asp.net 2.0 treeview点击相应的父节点文本展开子节点而不是点前面的加号才能打开

在子节点上设置:SelectAction为Expand;Expand为false

注意不是树控件上

示例代码:

        TreeNode t1 = new TreeNode();         t1.SelectAction = TreeNodeSelectAction.Expand;

t1.Expand=false;        t1.Text = "新加";         TreeNode t2 = new TreeNode();         t2.Text = "新加下";         t1.ChildNodes.Add(t2);         TreeView1.Nodes.Add(t1);
