清除所有asp：TreeView复选框

Question

清除所有asp:TreeView复选框以便不选中它们的最佳方法是什么？ 我尝试遍历treenodes并取消选中，但这不适用于子节点复选框。

您自己的答案很接近，但是不会遍历树。 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

您的初始通话将如下所示：

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