Programmatically Invoking Mvc Controller Action From Webforms Page?
Sep 15, 2010
Is it possible to invoke an action on asp.net mvc controller programmatically from a classic webforms page that is not handled by MVC but running in the same web application?
We have a mixed asp.net web application: webforms for page rendering and mvc for ajax calls. But we want to render some MVC views from webform page on the server via the code (not a web request)...
Currently we are doing a web request locally to get the rendered view: is it the right/only way?

I have an MVC 1.0 app that makes several AJAX calls from JS files. Originally I was just specifying the relative URL like so:
[Code]....
This works but it feels rather like a hack. Is there any way to do what Url.Action does but in the JS code itself? I've had a bit of a search but I'm having trouble coming up with the correct keywords, or else the info just isn't out there.

I have a controller's action and view page that uses a master page.
The master page has the html title section like:
<title>this is the page's title</html>
How can I access this section from within my controller's action (preferably) or my action's view page?

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 am quite new to MVC development and facing some basic issues.
I am having a form on which I am taking input form user. It is bould to one of the properties on Model class.
I am having a submit button
<input type="submit" value="Save"/>
Now I want to call Save Action in my controller on click on this Save button.
But it is not working. I have checked on following things:
1. My HTML page is correctly point to the controller
2. I have written HTML code as
<%= HTML.BeginForm("Save","ControllerName", FormMethod.Post); %>
<input type="submit" value="Save"/>
<%= HTML.EndForm();%>

I think normally the execution sequence is content page's controller first, then master page (I have some inline code).
But now I have a situation that master page's inline code is executed before content page's controller.

I'd like to invoke a button click event on an ASP.net page programmatically, using c#. I don't have access to the server-side of the page, so i can't invoke the function directly.

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?

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 tried doing so
[Code]....

I have an odd problem. I have a page called search.aspx. When the search button is clicked, the user is supposed to be redirected to another website. The redirection code is in one of the postback events.
Here is the form code:
<form id="form1" runat="server" onsubmit="return CheckSearchBox();" action="http://mysearch.company.com/default.aspx" method="post" target="_top" >
I have this same code deployed in two environments. Working Environment It has .NET 2.0 and 3.0, but no service packs. Here is how the source is rendered:
<form name="form1" method="post" action="search.aspx" id="form1" onsubmit="return CheckSearchBox();" target="_top">
Broken Environment
It has .NET 2.0 sp2 and 3.0 sp1.
This is how the same code is rendered:
<form name="form1" method="post" action="http://mysearch.company.com/default.aspx" id="form1" onsubmit="return CheckSearchBox();" target="_top">
Notice that the rendered "action" is different. So, I have a few questions.
Why would ASP.NET change the action in one situation, but not the other?
Why would ASP.NET change the action at all?
Is there some sort of configuration I can make so that it always changes the action to "search.aspx"? (We haven't changed this code in years, and nobody wants to touch it.)

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

My way to ASP.NET MVC was not across ASP.NET Web Forms, so it's hard for me to understand how better to pass value from ASP.NET MVC controller to ASP.NET webforms script which is inside MVC View.
For example, controller action:
[Code]....
How to assign a value of myvar from a controller action to par1 variable in the View instead "stubvalue"?

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.

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.
.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")
}))

A well-known benefit of MVC is its suitablility for Test Driven Development (TDD) because you can directly call your controller actions from your test methods.
How can you test the combination of a controller action with a ActionFilter attribute (using OnActionExecuted to modify the ActionResult returned by the Action)? If I just call the Action, it returns the ActionResult from the action, but the filter attribute is never invoked. I think maybe you can get it by Controller.ActionInvoker.InvokeAction(controllerContext, "ActionName"), but you have to accurately mock so much of the controllerContext to make it work that it's a real pain.
