If you are getting error on this that mean you don't have written this statement see below

use this

  SqlCommand cmd = new SqlCommand("Select * from Student_Master", con);

            SqlDataAdapter sda = new SqlDataAdapter(cmd);

            DataSet ds = new DataSet();

            sda.Fill(ds);

            Repeater1.DataSource = ds;

            Repeater1.DataBind();
