清除所有asp：TreeView复选框

Question

清除所有asp:TreeView复选框以便它们全部未被选中的最佳方法是什么？我尝试了迭代treenodes并取消选中，但这不适用于子节点复选框。

你自己的答案很接近，但不会遍历树。尝试像这样的递归方法。

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 

你的初始呼叫应该是这样的：

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