how autoupdate in gridview in OleDbDataAdapter in vb.net

Question

I use devexpress gridview only to view data how the connection can be autoupdate in case of an update in the source application. I used visual studio 2010. Is there the best solution or recommendation?

Dim cn = "provider=Microsoft.Jet.OLEDB.4.0; data source=" & Path & "; Extended Properties=dBase IV"
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.FillGridView()
    End Sub
    Private Sub FillGridView()
        Try
            dt = New DataTable
            Dim query = "select CODE,FILENAME1,FILENAME2,FILENAME3,SUBFOLDERP FROM ALPHABET"
            Using adapter As New OleDbDataAdapter(query, cn.ToString)
                adapter.Fill(dt)
            End Using
            Me.GridControl1.DataSource = dt
Catch myerror As OleDbException
            MessageBox.Show("Error: " & myerror.Message)
        Finally
        End Try
    End Sub
