Hi,

your not assign the DataSet to your DropDownList.

Please try this

C#

SqlCommand cmd = new SqlCommand("select * from user_login where groupid=1", cnn);
          SqlDataAdapter da = new SqlDataAdapter(cmd);
          DataSet ds = new DataSet();
          da.Fill(ds);
          ddlstudentname.DataSource=ds;
          ddlstudentname.DataTextField="name";
          ddlstudentname.DataVlaueField="name";
          ddlstudentname.DataBind();
