c# – 如何将分层数据绑定到WPF TreeView?
发布时间:2020-12-15 04:22:57 所属栏目:百科 来源:网络整理
导读:类型如下: class Category{ public string Name; public string Message; public ObservableCollectionCategory SubCategories;} 它会说5个类别,其中每个类别包含0(无)到3之间的子类别. 我知道如何将非分层数据绑定到WPF TreeView,但无法弄清楚分层数据值.

这是一个例子……
<!-- Create a TreeView,and have it source data from the AnimalCategories collection --> <TreeView ItemsSource="{x:Static local:Window1.AnimalCategories}"> <!-- Specify the template that will display a node from AnimalCategories. I.e.,one each for “Amphibians” and “Spiders” in this sample. It will get its nested items from the "Animals" property of each item --> <TreeView.ItemTemplate> <HierarchicalDataTemplate ItemsSource="{Binding Path=Animals}"> <!-- Display the AnimalCategory by showing it's Category string --> <TextBlock FontWeight="Bold" Text="{Binding Path=Category}" /> <!-- Specify the nested template for the individual Animal items that are within the AnimalCategories. E.g. “California Newt”,etc. --> <HierarchicalDataTemplate.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding Path=Name}"/> </DataTemplate> </HierarchicalDataTemplate.ItemTemplate> </HierarchicalDataTemplate> </TreeView.ItemTemplate> </TreeView> 这段代码来自here,对于你来说,阅读那篇文章可能会更有帮助,我在想.
