Solution 2

Use this function to your required event

C#

private void loadData()
 {

         SqlCommand cmd = default(SqlCommand);
         SqlConnection con = default(SqlConnection);
         con = new SqlConnection("<your connection="" string="" here=""></your>");
         con.Open();
         cmd = new SqlCommand("<your query="" here=""></your>", con);
         SqlDataReader reader = cmd.ExecuteReader();
         TestBox1.Text = Convert.ToString(reader["<column name="" here=""></column>"]);
         con.Close();
  }
