For Each dr As DataRow In LoftDataSet.Services.Rows

Dim btn As New Button 'Instantiate a button
btn.Text = dr("service_name").ToString 'UserName is a field in my Users Table
btn.Size = New Size(60, 40)
btn.Tag = dr("ID") 'Here we set the tag to the primary key (ID)

'Since we're using a flowlayoutpanel, we don't need to worry about setting the location property
FlowLayoutPanel1.Controls.Add(btn) 'Add the button to the flow layout panel
AddHandler btn.Click, AddressOf UserClick 'Here we give the button a handler for the click event

Next
End Sub

'Here we write our method for the click event of the button(s) we created

Private Sub UserClick(ByVal sender As Object, ByVal e As EventArgs)

'We set a filter to the binding source passing it ID=<and whatever="" is="" stored="" in="" the="" tag="" property="">

ServicesBindingSource.Filter = "ID = " & DirectCast(sender, Button).Tag.ToString

End Sub
