Gridview did not appear

I did a code for a features where I uploaded the file and it will get saved into database and files folder (for filePath). But when I run and after uploaded the file, the gridview did not appear and showing the file that already uploaded. I tried turn to AutoGenerateColums=true and databind(). but the gridview still did not appear. What I'm doing wrong here?

this code for gridview design :

this is my code for gridview :

 protected void bind()
    {
        try
        {
            dbco();
            SqlCommand cmd = new SqlCommand("select * from ScheduleTable", con);
            SqlDataAdapter adp = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            adp.Fill(ds);
            SqlDataReader rd = cmd.ExecuteReader();
            if (rd.Read())
            {
                GridView1.DataSource = ds;
                GridView1.DataBind();

            }//end if
            else
            {
                ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());
                GridView1.DataSource = ds;
                GridView1.DataBind();
                int columncount = GridView1.Rows[0].Cells.Count;
                GridView1.Rows[0].Cells.Clear();
                GridView1.Rows[0].Cells.Add(new TableCell());
                GridView1.Rows[0].Cells[0].ColumnSpan = columncount;
                GridView1.Rows[0].Cells[0].Text = "No Record(s) Found";
            }//end else
        }//end try
        catch (Exception ex)
        {
            Response.Write(ex.Message);
        }//end catch
    }//end bind()
