You need to use Sessions and Postback in your code.

Any errors? Push F12 and see if it's denied access to the CR Viewer13 folder.

Typically you need to give IIS full read/write permission to this folder:

C:\inetpub\wwwroot\aspnet_client\system_web\4_0_30319\crystalreportviewers13

VS will use the IISExpress copy of it located here:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\ASP.NETClientFiles\crystalreportviewers13
