Question

I have the following in code behind:

[WebMethod]
public static string GenerateHtml(string id)
{
    //return id;
    DataView vwMain2;
    try
    {
        DbProviderFactory dbf = DbProviderFactories.GetFactory();
        using (IDbConnection con = dbf.CreateConnection())
        {
            string sSQL;
            sSQL = "select top 20                " + ControlChars.CrLf
                 + " ASSISTING_FILE_ID, DATE_ENTERED, CLIENT_CLAIM_NUM, PRIMARY_INSURED, PRIMARY_CLAIMANT, LOB_ID, FILE_STATUS, BRANCH_NAME," + ControlChars.CrLf
                 + " OWNERS_FIRST_NAME, OWNERS_LAST_NAME, OWNERS_NAME, OWNERS_EMAIL, OWNERS_OFFICE_PHONE, OWNERS_FAX_PHONE, OWNERS_CELL_PHONE" + ControlChars.CrLf
                 + "  from vwFILES_DetailViewWithOwners" + ControlChars.CrLf
                 + " where 1 = 1                    " + ControlChars.CrLf;
            //+ " where 1 = 1 and WEB_USER_ID = '" + Security.USER_ID.ToString() + "'" + ControlChars.CrLf;
            using (IDbCommand cmd = con.CreateCommand())
            {
                cmd.CommandText = sSQL;

                using (DbDataAdapter da = dbf.CreateDataAdapter())
                {
                    ((IDbDataAdapter)da).SelectCommand = cmd;
                    using (DataTable dt = new DataTable())
                    {
                        da.Fill(dt);
                        vwMain2 = dt.DefaultView;
                        GridView2.DataSource = vwMain2;

                            GridView2.DataBind();

                    }
                }
            }
        }
    }
    catch (Exception ex)
    {
        SplendidError.SystemError(new StackTrace(true).GetFrame(0), ex.Message);
        //lblError.Text = ex.Message;
    }

}

I want to loop through that and create an HTML table in the following format:

<table>
    <tbody>
        <tr>
            <th>Column Header</th>
        </tr>
        <tr>
            <td>Column Data</td>
        </tr>
    </tbody>
</table>

What is the best way to do this? I want to return the HTML once it is generated.

Thank you.

I’d just use a stringBuilder and piece together the HTML by hand in some loops.

StringBuilder sb = new StringBuilder();

sb.append('<table><tbody>');

foreach(DataRow r in dt.Rows)
{
     sb.append('<tr><th>' + r["ColumnHeader"] + '</th></tr>');
     sb.append('<tr><th>' + r["ColumnData"] + '</th></tr>');
}

 sb.append('</tbody></table>');


  return sb.ToString();
