在TreeView HierarchicalDataTemplate中显示子节点数 [英] Display number of children nodes in TreeView HierarchicalDataTemplate

问题描述

我试图显示TreeView的每个顶级节点中的子代数，但我不知道如何设置HierarchicalDataTemplate来显示每个节点的子代数.

I am trying to display the number of children in each toplevel node of a TreeView and I do not know how to setup the HierarchicalDataTemplate to display the number of children for each node.

推荐答案

嗨DwightKr，

Hi DwightKr,

如果relDevices_Sensors是一个IList，则可以绑定到其Count属性.

If relDevices_Sensors is an IList you can just bind to its Count property.

<TextBlock Foreground="White" Text="{Binding relDevices_Sensors.Count}"/>
