In my application I have a string parameter called "shop" that is required in all controllers, but it needs to be transformed using code like this:
shop = shop.Replace("-", " ").ToLower();
How can I do this globally for all controllers without repeating this line in over and over?
I have a simple model where a Person has Gifts. I have a view which is a list of Gifts belonging to one Person.
My problem is with the Create action for a new Gift. I want it to default to the PersonID that we are already viewing the list of Gifts for. I tried simply passing the last PersonID (they are all the same)
Html.ActionLink("Create New", "Create", new { id = Model.Last().PersonID }) which works fine if there is already at least one Gift for that person but if this is the first Gift I don't have a value.
My Gift List controller knows the PersonID I want to pass but the view doesn't.
How do I pass this PersonID from my Gift List controller to my Gift Create controller via the Gift List view? Or is there a better way to do this?
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?
View 1 RepliesI have the following scenario: my website displays articles (inputted by an admin. like a blog).So to view an article, the user is referred to Home/Articles/{article ID}.However, the user selects which article to view from within the Articles.aspx view itself, using a jsTree list.So I what I need to do is to be able to differentiate between two cases: the user is accessing a specific article, or he is simply trying to access the "main" articles page. I tried setting the "Articles" controller parameter as optional (int? id), but then I am having problems "using" the id value inside the controller.

My method looks like:
public static RedirectToResult(Controller controller, ...)

I get RedirectToAction from within the controller's action, but not when I pass the controller as a parameter to another classes method.
I'm using a custom route to create the following URL (http://mysite/subscriber/12345) where 12345 is the subscriber number. I want it to run the ShowAll action in the Subscriber controller. My route is firing and using Phil's route debugger, when I pass in the above url, the route debugger shows ID as 12345.
My controller is accepting an int as subscriberID. When it fires, the controller throws the error "The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32". Why does the route debugger show a value and the controller doesn't see it?
Here's my route (first one is the culprit)
routes.MapRoute(
"SubscriberAll",
"subscriber/{id}",
new { controller = "Subscriber", action = "ShowAll", id=0 },
new { id = @"d+" } //confirm numeric
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
I'm getting a null in the ShowAll action? Here is the action method signature:
public ActionResult ShowAll(int id)

so in this line i am passing "ss".but in my controller i didnot get the value in a parameter variable, instead i am getting ss as parameter, not the selected ids.how can i do that.
I have a requirement whereby I need to be able to change the controller being used based upon a parameter. I am creating an application that needs to be dynamic enough to be able to change controllers on the fly. Let me explain further;
When the application starts a dictionary of custom controller names is loaded with a controller name as the key and a custom controller name as the value. This will be help in the application scope.
When a request is made I need to access the requested controller name, use that name and check to see if it matches a key in my controller dictionary and if so, replace the requested controller name with the custom controller name from the dictionary.
example;
My dictionary will contain data as follows
Key: 'Home', Value: 'Home_IN'
Key: 'Customer', Value: 'Customer_BE'
Now, the following request is made 'User/Edit/1'. Does the controller name exist in the dictionary? No, continue with original request.
Now, the following request is made 'Home/Details/2'. Does the controller name exist in the dictionary? Yes, replace the original controller name 'Home' withe custom controller name 'Home_IN' so changing the requested URL to be 'Home_IN/Details/2'.
Does this make sense?
My problem here is knowing exactly where in the request cycle I need to do this?
I am assuming I need to create my own custom controller factory?
m having problem in passing parameter to controller action, i have done the following

We are in the process of building a huge site. We are contemplating on whether to do the processing of HTML at server side (ASP .Net) or at the client side. For example we have HTML files which acts like templates for the generation of tabs. Is it better for the server side to get hold of content section (div) of HTML load the appropriate values and send the updated HTML to the browser or is it better that a chunk of data is passed onto client and make Javascript do the work?
View 2 RepliesUML and Patterns: An Introduction to Object-Oriented Analysis and Design and Iterative Development, that follows the UP(Unified Process). It uses a Grasp Controller pattern to interact with domain classes by some methods like NewSale(), AddNewItemToSale() and CloseSale. In windows form, I can instantiate a object of this class in the UI and then use its methods to perform the actions. This works well in Client apps, but when I use asp.net mvc, I cannot find a way to instantiate an object (one for each user) that was always visible for a Controller (MVC). I cannot insert as an attribute inside Controller because it always create a new one.

I have a filter on my MVC web site. I display some records in a few different controller actions but when moving from one action to another I want to apply those filter values.
How can I persist values from controller to controller?
Should I use Session? TempData?
I am using Structure Map for IOC.
Maybe I could have a class that contains a Property for each Session Value that I use in my application and inject it on the controllers that need session?

Is it possible to change a parameter's property after the uer has made a selection or filled in another parameter field? I'm using VS2005
Case:
- 3 parameter fields; Country,Station,Carrier all three are textfields and are allowed to stay 'blank'.
- When the user enters a Country-code in the 'Country' parameter field, the 'Carrier' parameter should become a required field.
I did some searching on the net, but haven't found the solution. I started to wonder if it's actually possible?
I have a parameter Owner with 1,2,3 options in dropdown.
On selection of option 1 , a country parameter should be enabled with all countries' values defaulted.
Option 2 should enable Region parameter with all the Regions values selected and country parameter should be displayed.
Option 3 should disable both Region & Country Parameter.
I am using SSRS 2005 with Enesys tool as add on.
One of our customers has a report with a single value string parameter that has over 1000+ possible values. selecting single value from 1000+ choices results in bad UI, among other things.create another parameter that acts a filter for the other parameter. So you would have Param1 with say 25 choices and selecting a choice would narrow down the option for the second parameter.Is this the best way. What is the best practice for handling these kinds of parameters?
View 5 RepliesSay I have several Areas that are baed on user roles.Differnet roles have different functionality, but also have some "shared" functionality like say "Payments"Now, I created a PaymentController (and it's views for listing, creating messages) in Shared (not an area) and it works fine.
Would it be possible (and how?) to create a PaymentsController class in one of the Areas, have that inherit the PaymentController Class in Shared?
If I can do this, I can successfully share common functionality across areas, and at the same time extend the derived controller to include some 'area specific' functionality to common shared controllers. (Such as the "REturn to xxxx" text and route of the returnurl, which are a bit more complicated than I just made it sound)
How do you use the http POST method with a Grid View on another page. I am trying to use the POST method to send the ID from the selected row of a Grid View, I am using a link button set to fire the select command and it has the Post Back URL set, from one page and then retrieve the ID value on another page using an Object Data Source. Also, under the Defining Parameters, I am setting the ID parameter to Form Parameter Source and have entered the Grid Views name in the Form Field.
