如何检查SelectedNode是TreeView中的父节点 [英] How to chek Selectednode is Parent node in treeview

问题描述

大家好，

我在asp.net中有treeview，我必须检查所选节点是否为父节点.

Hi all,

I have treeview in asp.net i have to check if selected node is parent.

 If TreeView1.SelectedNode = TreeView1.SelectedNode.Parent Then' this line generates error
            txtParentPhase.Text = ""
Else
     txtParentPhase.Text = TreeView1.SelectedNode.Parent.Text
End If

在此先感谢.

推荐答案

所选节点及其父节点如何相同?你的逻辑是错误的.如果要检查是否选择了节点，则必须检查SelectedNode是否为空(VB中没有).

How can a selected node and it''s parent be the same? Your logic is wrong. If you wish to check if a Node is selected or not, you have to check if the SelectedNode is null (Nothing in VB).
