Save data to ViewState

Question

I can tried save some data to ViewState, but i get this Error: Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Error serializing value 'HeRMeSSAAS.BussinesProcess.BussinesServices.CandidateService' of type 'HeRMeSSAAS.BussinesProcess.BussinesServices.CandidateService.' Code:

private IActionService ActionService
    {
        get
        {
            return ViewState["ActionService"] as IActionService;
        }
        set
        {
            ViewState["ActionService"] = value;
        }
    }

private void InitializeField(IActionService service)
        {
            ActionService = service;
        }

How i can store value to ViewState?

s your HeRMeSSAAS.BussinesProcess.BussinesServices.CandidateService decorated with the Serializable attribute?

eg:

[Serializable]
public class CandidateService
{

}

if this is not a very simple class I would also recommend storing it in the Session rather than the ViewState as it will take longer for the page to download and render

you need the [Serializable] Attribute on top of your business object.
