How to set properties in a custom WebViewPage?

问题

I have a very basic custom WebViewPage class in which I want to assign a value to a custom property. Here's my code:

public abstract class WebViewPage :
    System.Web.Mvc.WebViewPage {
    public Employee UserPrincipal { get; set; }

    public override void Execute() {
        // Controller is also a custom class that contains the same property which is injected by
        // a custom ActionFilterAttribute. I've confirmed that the attribute is correctly updating
        // the property.
        Controller controller = (this.ViewContext.Controller as Controller);

        if (controller != null) {
            this.UserPrincipal = controller.UserPrincipal;
        }
    }
}

    <pages pageBaseType="X.Mvc.WebViewPage">
        <!--System.Web.Mvc.WebViewPage-->

From what I can tell the Execute method is not being called for some reason because I never hit any of the breakpoints I put in it. I have properly updated the Web.config to point to my custom WebViewPage and I can access the property from within the view, I just can't seem to set the property correctly.

I'd appreciate it if someone could point me in the right direction.

回答1:

Well, I don't know why Execute isn't being called, but InitializePage is, so I overrode it instead. This works:

public abstract class WebViewPage :
    System.Web.Mvc.WebViewPage {
    public Employee UserPrincipal { get; set; }

    protected override void InitializePage() {
        base.InitializePage();

        Controller controller = (this.ViewContext.Controller as Controller);

        if (controller != null) {
            this.UserPrincipal = controller.UserPrincipal;
        }
    }
}
