End-User Accessability define sortting && Localization

[Ubuntu]

Dear All,

    I have two questions:

    1st: End-user accessability
    ======
    I want to know if it is possible by any mean to give the end-user the ability to define the sort criteria to the generated report or not.
    I will appreciate any solution, as I couldn't find any by myself...
    
    2nd: Localization
    ======
    a. How should I localize the report contents
    b. I have a global switching of the language and it is working fine, except for the reportviewer ...I need to reload the reportviewer itself 
    to take the effect of the language setting changes, is there any way to implement this as the normal .resx files ? 
    as for normal .resx  files I can do this 
    

((ResourceWrapper)Application.Current.Resources["ResourceWrapper"]).ScreensRes = new ScreensRes();

    after changing the culture .

Best regards
