@{ ViewBag.Title = "About Us"; } @using (Html.BeginForm(new RouteValueDictionary { {"Action","Index"}})) { <input type="submit" value="submit"/> } When I render <form action="/Home/Index" method="post"><input type="submit" value="submit"/> Is this the actual use of RouteValueDictonary.

阅读更多关于 JSON Date parameter passed to MVC Action is always null

I have a range of parameters that are passed via jQuery Ajax to an MVC JsonResult action. For the most part, these arrive successfully, but there is a Date value that is not arriving at all. What considerations / formats do I need to use - or what approaches do I need to take - in order to get this date to arrive successfully? ...other code ... myStory.Deadline = new Date($('#story-deadline').val()); $.ajax({ url: '/Project/' + action[2] + '/AddStory', data: { Summary: myStory.Summary, Size: myStory.Size, Priority: myStory.Priority, Owner: myStory.Owner, Deadline: myStory.Deadline }, dataType:

In ASP MVC, how can I return a new view AND a file to the user?

阅读更多关于 In ASP MVC, how can I return a new view AND a file to the user?

Thought I would pose this to the StackOverflow crowd since I've run out of ideas. I have a request from users that once a button is clicked, a PDF form is generated which they would like to automatically view, and once they close the PDF the page will already be a "Final page", not the page they clicked the button from. In my pre-final page with the button, the controller calls: return File(finalForm, "application/pdf", Server.HtmlEncode(finalForm)); But this has now passed the control to the client, I can't route to a different View. Any clever ideas on how I can also display a new view? I've

How to remove flashing on persisting remotely populated jqgrid tree node

阅读更多关于 How to remove flashing on persisting remotely populated jqgrid tree node

jqGrid tree nodes are read from server using json data. Click in node reads child nodes from server. Code below is used to restore opened tree node if page is loaded. Only single node is opened always in tree. Controller assings node ids to autoClicked array and gridComplete opens nodes using this path. This causes grid flasinging on page load since multiple server requests buid grid multiple times. How to disable grid flashing ? Is it possible to prevent multiple jqGrid building and show only find jqGrid tree ? Answer in Send expanded TreeGrid Nodes in cookie works for fully populated grid

问题 I just downloaded VS.NET 2010 RC and created a new MVC project. It would seem that strongly typed ActionLinks are not in this release? Is this always going to be a "futures" thing?
