標籤：

treeView預設 展開

treeView1.ExpandAll();

treeview判斷點擊節點：

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)        {            if (treeView1.SelectedNode.Name == "節點名")            {                 frm_cluster.ShowDialog();            }｝

 treeview 點擊已經選過的節點如何觸發事件:

  private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)        {            if (treeView1.SelectedNode.Name == "cluster")            {                frm_cluster.ShowDialog();            }            treeView1.SelectedNode = null;        }

在AfterSelect事件的末尾處，添加：treeView1.SelectedNode = null;
