I have tried to use default parameters, regex, and nothing works for the URL "/Assets/Images/". I keep getting a 404 error saying it cant be found. It works with just "/Assets/Images/0".
routes.Add(
"Images",
new Route(
"Assets/Images/{*Id}",
new ImageRouteHandler(new ImageHandler())
)
);
You need to add an action to AssetsController called Images
public class AssetsController : Controller
{
public ActionResult Images()
{
return View();
}
[HttpGet]
public ActionResult Images(int id)
{
return View();
}
}

I am creating an MVC 5 application. I am using Rotativa to generate PDFs
they have a method called
public ActionAsPdf(string action, object routeValues);
I am having trouble to direct to POST method of an action
this is that GET and POST actions
[HttpGet]
[ValidateInput(false)]
public ActionResult Create_Brochure(IEnumerable<ProductsPropertiesVM> model)
{
.............
return View(selectedIDs);
}
[HttpPost]
[ValidateInput(false)]
public ActionResult Create_Brochure(string m)
{
return View();
}
Once I run this program its directing to GET method but I want to direct to POST action
using following method
public ActionResult PrintIndex()
{
return new ActionAsPdf("Create_Brochure") { FileName = "Test.pdf" };
}
You need to match the parameters of the POST version of Create_Brochure:
return new ActionAsPdf("Create_Brochure", new List<ProductsPropertiesVM>())
{
FileName = "Test.pdf"
};
Of course, you'll have to pass the correct model data instead of the List<ProductsPropertiesVM>.
I can change the method name but can anyone tell me why this doesn't work? How can i make it working without changing method name. Also I don't want to specify the action name in the view. Is it possible?
[HttpGet]
[Route("AddUpdateCategories/{storeId}")]
public ActionResult AddUpdateStoreCategories(int storeId)
{
return View();
}
[HttpPost]
public ActionResult AddUpdateStoreCategories(int StoreId,int[] ShopCategoryId)
{
return null;
}
Problem is post action is not getting called on submit.
You don't have to change the method name. The problem is that this post action has no route. If you use attribute routing, you have to specify a route for each action. Both of these actions would end up with the same route attribute, but the [HttpPost] attribute is enough for the routing framework to work out which one to use.
[Route("AddUpdateCategories/{storeId}")]
public ActionResult AddUpdateStoreCategories(int storeId)
{
return View();
}
[HttpPost]
[Route("AddUpdateCategories/{storeId}")]
public ActionResult AddUpdateStoreCategories(int StoreId,int[] ShopCategoryId)
{
return null;
}
I am trying to redirect to action and get a new view (a new page) with no success. While debugging, I'm reaching the controller but not getting the view (the page URL is not changed).
With Fiddler I see that the page returns the right view result but in the browser the URL is not changed!
When shopping cart is empty, I would like to redirect to a new page a display the error message.
[HttpPost]
public RedirectToRouteResult PlaceOrder(DeliveryDetails deliveryDetails)
{
if (UserCart.IsEmpty)
{
TempData["errorMsg"] = "Error: Cart is empty";
return RedirectToAction("Index", "Error");
}
else
{
InsertOrder();
}
}
ErrorController:
public ActionResult Index()
{
return View();
}
ErrorController View:
#TempData["errorMsg"]
Thanks.
Then I would surmise that UserCart.IsEmpty is evaluating to false. What does your Error Index route look like? Also, you're better off returning a base ActionResult from a controller action in case you need to return a view. Presumably there's more code in the PlaceOrder method because that won't compile as it stands
Use ActionResult instead of RedirectToRouteResult
[HttpPost]
public ActionResult PlaceOrder(DeliveryDetails deliveryDetails)
{
// .....
return RedirectToAction("Index", "Error");
}
On a MVC controller I have the following:
public virtual ActionResult Test() {
ActionResult result = MVC.Home.Index();
return RedirectToAction(result);
return View();
}
This redirects to result. View is never returned.
Now I need to do something as follows:
public virtual ActionResult Test() {
ActionResult result = MVC.Home.Index();
MyClass.RedirectTo(result, this);
return View();
}
Where MyClass.RedirectTo method is the following:
public static void RedirectTo(ActionResult result, Controller controller) {
controller.Response.Redirect(result.ToString());
}
But in this case the redirection does not happen.
The View is returned. Does anyone knows how to do this?
Hi you have to redirect to a specific action on a specific controller
e.g
return RedirectToAction("Index", "ControllerName");
I have this set of routes:
routes.MapRoute(
"IssueType",
"issue/{type}",
new { controller = "Issue", action = "Index" }
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
Here is the controller class:
public class IssueController : Controller
{
public ActionResult Index()
{
// todo: redirect to concrete type
return View();
}
public ActionResult Index(string type)
{
return View();
}
}
why, when i request http://host/issue i get The current request for action 'Index' on controller type 'IssueController' is ambiguous between the following action methods:
I expect that first one method should act when there is no parameters, and second one when some parameter specified.
where did i made mistake?
UPD: possible duplicate: Can you overload controller methods in ASP.NET MVC?
UPD 2: due to the link above - there is no any legal way to make action overloading, is it?
UPD 3: Action methods cannot be overloaded based on parameters (c) http://msdn.microsoft.com/en-us/library/system.web.mvc.controller%28VS.100%29.aspx
I would have one Index method that looks for a valid type variable
public class IssueController : Controller
{
public ActionResult Index(string type)
{
if(string.isNullOrEmpty(type)){
return View("viewWithOutType");}
else{
return View("viewWithType");}
}
}
EDIT:
How about creating a custom attribute that looks for a specific request value as in this post StackOverflow
[RequireRequestValue("someInt")]
public ActionResult MyMethod(int someInt) { /* ... */ }
[RequireRequestValue("someString")]
public ActionResult MyMethod(string someString) { /* ... */ }
public class RequireRequestValueAttribute : ActionMethodSelectorAttribute {
public RequireRequestValueAttribute(string valueName) {
ValueName = valueName;
}
public override bool IsValidForRequest(ControllerContext controllerContext, MethodInfo methodInfo) {
return (controllerContext.HttpContext.Request[ValueName] != null);
}
public string ValueName { get; private set; }
}
I ran into a similar situation where I wanted my "Index" action to handle the rendering if I had an ID specified or not. The solution I came upon was to make the ID parameter to the Index method optional.
For example, I originally tried having both:
public ViewResult Index()
{
//...
}
// AND
public ViewResult Index(int entryId)
{
//...
}
and I just combined them and changed it to:
public ViewResult Index(int entryId = 0)
{
//...
}
You can do it using an ActionFilterAttribute that checks the parameters using reflection (I tried it) but it's a bad idea. Each distinct action should have its own name.
Why not just call your two methods "Index" and "Single", say, and live with the limitation on naming?
Unlike methods that are bound at compile time based on matching signatures, a missing route value at the end is treated like a null.
If you want the [hack] ActionFilterAttribute that matches parameters let me know and I'll post a link to it, but like I said, it's a bad idea.
All you have to do is mark your second Action with [HttpPost]. For instance:
public class IssueController : Controller
{
public ActionResult Index()
{
// todo: redirect to concrete type
return View();
}
[HttpPost]
public ActionResult Index(string type)
{
return View();
}
}
