Say you create a form using ASP.NET MVC that has a dynamic number of form elements. For instance, you need a checkbox for each product, and the number of products changes day by day. How would you handle that form data being posted back to the controller? You can't set up parameters on the action method because you don't know how many ...
This may not be the correct way to use controllers, but I did notice this problem and hadn't figured out a way to correct it. public JsonResult SomeControllerAction() { //The current method has the HttpContext just fine bool currentIsNotNull = (this.HttpContext == null); //which is false //creating a new instance of a...
Hi, I have an ASP.NET MVC view which contains checkboxes for user-defined categories. <td><% foreach (Category c in (List<Category>)ViewData["cats"]) { if (selCats.ContainsKey(c.ID)) { %> <input name="CategoryIDs" type="checkbox" value="<%=c.ID %>" checked="checked" /> <%= c.Name%><% } else { %> <inpu...
I've just started working with ASP.NET MVC now that it's in beta. In my code, I'm running a simple LINQ to SQL query to get a list of results and passing that to my view. This sort of thing: var ords = from o in db.Orders where o.OrderDate == DateTime.Today select o; return View(ords); However, in my View, I rea...
I am very impressed with the ASP.NET MVC stuff--and I've seen the various blogs and am quite anxious to dig in. But where are the docs? I can't find any docs on the System.Web.Mvc namespace, or any of its related namespaces. Google searches limited to msdn.microsoft.com don't turn up anything, nor does just googling. I know there are a...
On an ASP.NET MVC (Beta) site that I am developing sometimes calls to ActionLink will return to me URLs containing querying strings. I have isolated the circumstances that produce this behavior, but I still do not understand why, instead of producing a clean URL, it decides to using a query string parameter. I know that functionally they...

I want to dynamically add menuitems to my master page based on membership security login role. From what I've read RenderAction in the master page html could perhaps do this. Since I'm fumbling thru this I am not sure how it would look and how in the controller I check my current role. I am considering creating a table and relating the a...
