Error with C#: This XML file does not appear to have any style information associated with it.

Hello everyone,
I am currently trying to use DataTables in an application where I work. I am building the application using C# and ASP.NET, and am trying to make a DataTables user control that I can just add to any web page. I have most of it working, but I keep coming across this error whenever I try and generate the tables. It just hangs in the processing loop, and I had to open up the console in Chrome to find this error:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<string xmlns="http://tempuri.org/"&gt;
{"sEcho": "1","iTotalRecords": 8,"iTotalDisplayRecords": 8, "aaData": [ ALL OF MY TABLE ROWS ARE HERE ARE IN HERE...]}
</string>

Here is a link to a zipped folder of the solution: https://dl.dropboxusercontent.com/u/46643291/DataTableCSharp.zip. It is a VS2012 solution.
Here are the relevant pieces of code:

        protected void Page_Load(object sender, EventArgs e) {

            Table HeaderTable = new Table();
            HeaderTable.ID = "sampleTable";
            HeaderTable.CssClass = "widthFull fontsize10 displayNone";

            string tableName = "Table";
            string conString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Server.MapPath(string.Empty) + @"\App_Data\TestDB.accdb";
            string sqlString = "SELECT Table.* FROM [" + tableName +"]";

            adapter.Fill(ds);
            CreateHTMLTable(ds.Tables[0]);
            
        }


        private void WriteComment(String comment, HtmlTextWriter writer) {
            writer.Write("\n<!-- " + comment + " -->\n");
        }

            htable.Attributes.Add("class", "widthFull fontsize10 displayNone");
            htable.ID = "sampleTable";
            TableRow row = new TableRow();
            int count = 1;
            row.TableSection = TableRowSection.TableHeader;
            foreach (DataColumn column in table.Columns) {
                TableCell cell = new TableCell();
                cell.Text = column.ColumnName;
                row.Cells.Add(cell);
                if (count++ >= 5) break;
            }
            htable.Rows.Add(row);
            tableDiv.Controls.Add(htable);

    }
