Private Sub Button1_Click ( ByVal sender As System.Object , ByVal e As System.EventArgs ) Handles Button1.Click
Dim MyService As New localhost.Service1 ( )
DataGrid1.DataSource = MyService.Binding ( )
DataGrid1.DataMember = "Cust"
End Sub
Private Sub Button2_Click ( ByVal sender As System.Object , ByVal e As System.EventArgs ) Handles Button2.Click
Dim MyService As New localhost.Service1 ( )
Dim ds As DataSet = DataGrid1.DataSource
Dim dsChanges As DataSet = ds.GetChanges ( )
If Not ( dsChanges Is Nothing ) Then
ds.Merge ( MyService.Update ( dsChanges ) , True )
End If
