+Summary: Datagrid TableStyle work incorrectly 
+
+Description of Problem:
+I'm using DataGrid with DataTable dynamically created. At first you call
+PrepareDataTable method, and then SetDataGridStyle.
+In TableStyle there are defined only 3 columns, so 2 of them should be not
+visible, but I've noticed that mono add automatically rest of columns. So
+after invocation of this code, I have datagrid with: Column 1, Column 2,
+Column 3, Column 4, Column 5, but I wanted Column 1, Column 2, Column 3.
+
+Steps to reproduce the problem, use this code:
+// -- CODE --
+using System;
+using System.Drawing;
+using System.Windows.Forms;
+using System.Data;
+
+namespace datagrid_test
+{
+	public class MainForm : System.Windows.Forms.Form
+	{
+		private System.Windows.Forms.Button button1;
+		private System.Windows.Forms.DataGrid dataGrid1;
+		
+		private DataTable m_someDataTable;
+		
+		public MainForm()
+		{
+			InitializeComponent();
+			
+			PrepareDataTable();
+			SetDataGridStyle();
+		}
+		
+		[STAThread]
+		public static void Main(string[] args)
+		{
+			Application.Run(new MainForm());
+		}
+		
+		#region Windows Forms Designer generated code		
+		private void InitializeComponent()
+		{
+			this.dataGrid1 = new System.Windows.Forms.DataGrid();
+			this.button1 = new System.Windows.Forms.Button();
+			((System.ComponentModel.ISupportInitialize)(this.dataGrid1)).BeginInit();
+			this.SuspendLayout();
+			// 
+			// dataGrid1
+			// 
+			this.dataGrid1.DataMember = "";
+			this.dataGrid1.HeaderForeColor = System.Drawing.SystemColors.ControlText;
+			this.dataGrid1.Location = new System.Drawing.Point(8, 4);
+			this.dataGrid1.Name = "dataGrid1";
+			this.dataGrid1.Size = new System.Drawing.Size(524, 152);
+			this.dataGrid1.TabIndex = 0;
+			// 
+			// button1
+			// 
+			this.button1.Location = new System.Drawing.Point(12, 168);
+			this.button1.Name = "button1";
+			this.button1.TabIndex = 1;
+			this.button1.Text = "button1";
+			this.button1.Click += new System.EventHandler(this.Button1Click);
+			// 
+			// MainForm
+			// 
+			this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
+			this.ClientSize = new System.Drawing.Size(540, 203);
+			this.Controls.Add(this.button1);
+			this.Controls.Add(this.dataGrid1);
+			this.Name = "MainForm";
+			this.Text = "MainForm";
+			((System.ComponentModel.ISupportInitialize)(this.dataGrid1)).EndInit();
+			this.ResumeLayout(false);
