Question

I am Using Visual Studio 2008.
I am trying to print all the data from a table in html formatted table
I am getting only the first row from Database printed but I want all the data to be printed on the screen.
See the code I have written.
Please help me out.

 public void cj()
{
    connString = "Data Source=CJ-PC;Initial Catalog=Electro;Integrated Security=True";
    using(con = new SqlConnection(connString))
    {
        con.Open();
        string sqlQuery = "Select * from CUSTOMER_DETAIL";
        using(cmd = new SqlCommand(sqlQuery,con))
        {
            using (sdr = cmd.ExecuteReader())
            {
                using (DataTable dt = new DataTable())
                {
                    dt.Load(sdr);
                    PlaceHolder1.Controls.Add(new LiteralControl("<table style='border:solid 2px Red; width:600px;'>"));
                    PlaceHolder1.Controls.Add(new LiteralControl("<tr>"));
                    int i = 0;
                    foreach (DataColumn dc in dt.Columns)
                    {
                        i++;
                        Label myLabel = new Label();
                        myLabel.ID = Convert.ToString(i);                            
                        PlaceHolder1.Controls.Add(new LiteralControl("<td style='border:solid 2px Blue;'>"));
                        myLabel.Text = "" + dc.ToString();
                        PlaceHolder1.Controls.Add(myLabel);
                        PlaceHolder1.Controls.Add(new LiteralControl("</td>"));
                    }
                    PlaceHolder1.Controls.Add(new LiteralControl("</tr>"));

                    PlaceHolder1.Controls.Add(new LiteralControl("<tr>"));
                    int j = 0;
                    foreach (DataRow dr in dt.Rows)
                    {                           
                        if(j < dt.Columns.Count)
                        {
                            Label myLabel = new Label();
                            myLabel.ID = Convert.ToString(i);
                            PlaceHolder1.Controls.Add(new LiteralControl("<td style='border:solid 2px aqua;'>"));
                            myLabel.Text = "" + dr[j].ToString();
                            PlaceHolder1.Controls.Add(myLabel);
                            PlaceHolder1.Controls.Add(new LiteralControl("</td>"));
                        }
                        j++;
                    }
                    PlaceHolder1.Controls.Add(new LiteralControl("</tr>"));
                    PlaceHolder1.Controls.Add(new LiteralControl("</table>"));
                }                           
            }
        }

problem is in your code when bind columns each of the row

you should add do while for append columns of the rows.
this function should be work according to your logic :

      foreach (DataRow dr in dt.Rows)
                {
                    PlaceHolder1.Controls.Add(new LiteralControl("<tr>"));      
                     int k = 0;
                     do
                      {
                        Label myLabel1 = new Label();
                        myLabel1.ID = Convert.ToString(k);
                        PlaceHolder1.Controls.Add(new LiteralControl("<td style='border:solid 2px aqua;'>"));
                        myLabel1.Text = "" + dr[k].ToString();
                        PlaceHolder1.Controls.Add(myLabel1);
                        PlaceHolder1.Controls.Add(new LiteralControl("</td>"));
                        k++;
                      } while (k < dt.Columns.Count);
                     PlaceHolder1.Controls.Add(new LiteralControl("</tr>"));    
                }
