我将treeview和数据库已经绑定,但是我需要一个效果.单击树控件中的节点,将对应的数值绑定到textbox中等输入文本控件中.
 public void GetText(string strId)
        {

            string cmd = "select * from FD_CadSet where cCadID='"+strId+"'";
            SqlConnection _Connection = new SqlConnection(SqlConn);
            _Connection.Open();
            SqlCommand com = new SqlCommand(cmd, _Connection);
            SqlDataReader dr = com.ExecuteReader();
            while (dr.Read())
            {
                this.txb_code.Text = dr[1].ToString();
                this.nu_week.Value = int.Parse(dr[6].ToString());
                this.tb_date.Text = dr[3].ToString();   //日期
                this.nu_day.Value = int.Parse(dr[2].ToString());
                this.tbx_bz.Text = dr[3].ToString();
            }
            dr.Close();
            _Connection.Close();
        
        }
  private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
        {
            GetText(treeView1.SelectedNode.Text.Substring(2));  //单击绑定
        }

就是这样,却怎么也达不到效果.

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
        {

           textBox1.Text = e.Node.Text.Trim();
}

在线等.哪位大师来说说啊

二楼的方法行不通
