获取树视图节点的确切数据路径 [英] Getting exact datapath of a treeview node

问题描述

我正在将Treeview绑定到XMLDataSource，数据绑定是自动生成的，XML看起来像这样:-
< pre>
<乘客>
<乘客类型="normal"种族="asian">
< PassengerName> Name1</PassengerName>
</Passenger>
<乘客类型=普通">
< PassengerName> Name2</PassengerName>
</Passenger>
<乘客>
< PassengerName> Name3</PassengerName>
</Passenger>
</乘客>
</pre>


Treeview正确显示了XML，但是当我单击一个节点并且SelectedNodeChanged事件触发了SelectedNode.DataPath始终是列表中第一个乘客的路径，无论我单击哪个乘客节点.

有谁知道如何获取我单击的实际节点的数据路径?

I am binding a Treeview to an XMLDataSource, The databindings are being generated automaticaly, The XML looks like this:-
<pre>
<Passengers>
<Passenger type="normal" ethnic="asian">
<PassengerName>Name1</PassengerName>
</Passenger>
<Passenger type="normal">
<PassengerName>Name2</PassengerName>
</Passenger>
<Passenger>
<PassengerName>Name3</PassengerName>
</Passenger>
</Passengers>
</pre>


The Treeview displays the XML correctly but when i click on a node and the SelectedNodeChanged event fires the SelectedNode.DataPath is always the path to the first passenger in the list no matter which passenger node i click on.

Does anyone know how to get the datapath of the actual node i click on ?

推荐答案

您不能使用TreeNode的value属性存储索引的值吗?每个节点?然后，您可以使用此值对其进行跟踪.

祝你好运！

Couldn''t you use the value property of the TreeNode to store the index of each node? You can then track it down using this value.

Good luck!
