To Return The Same Data For Every .Net MVC Action In A Particular Controller?
Mar 26, 2011
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?

How does a controller action return an HTML stream as the View? ( in place of the name of the View file )
I want to return a simple "error detected" or "action completed" page to the browser. And I dont want to clutter up my project with yet another view. The return string being "<html><body><h1>Error. Customer xxxx is not found</h1></body></html>"
( thinking about it, better to have a general purpose view in a folder named "Common". Then pass the message text in ViewData. Still curious to know how to return an html stream. )

Lets say I have a simple controller for ASP.NET MVC I want to test. I want to test that a controller action (Foo, in this case) simply returns a link to another action (Bar, in this case).How would you test TestController.Foo? (either the first or second link)
My implementation has the same link twice. One passes the url throw ViewData[]. This seems more testable to me, as I can check the ViewData collection returned from Foo(). Even this way though, I don't know how to validate the url itself without making dependencies on routing.The controller:
public class TestController : Controller
{
public ActionResult Foo()[code].....

I'm trying to add file upload functionality to a page. I've got a form that posts the selected file to a controller with a 'savefile' method. But if I don't add a get version of 'savefile' I'll get a 404 error. Here is the form code which is presented on the Index page:
[Code]....
And here is the controller code:
[Code]....
Intuitively I don't think I should need a GET version of SaveFile but if omit it I get a 404 error when the form posts. Why should I need a GET version of SaveFile when all I want is to post a form and save the file?

Basically, I have an HTML Form and would want to pass the data from the form to n asp.net mvc controller, then the controller would return an XML for client side manipulation.
Here is my initial code:

When I run and debug, I get a message that says "attr(..) is null or not an object. I am still trying to learn web development using ASP.NET MVC.

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.

I have an edit application view, and it can be found at the following URL:
http://localhost:17262/Application/EditApplication/1
1 equals the application ID.
Also on the page I have a link that goes to another view to add an assistant for the application. I want to pass it the application ID so that the new assistant can be "linked" to this application. How would I get the value of 1 and add it to my action link? This is what I have in my HTML so far:
<%: Html.ActionLink("Add New Assistant", "Create", "Assistant", new { applicationID = "id" }, null) %>

If I have a controller with more than one action on, e.g. UserController, then I end up having that class require every dependency of every action. Is there a way I can have one controller per action and yet have the URLs appear the same way they currently do? e.g.MySite.com/User/Edit/1 would remap to User_EditController.Edit

I am not sure what is going on but even though I am invoking a different controller with action a particular FooController's Index action is being invoked all the time. The Global.asax file has setup the FooController to be the default controller.
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "FooController", action = "SomeAction", id = UrlParameter.Optional } // Parameter defaults
);
}

I have an aspx page Test.aspx. It handles requests like
Test.aspx?First=value1&Second=value2&third=value3
How can I use routing to redirect this url to
TestController/MyAction?First=value1&Second=value2&third=value3
I know I can create an aspx and perform redirect in it`s page load. But seems ugly and I think it can be done with some custom route.What I`ve tried was: this solution.but it didnt work for me. I remember, that Test.aspx should not be on a disk. I don`t have it, and routing is still not working.

I know I can use Html.ActionLink(...) from my view to render an anchor tag with a link to an action. I know I can call RedirectToAction(...) from the controller to immediately call another action. But what I'd like to do (and don't know how), is get an action link from within the controller. I am building up a breadcrumb and want the link to an action. So I don't want to immediately jump to the action (as with RedirectToAction), but just get what the link would be.

I am calling a Controller Action from a view, within that controller I need to invoke another Action which I will invoke to save the view to a network location as either HTML or Image.
How do I retrieve the URL to an Action from within a Controller. I need the actual URL, this means RedirectionToAction or View() wont work.
Why? I need to pass in a URL which will contain a call to a View. This view will be used to generate an image or HTML document using the System.Windows.Forms.WebBrowser.
.NET 3.5; C#; MVC 1;
I could do something like this, but its dirty ... well it leaves me with that dirty feeling.
using(Html.BeginForm("Action", "MyWorkflowController",
new {
MyId = "bla",
URLToGenerateImage = Url.Action("GenerateImage", "MyWorkflowController")
}))
