My data base table

abc                  sc123         Bcom
cef                  sc155         Bcom

C#

using (MySqlConnection myConnection = new MySqlConnection(constr))
{
     string oString = "Select * from euser_student WHERE  StudCourse=@StudCourse order by StudentFirstName  ASC";
     MySqlCommand oCmd = new MySqlCommand(oString, myConnection);

     oCmd.Parameters.AddWithValue("@StudCourse", StudCourse);   
     myConnection.Open();
     using (MySqlDataReader oReader = oCmd.ExecuteReader())
     {
          if (oReader == null || !oReader.HasRows)
          {
               ScriptManager.RegisterStartupScript(this, typeof(Page), "alert", "alert('No Student Found')", true);
          }
          else
          {
              while (oReader.Read())
              { 

              }
          }
          myConnection.Close();
     }               
}

You can use SqlDataReader.GetString Method to get the value of the specified column as a string Like this:

while (oReader.Read())
{
    TextBox1.Text = oReader.GetString(1); // 1 is the Parameter that is The zero-based column ordinal you can change it to what you want
    TextBox2.Text = oReader.GetString(2);
}

But If you want to show more than one row it would be better if you use a GridView control to show data. First add a GridView to your aspx like this:

<asp:GridView ID="GridView1" runat="server"></asp:GridView>

And then:

GridView1.DataSource = oReader;
GridView1.DataBind();
