I doubt anyone will be able to provide you with an answer until you at least post your code, and details of the exception that's raised.

rough code is

displyreport()
{
viewste["report"]=lstReport;
}

I tried to use serilizable keyword on the top of class as well

InnerException = {"Error serializing value 'System.Collections.Generic.List`1[ActusLibrary.ObjectivesReport]' of type 'System.Collections.Generic.List`1[[ActusLibrary.ObjectivesReport, ActusLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]].'"}

Just the idea: view state storage is based on serialization. You can store any serializable object.
Please see:
