清除所有asp：TreeView複選框

Question

清除所有asp:TreeView複選框以便它們全部未被選中的最佳方法是什麼？我嘗試了迭代treenodes並取消選中，但這不適用於子節點複選框。

你自己的答案很接近，但不會遍歷樹。嘗試像這樣的遞歸方法。

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 

你的初始呼叫應該是這樣的：

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