I 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.
I have a controller method that is called with many different combinations of URL's. To overcome issue i am using optional parameters.here is my controller method signature...public ActionResult localMembersSearch(string Gender, string calling, [Optional]string Region, [Optional]string County, [Optional]string Town, [Optional]string queryvalues)the first two parameters are not optional but always expect
I have got a problem about setting the optional parameter to NULL in sql sp. Initially I set all the parameters null in the sql sp. That's OK. But I would like to set the parameters to Null again if a particular parameter has a value of - 1 by using the "IF ELSE" statement block. However, the problem was that I was unable to set the parameter to NULL in the IF ELSE statement. So please correct my IF ELSE statement in the store procedure. This is really urgent and important for my project.

I'm starting a port of an existing ASP.NET Web Forms CMS to ASP.NET MVC and want to get the routing right from the start.Note: it isn't important to have the exact same URL structure.I think this answer is close to what I'm looking for but would like some additional input should anyone have it.
am to add optional parameter to pass these in a method the parameter may vary every time.And i need to pass these parameter to a method, so my question is how should i add these optional parameter to a collection and what kind of collection object should i use and how should i use that.
I would like to have two different welcome pages for a site.How could I handle this? I've looked at routing but I'm not sure if global.asax.cs is the correct place to place this into.
www.mycompany.com should display generic information. Displaying view Home/Default.aspx www.mycompany.com?id=1 should display welcome customer x. Displaying view Home/Welcome.aspx
I was expecting a parameter will become a empty string value if the parameter is missing, but it turn out to be null. have I done it wrong for the optional parameter?
Basically I have RegisterModel2 that has a Person class. My requirement is that Phone Number and Address are not required for registration. But if they try to enter a Phone number of Address then it should validate it. Problem is that it is always stating that the child fields of Phone (area code, number) and child fields of Address (street1,city,etc) are required. Is there a way to annotate in the RegisterModel that a parent class is not Required but if any data in a child element is given then and only then should the child elements be validated?
My Person EDM class has a nullable 0.1 -> 0.1 navigation property to Phone and Address.Here is the person class
[MetadataType(typeof(Person_Validation))] public partial class Person { }
public class Person_Validation [code]....
The Person EntityObject has an optional/nullable Navigation Property to the Phone Object.
The Phone object has these annotations,[Code]....
I have RegisterModel defined as follows: [Code]....
My View looks like this: [Code]....
And here is my Controller Action it is posting to: [Code]....
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 have a stored procedure with multiple parameters. and several statement which utilities a specific set of queries. therefore, every time its not necessary data will be passed through the parameters, so how can i make "providing data to parameter" optional
I'm creating a reports with the following filter criteria:
ID - textbox Created Date - range between start and end date Syste Name - dropdown Users may filter the report based on the ID or System Name or all the criteria mentioned.
The search Field for ID, by default has a Null checkbox beside on it while other filter doesn't. how can I enable the checkbox for the other filters?
So I came across this article which should my issue. Apparently, I'm receiving a formula error "The arguments to the following functions are not valid:FIND" with this formula OR(FIND(Creation Date, Parameter: Creation Date)<>0, Parameter : Creation Date = Empty). see this link for the screenshot. I don't know what I'm missing. I'm using Reporting Services 2005
I'm trying to have a parameter as optional i.e. /Category/{ProductName}/{ProductOption} where ProductOption is optional. How do I handle this in web forms 4? Here's what my code looks like now:
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:
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?
UML 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.
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 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?
