigger>
</Style.Triggers>
</Style>
