Binding

Hi,
I should do binding for datagrid dynamically at code.I wrote the code as below. When I debug this code block ,it seems that it does bindings correctly, but grid comes with no columns on form.

MyClass myInstance=new MyClass ();
                   dataGridObject=new DataGrid();
                   dataGridObject.Width = 200;
                   dataGridObject.Height = 200;
                   binding = new Binding();
                   binding.Source = myInstance;
                   foreach (PropertyInfo prop in myInstance.GetType().GetProperties())
                   {
                       binding.Path = new PropertyPath(prop.Name);
                       DataGridTextColumn column=new DataGridTextColumn();
                       column.Header = prop.Name;
                       column.Binding=new Binding(prop.Name);
                       dataGridObject.Columns.Add(column);
                   }

 dataGridObject.ItemSource=myInstanceList;

Why does't come grid with columns, although I did necessary bindings?
Thanks for the replies in advance..
