Refresh (re-execute query) a listview's data source (ASP.NET, VB)

I have a listview with a datasource configured for it on the aspx page.  I am making the listview visible and not visible at different times and need it to update when it becomes visible.

in my routine (in my aspx.vb file), I call this:
 ListView1.Visible = True

and I want it to refresh (re-execute query) at this time.

it was suggested that I use ListView1.refresh() or  ListView1.refresh both of which

give the error 'refresh' is not a member of system.web.UI.webcontrols.listview
