Datalist nested repeater Error

More buttons are originally used <asp: hyperlink>, but the error "cannot use the leading .. exit from the top-level directory" is changed to <asp: imagebutton>.

<Asp: imagebutton id = "hlinktopic" runat = "server" commandname = "linkbtn" commandargument = '<% # BIND ("productid ") %> 'visible = "false" imageurl = "images/movelast.gif"/>

Note that commandargument = '<% # BIND ("productid") %>' must be 'and cannot be ""
