After changing session state from InProc to custom Events are not getting fired while generating telerik report

[Payal]

Hi Team ,

We have recently changed session state from InProc to Custom in web.config (we want to work with Custom session state only). and after that  while generating telerik reports Events like ItemDataBound  ,ItemDataBind are not getting fired . 

We are using DLL version 15.1.21.616

Can someone please help with this issue ASAP ?
