                SqlCommand cmd2 = new SqlCommand("SELECT [Item_Name],[Order_ID],[Price] FROM [Work_Lab].[dbo].[ItemOrderDetails]", con);
                //SqlDataReader dr = cmd2.ExecuteReader();
                SqlDataAdapter ds = new SqlDataAdapter(cmd2);
                DataTable dt = new DataTable();
                ds.Fill(dt);
                if (dt.Rows.Count > 0)
                {
                    Response.Output.Write("--------------------------<br/>");
                    Response.Output.Write("|Item Name|Order No|Price&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|<br/>");
                    Response.Output.Write("--------------------------<br/>");
                    foreach (DataRow row in dt.Rows)
                    {
                        string name = "|"+Convert.ToString(row["Item_Name"]).PadRight(8)+"|";
                        string orderId = Convert.ToString(row["Order_ID"]).PadRight(5)+"|";
                        string price = row["Price"].ToString() + "|<br/>";
                        Response.Output.Write(name);
                        Response.Output.Write(orderId);
                        Response.Output.Write(price);
                    }
                    Response.Output.Write("--------------------------");
                }
                con.Close();
            }

here this is my code.

Problem is...
while i save Item_Name value in string with padding it surely added padding in it...
e.g.
Original value = "Pen";
with padding = "Pen "; (with 4 white space);

but while i print this value with Response.Output.Print it doesn't take that white space ...
it directly print value without any white space.

how i can add white space in it?

Hope you understand what i want to ask.
