+Summary: Using TableStyles with Datagrid fails
+
+Description of Problem:
+When using Tablestyles in the DataGrid an exception is thrown.
+
+Steps to reproduce the problem:
+1. Compile the following:
+
+using System;
+using System.Drawing;
+using System.Windows.Forms;
+using System.Data;
+
+namespace TableStyleTest
+{
+	class Form1 : Form						
+	{
+		static void Main() 
+		{
+			Application.Run(new Form1());
+		}
+
+		public Form1()		 
+		{
+			DataGrid grd = new DataGrid();
+			grd.Size = new Size(200,200);
+			this.Controls.Add(grd);
+
+			DataTable tb = new DataTable("TestTable");
+			tb.Columns.Add("Col1");
+			tb.Rows.Add(new string[] {"row 1"} );
+			tb.Rows.Add(new string[] {"row 2"} );
+			tb.Rows.Add(new string[] {"row 3"} );
+
+			DataGridTableStyle ts = new DataGridTableStyle();
+			ts.MappingName = "TestTable";
+
+			DataGridTextBoxColumn txt = new 
+DataGridTextBoxColumn();
+			txt.MappingName = "Col1";
+			txt.HeaderText = "Column 1";
+			ts.GridColumnStyles.Add(txt);
+
+			grd.TableStyles.Add(ts);
+
+			grd.DataSource = tb;
+		}		
+	}
+}
+
+2. Run with Mono in Linux
+
+Actual Results:
+System.NullReferenceException
+
+Expected Results:
+Loading the form and displaying the grid just as in Windows/MS.NET
+
+How often does this happen? 
+Always
+
+Additional Information:
+Tested in Ubuntu 6.06 with Mono from SVN as of today.
