直接用我這個得了：

Boolean bChildTrigger = true; Boolean bParentTrigger = true;private void tv_AfterCheck(object sender, TreeViewEventArgs e) {// MessageBox.Show("Node text: " + e.Node.Text);if (bChildTrigger){CheckAllChildren(e.Node, e.Node.Checked); }if (bParentTrigger){ CheckMyParent(e.Node, e.Node.Checked);} }void CheckAllChildren(TreeNode tn, Boolean bCheck) {bParentTrigger = false;foreach (TreeNode ctn in tn.Nodes){bChildTrigger = false; ctn.Checked = bCheck;bChildTrigger = true;CheckAllChildren(ctn, bCheck);}bParentTrigger = true; }void CheckMyParent(TreeNode tn, Boolean bCheck) {if (tn == null) return;if (tn.Parent == null) return;bChildTrigger = false;bParentTrigger = false;tn.Parent.Checked = bCheck;CheckMyParent(tn.Parent, bCheck);bParentTrigger = true;bChildTrigger = true; } 收獲園豆：50 回復(fù)?|?ArnoldZhang?|?大俠五級?|園豆：8874?|?2012-04-23 11:30

試了你的代碼.不行啊,點父節(jié)點的check 下面的子節(jié)點沒反應(yīng).

@荒野的呼喚:?你的代碼只要把tv_AfterCheak改成我的treeview控件名稱就可以了撒..其它位置不用改撒.我試了不行啊..
