Passing initParam from ASP.NET ?

Jan 8, 2009 at 6:24 PM
Hello, i am trying to pass parameters to an SL app embedded in a Asp.Net page, which is typically done this way

 private void Application_Startup(object sender, StartupEventArgs e)
            // Get the schedule id
            Bootstrapper bootstrapper = new Bootstrapper();
            bootstrapper.InitParams = e.InitParams;

however i would like to pass this parameters to a specific module, loaded by the bootstrapper from a module catalog.

How can i initialize the module a parameter ?

Thank you,

You can use the container within the Bootstrapper as follows:


public class Bootstrapper : UnityBootstrapper


    public IDictionary<string,string> InitParams { get; set; }


    /// <summary>

    /// Creates the shell.

    /// </summary>

    /// <returns></returns>

    protected override DependencyObject CreateShell()


              ("InitParams", InitParams);

        Shell shell = Container.Resolve<Shell>();



        Application.Current.RootVisual = shell;




        return shell;



public class EmployeeModule : IModule


    private readonly IUnityContainer container;

    private readonly IRegionManager regionManager;


    private IDictionary<string, string> initParams;


    /// <summary>

    /// Initializes a new instance of the class.

    /// </summary>

    /// <param name="container">The container.</param>

    /// <param name="regionManager">The region manager.</param>

    public EmployeeModule(

        IUnityContainer container,

        IRegionManager regionManager)


        this.container = container;

        this.regionManager = regionManager;


        this.initParams =

            container.Resolve<IDictionary<string, string>>

Thanks for the prompt answer Bill,

if i understood it, this is the procedure to give global access to any object, right ? Registering it the container.

Container.RegisterInstance<IDictionary<string,string>> ("InitParams", InitParams);

this.initParams = container.Resolve<IDictionary<string, string>>("InitParams");

Correct, any registered instances will be available to resolved classes.

I can't register instance like below

              ("InitParams", InitParams);


because Container seems to be read only property.
