Binding business object (arraylist) with datagrid

I have one business class

Public Class Firm
Dim _FirmID As Integer
Dim _FirmName As String
Public Property FirmID() As Integer
Get
Return _FirmID
End Get
Set(ByVal value As Integer)
_FirmID = value
End Set
End Property
Public Property FirmName() As String
Get
Return _FirmName
End Get
Set(ByVal value As String)
_FirmName = value
End Set
End Property
End Class
i am binding arraylist of objFirms - i am able to bind it. BUT question is sequence of fields are not correctly displayed in datagrid. i grid they are displayed like following

1. Firmname 2. FirmID

You have to sort the array before you bind it. However there is no way to tell how your class Firm is ordering. Therefore you have to implement your own comparison function, e.g.

Class Firm : System.Collection.IComparer
{
...
public int Compare(object x, object y)
{
// write your comparison result here
}
}

After that, you can use the sort function, e.g.

ArrayList a = new ArrayList();
... // add your firm class here

a.Sort();

i am not talking about record sorting but column sequence (firm id should come first then firm name should come)
