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?
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); }
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?
So I have a dropdown in a form which when at item is selected postback to database and get some values which I am now storing in an object. I need to get the values from this object into textboxes on the form in the view..how can I do this???
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 have asp.net mvc application. i want to configure the object in jquery and want to pass it to the the action of controller . where as in my script i am using this for configure data for the ajax call:
[Code]....
it does not calls to action in controller. i think here :
var json = $.toJSON(peform);
is not working as expect. is it need to add any js file to reference ? or mistake in syntax?
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:
[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.
When I use editurl property in my jqgrid, the controller action gets called after I hit submit button on adding a new row. But how do I get all the grid rows there? Which parameter should I read from my controller action method in order to get the grid data?
I have a User entity and a department entity. I have a UserViewModel and DepartmentListModel which has List of departments.
UserViewModel has a property of type DepartmentListModel .
Now on user/create action I need to populate DepartmentListModel by calling DepartmentController's list action. List action returns populated DepartmentListViewModel.
From UserController how do I set DepartmentListModel ?
I have one controller with 4 to 5 action method. In all action method i have to check some feilds from database. So to reduce the database query i want to save this data one time and then want to use that in all action method. I know about tempdata and view bag but none of this can use in different action method, so how to achive this.
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.
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 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.
In ASP.NET MVC 2, to secure controller action, i have created a class RequirePermission inherited from ActionFilterAttribute class. The controller action looks like
[Code]....
Now instead of making different attributes , I want to use RequirePermission attribute like [RequirePermission(permissions=Permissions.CanView+","+Permissions.CanEdit)] so that i can use it for different scenerious. but the compiler throw the following error. An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type
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.

I could do something like this, but its dirty ... well it leaves me with that dirty feeling.
I would like all actions of a controller to read some master page level values from the querystring and write those values to ViewState. How do I do this in ASP.NET MVC?
What's the correct way to get the controller name and action from an httpContext object? I can see the values in the debug, but I don't seem to be able to get to them in the object code?
I have a user control in a modal popup for login form. It's ajax post so when login is successfull it doesn't update the rest of the page. Would like to just redirect the user to thier current page but not 100% on how to do this from the accountController.
