no, is actually an asp button inside a Listview asp.net 3.5 control



<asp:Button ID="btnPrint1" runat="server" Text="Print Selected Providers" onClientclick="javascript:CallPrint('form1')" />

'Button' is ambiguous , imported from the namespaces or types 'System.Windows.Forms,System.Web.UI.Controls'.

ok then try this

Dim mybtnPrint As System.Web.UI.Controls.Button = CType(ListView1.FindControl("btnPrint1"), System.Web.UI.Controls.Button)

or remove the System.Windows.Forms from the Import statement. it will work.
