关于属性databindings

Question

  private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            string connString = @"
                 server=localhost;
                 integrated security=true;
                 database=northwind";            string sql = @"
                 select
                  *
                 from
                   employees";            SqlConnection conn = new SqlConnection(connString);
            SqlDataAdapter da = new SqlDataAdapter(sql, conn);
            DataSet ds = new DataSet();
            da.Fill(ds, "employees");            textBox1.DataBindings.Add        }
为什么在写vs中写databindings字体没有变蓝，是因为少引用命名空间了么？希望高人指点。

Answer 1

DataBindings?? 你打上点以后 出来吗？ 

Answer 2

textbox有这个属性？ 好像是datasource吧

Answer 3

为什么要变蓝呢
this.textBox1.Text 中的Text也是黑体
