    {
        tv.Nodes.Clear();
        tv.Nodes.Add("<root>").Tag = o;
        tv.SelectedNode = tv.Nodes[0]; //it happens here
    });

推荐答案

TreeView 的句柄已经创建了吗?

Has the TreeView had its handle created yet?

您能否发布一个简短但完整的程序来演示这一点?

Could you post a short but complete program to demonstrate this?
