I am fairly new to MVC and just trying to achieve something which I think shouldn't be too complicated to achieve. Just want to know what the best approach for that is. I have an Event-RSVP application (NerdDinner kind) where you go to view details of the event and then click on an AJAX link that will RSVP you for the event.
<%
if (Model.HasRSVP(Context.User.Identity.Name))
{
%>
<p>
You are registered for this event!
<%:
Ajax.ActionLink("Click here if you can't make it!", "CancelRegistration", "RSVP", new { id = Model.RSVPs.FirstOrDefault(r => r.AttendeeName.ToLower() == User.Identity.Name.ToLower()).RSVPID }, new AjaxOptions { UpdateTargetId = "QuickRegister"})
%>
</p>
<%
}
else
{
%>
<p>................
My ascx is pretty big & I'd like to reuse it, changing controller/method in Html.ActionLink with another controller/method. Method of another controller has the same signature as PersonController.Publications. Whats best way how to make controller/method configurable for my layout.
display the first tier of data so the user can select and tweak desired rows. On occasion, they will want to drill into a row to see the children and select/tweak them. After a tweaking session, I wanted to be able to commit.
If I build an aggregate ViewData and prepopulate it, I can display it just fine in the View, and I get the collection back in the postback just fine.
Starting with empty child data, I experimented with jscript to fetch that data and displayed it by adding elements with jquery.
What I can't figure out how to do is to return that data to the controller. The newly added elements aren't in "Show Source" ... I heard elements added via jscript are not posted back. I even tried adding items to a prepopulated list ... only those items originally passed in are returned.
my MVC2 delete and only my delete controller is refusing to return any class information. Its really similar to my edit function and the views are all auto-generated so I don't see the problem.
Function Delete(ByVal id As Integer) As ActionResult

I am new to MVC2 and have hit a wall. When I use an action link to jump back to a previous page that I have already been on, my controller is not called but the page is rendered correctly. Is this some sort of caching that I am not aware of? This also happens with a RedirectToAction call from another Controller. rfm is the Model...

I have a problem trying to retrieve a return value from a javascript function and using it from my code behind. The problem is after I call my UpdatePanel.Update() method and call return, I can't continue as I have ended execution of the page by calling return. Please find an example of my code: [Code]....
I have .aspx page methods with return type of string, which work great. I am using some jQuery ajax, and some .NET Ajax "PageMethods.methodName" syntax from the client side to successfully call these page methods. I need to return xml from a page method.... I would LOVE to be able to return system.Xml.Linq.XElement type from page method. I get a serialization circular reference error when I attempt to return XElement or XDocument. I don't really want to return XML.ToString() to client, and then convert string to xml in javascript. What return page method return type(s) would allow me to retrieve xml with jQuery ajax call? I know json is the alternative, but will not give me what I need this time.
I've a method associated with an actionlink in the asp.net mvc view. When user clicks on actionlink the method is being called twice before the user is redirected to an appropriate page. Following is the code.
If I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.
If I have a controller and I want to return a view based on what my conditional logic goes to, is that possible? I have different types of models that i want to insert into a view DEPENDING on my conditional logic (if statements) Can i do this? and how would I do this
I have a controller with several actions that all return a set of data that's the same among them all. Instead of adding the data to the ViewBag in every single action, is there some pattern or attribute or something I can call or set to add the same data to the viewdata or viewbag for every action, or some other better way to perform the get the same data in every view without calling the method in every action?
i am trying return a double value from controller action. when i alert(result) it works well but when i return a function it did not work. alert undefined value.
//this is action public ActionResult GetPrice(int id) { double price = ProductList.Where(d => d.ID.Equals(id)).Single().Price; return Json(price, JsonRequestBehavior.AllowGet); }
I have a list of items(surveys) displayed on my home page. When I click the edit button for a particular item I have a modal pop up with the items details to edit. When the user clicks Save I submit the form via ajax. Depending on whether ModelState.IsValid == true I want to update the modal with validation information or close the modal and update the list of items with the new information.
This is how I am submitting the form:
[Code]...
My Questions
The only thing I can think to do is return JSON from my controller with a flag indicating the state of the ModelState.IsValid and the corresponding partial that I should show.
1) How would I do this?
2) Is there a better way?
Update
I found this: [URL]
but it seems more likely that I am going about the whole thing incorrectly.
I have an application that has an public 'end user' mode and a 'back office' mode. Both 'modes' pretty much share the same controller logic but the user interfaces for these different 'modes' are radically different. Using the out of box default routing that you get when a project is created for the first time I have something like the following:
Controllers HomeController.cs Views BackOffice Index.aspx Public Index.aspx Shared BackOfficeSite.Master PublicSite.Master In my HomeController.cs I have logic that looks like this: public ActionResult Index() { var devices = DeviceRepository.FindDevicesByCustomer(100); if(IsBackOffice()) { return View(@"~/Views/BackOffice/Index.aspx", devices); } return View(@"~/Views/Public/Index.aspx", devices); }
Is this the correct way to be doing this or am I digging myself an anti-pattern hole? I'm using ASP.NET MVC 2.
