DataGrid AutoSort and SingleRowSelection when DataSource is an ArrayList

Question

Hi,

I am using a DataGrid control on my form which is filled by an ArrayList. After that I clear DataGridTableStyle and add the customized one. But after adding DataGridTableStyle, the Grid's AutoSorting functionality does not work. Eventhough set AutoSort=true.

1. Can anybody tell me what to do to achieve AutoSorting by clicking on column header?
   
2. Also How may I restrict the users to Select Single row only?

Following is a small snippet of code I use:

1	// myArrayList is filled before with my Business Objects
2	this.dataGrid1.DataSource = myArrayList;
3
4	DataGridTableStyle t = new DataGridTableStyle ();
5	t.MappingName= "ArrayList";
6
7	DataGridTextBoxColumn c = new DataGridTextBoxColumn ();
8	c.MappingName = "Id";
9	c.HeaderText="ID";
10	t.GridColumnStyles.Add (c);
11
12	c =  new DataGridTextBoxColumn ();
13	c.MappingName = "Reference";
14	c.HeaderText="Reference";
15	t.GridColumnStyles.Add (c);
16
17	this.dataGrid1.TableStyles.Clear();
18	t.AllowSorting = true;
19	this.dataGrid1.TableStyles.Add (t);
