推荐答案

通过使用ItemSource属性，你可以将treeview绑定到Observable集合

例如： -

By using ItemSource property you can bind treeview to Observable collection
For Eg:-

<treeview itemssource="{x:Static local:Window1.AnimalCategories}">

   <treeview.itemtemplate>
     <hierarchicaldatatemplate itemssource="{Binding Path=Animals}">

       <textblock fontweight="Bold" text="{Binding Path=Category}" />

       <hierarchicaldatatemplate.itemtemplate>

         <datatemplate>

           <textblock text="{Binding Path=Name}" />

         </datatemplate>
       </hierarchicaldatatemplate.itemtemplate>

     </hierarchicaldatatemplate>

   </treeview.itemtemplate>

 </treeview>

您好。如果在后面的代码中定义ObservableCollection，则必须为treeView设置x：name并在其加载的事件中写入：



private void myTreeView_Loaded（object sender，RoutedEventArgs e ）

{

myTreeView.DataContext = this.DataContext;

}



和你的xaml中的ItemsSource：

ItemsSource ={Binding}



GoodLuck。

Hi. if you define your ObservableCollection in code behind, you must set x:name for your treeView and in its loaded event write:

private void myTreeView_Loaded(object sender,RoutedEventArgs e)
{
myTreeView.DataContext=this.DataContext;
}

and in your xaml set ItemsSource :
ItemsSource="{Binding}"

GoodLuck.
