It allows you to store a lot of information in Sql Server&nbsp;without crating all the plumbing. There is a little glitch&nbsp;we just discovered. It Pet Shop 4 we&nbsp;allow user&nbsp;to have a shopping cart before sign in. Therefore when you sign in, we transfer the anonymous cart to the user cart:</P> <P class=MsoNormal>Global.asax code:<SPAN> <o:p></o:p></SPAN></P> <P class=MsoNormal><SPAN><o:p>&nbsp;</o:p></SPAN></P> <P class=MsoNormal><SPAN>void</SPAN><SPAN> Profile_MigrateAnonymous(<SPAN>Object</SPAN> sender, <SPAN>ProfileMigrateEventArgs</SPAN> e) {<o:p></o:p></SPAN></P> <P class=MsoNormal><SPAN><SPAN>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </SPAN><SPAN>ProfileCommon</SPAN> anonProfile = Profile.GetProfile(e.AnonymousID);<o:p></o:p></SPAN></P> <P class=MsoNormal><SPAN><SPAN>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </SPAN>Profile.ShoppingCart = anonProfile.ShoppingCart;<o:p></o:p></SPAN></P> <P><SPAN><SPAN>&nbsp;&nbsp;&nbsp; </SPAN>}<o:p></o:p></SPAN></P> <P>It works just fine. Now, when user checked out, we have to clear his/her cart, so we have to clear the cart in anonymous profile. We decided to destroy it on MigrateAnonymous event. Here’s the code:</P> <P class=MsoNormal><SPAN>void</SPAN><SPAN> Profile_MigrateAnonymous(<SPAN>Object</SPAN> sender, <SPAN>ProfileMigrateEventArgs</SPAN> e) {<o:p></o:p></SPAN></P> <P class=MsoNormal><SPAN><SPAN>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </SPAN><SPAN>ProfileCommon</SPAN> anonProfile = Profile.GetProfile(e.AnonymousID);<o:p></o:p></SPAN></P> <P class=MsoNormal><SPAN><SPAN>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </SPAN>Profile.ShoppingCart = anonProfile.ShoppingCart;<SPAN>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </SPAN><o:p></o:p></SPAN></P> <P class=MsoNormal><SPAN><SPAN>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </SPAN><o:p></o:p></SPAN></P> <P class=MsoNormal><SPAN><SPAN>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </SPAN>anonProfile.ShoppingCart = <SPAN>null</SPAN>;<SPAN>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </SPAN><o:p></o:p></SPAN></P> <P><SPAN><SPAN>&nbsp;&nbsp;&nbsp; </SPAN>}</SPAN></P> <P>Ouch – doesn’t work! User put an item in the cart, sign in, check out, cart is back!</P> <P>Lets try to clear it upon check out:</P> <P class=MsoNormal><SPAN>Profile<FONT color=#000000>.ShoppingCart.Clear();</FONT></SPAN></P> <P class=MsoNormal><SPAN>ProfileCommon</SPAN><SPAN> anonProfile = Profile.GetProfile(<SPAN>HttpContext</SPAN>.Current.Request.AnonymousID);<o:p></o:p></SPAN></P> <P><SPAN>anonProfile.ShoppingCart.Clear();</SPAN> <o:p></o:p></P> <P class=MsoNormal><o:p>&nbsp;</o:p></P> <P class=MsoNormal>Doesn’t work as well… </P> <P class=MsoNormal><o:p>&nbsp;</o:p></P> <P class=MsoNormal>It looks like a bug. Theoretically we should be able to destroy or recreate an anonymous profile on the fly.</P><img src="http://blogs.vertigosoftware.com/aggbug.aspx?PostID=872" width="1" height="1">1http://blogs.vertigosoftware.com/alexark/commentrss.aspx?PostID=872
