viewbag

I am reading a book on ASP.NET MVC and I'm wondering how the following example works: Example #1 Controller public class MyController : Controller { public ActionResult Index() { ViewBag.MyProperty = 5; return View(); } } View <h1>@ViewBag.MyProperty</h1> Now I understand that ViewBag is a dynamic object, so that's how you can set the property (though I don't know much about dynamic objects, never worked with them.) But how does the view get the specific instance of the ViewBag from the controller, even though we don't pass anything directly? I thought that the ViewBag could be a public static

I have a situation where I would like to do something simular to what was done with the ASP.NET MVC 3 ViewBag object where properties are created at runtime? Or is it at compile time? Anyway I was wondering how to go about creating an object with this behaviour? Use an object of type dynamic . See this article for more information. I created something like this: public class MyBag : DynamicObject { private readonly Dictionary<string, dynamic> _properties = new Dictionary<string, dynamic>( StringComparer.InvariantCultureIgnoreCase ); public override bool TryGetMember( GetMemberBinder binder,

This seems so simple it's embarrassing. However, the first question is when passing a value from the new ViewBag in MVC 3.0 (Razor) into a JavaScript block, is this the correct way to do it? And more importantly, where and how do you apply the proper string replacement code to prevent a single quote from becoming &#39 as in the resultant alert below? Adding this into a single script block: alert('@ViewBag.str') // "Hi, how's it going?" Results in the following alert: Razor will HTML encode everything, so to prevent the ' from being encoded to ' , you can use alert('@Html.Raw(ViewBag.str)');

I have an action filter that is responsible for placing some common information into the ViewBag for use by all views in the shared _Layout.cshtml file. public class ProductInfoFilterAttribute : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { // build product info // ... (code omitted) dynamic viewBag = filterContext.Controller.ViewBag; viewBag.ProductInfo = info; } } In the shared _Layout.cshtml file, I use the information that has been put into the ViewBag. ... @ViewBag.ProductInfo.Name ... If an exception occurs while processing a

By default the new project template for ASP.NET MVC 3 adds the following to the default layout (masterpage in razor): <title>@ViewBag.Title</title> The view must then contain the following to assign the title of the page, for instance: @{ ViewBag.Title = "Log On"; } Perhaps it is just my own preference but I find that using the ViewBag to hold the title a little bit wrong (I'm thinking too much magic-string flavor). So my question is: Is this the recommended best practice for people using ASP.NET MVC 3 and razor (using a dynamic property bag) or are you opting for something more strongly typed
