• Re: TryUpdateModel gives System.MissingMethodException: No parameterless constructor defined for this object.

  In some places I could see that, but in most of those situations those properties aren't public anyway. I generally don't make a domain object's property public unless i'm already going to allow it to be set from the UI. But that makes me wonder, what if you have a public get, but a private or protected set? Would UpdateModel() set that anyhow? Craig

• Re: TryUpdateModel gives System.MissingMethodException: No parameterless constructor defined for this object.

  Cool thanks. THat was my suspicion, because when I removed a property to another class that had lots of deep references to other objects, then the problem went away. When I put that property back, the error resurfaced. I can just explicitly state my properties for now and its happy. Glad you guys are on top of it and I'm really pleased w/ MVC so far. It is probably one of the biggest improvements to ASP since .NET.

• Re: TryUpdateModel gives System.MissingMethodException: No parameterless constructor defined for this object.

  Well, I changed my code to do this: this.UpdateModel(purchase, "purchase", new[]{ "Comments", "TypeOfPayment", "PurchaseTime" }); and explictly stated my properties to update, and all was well, but i suspect this is a bug in asp.net MVC. I think somewhere in my hiearchy of objects I had a reference to an object that did not have a parameterless constructor, so thats why it failed. Please fix this if you can replicate it somehow!

• Re: TryUpdateModel gives System.MissingMethodException: No parameterless constructor defined for this object.

  The odd thing is, this only happens during Unit Testing, not when running the page. I'm using structure map and NUnit to do my testing and DI.

• TryUpdateModel gives System.MissingMethodException: No parameterless constructor defined for this object.

  I keep getting this error with this code in my controller: var purchase = new PurchaseInquiry(profile, product); this.TryUpdateModel(purchase, "purchase"); Why does MVC need a parameterless constructor on my object when I'm doing the constructor for it? I dislike having the presentation layer dicate how my domain objects look. craig

• Re: Are we going to see MVC controls?

  You know I thought lack of controls would be a show stopper, but its really not. The extra abstraction layer that webforms provided also created a lot of problems (viewstate, styling, javascript integration because of renamed ID attributes, lifecycle issues, etc) So instead of using any server controls we've adopted JQuery.UI as our control replacement. For basic stuff like textboxes and things we use Html helpers but for the really heavy UI stuff, we use something that is designed for it. Keeping

• Logic (not presentation) shared between controllers

  I am in a situation where I need to reuse some logic in one controller in another. The views/presentation is different. Basically, I have two different ways of registering. The user can click at the top of the page on a "register" link and fill out the normal info: name, email, address, password, etc. Or, they can register as they are requesting more information about a product. They see the information about the product, as well as the normal registration fields above and a few new fields

• Re: RenderAction

  that doesn't see all that different from what we're doing, except that by having the call to the other controller as an attribute, you wouldn't be able to decide whether to call it or not at runtime. But seems like this could be done similarily thru C# code. Something like: public ActionResult Foo() { var results = InnerController.Bar(); this.ViewData["barResults"] = results.Html; } <% Html.RenderSubView( this.ViewData["BarResults"] ) %>

• RenderAction

  This is probably more of a discussion then a simple question, but i'm curious why some people are against putting "Html.RenderAction()" to reuse controller methods? I guess because the view is calling the controller? What would be an alternative to this to still allow controller methods and their views to be reused (like controls) ? Thanks, Craig

• Partial page caching

  I'm using preview 5 and trying to get some partial page caching. I don't want to use a user control. I am instead using RenderAction() to render one of my controllers. Then I'm putting [OutputCache(Duration=1200)] on my controller method, but its still firing every time and not caching when called in this way. Is this not supported yet? Is there another way i should be doing this? Thanks, Craig
