清除所有asp：TreeView复选框

Question

清除所有asp:TreeView复选框以便全部取消选中的最佳方法是什么？我已经尝试迭代treenodes并取消选中，但这对于子节点复选框不起作用。

你自己的答案很接近，但不会越过树。尝试这样的递归方法。

   Private Sub unCheckNodesIncludingDescendants(Node as TreeNode)
        Node.checked=false
        For Each tn As TreeNode In Node.ChildNodes
            tn.Checked = False
            unCheckNodesIncludingDescendants(tn)
        Next tn
    End Sub

您的初次通话将如下所示：

private sub UncheckWholeTree(TreeControl as TreeView)
    For each rootNode as TreeNode in TreeControl.nodes
      unCheckNodesIncludingDescendants(rootNode)
    Next rootNode
end sub
