Adding Controls to Datagrid in windows application

I am currently working on an application where I want to use DataGrid also.  One thing is that I do not have access to an ADO server, so I am forced to using the windows form to create a datagrid.  I am using VB.net 2003.   Can someone please lead me to the right direction.  thanks

I am able to create a datagrid using VB.net and the code is the following.  but what I plan to do is perform simple mathematical calculations based on  certain cell in the datagrid.  Can someone please help me how I can do this.  Any help on this is greatly appreciated,   thanks.



the code is shown below:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim dt As New DataTable
        dt.Columns.Add("X")
        dt.Rows.Add(New Object() {"A"})

        dg1.DataSource = dt
    End Sub
