How To Pass All The Local Variables In One Controller To View
Jan 16, 2011
In asp.net mvc3, I've got a few local variables in one of the controller, is there any neat way to pass all these variables to view? Something like "locals()" in python?
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?
Each row has a drop down, a text box and an "add" link. I'd like for someone to select something in the drop down, edit something in the text box and pass that information to an Action in the Controller.
I know i can do something like this:
[Code]....
[Code]....
Which is kind of gross - id like to do just call one action, that passes the selected drop down value, the textbox value and call just the one action, is it possible to do something like this:
[Code]....
Where i pass the Dropdownlist selection and the textbox value to my controller specifically
now, what i want to do is to place few textboxes on a view that allow users to input the Answer Text. after click the submit button. i want List<AnswerInfo> which contains the Text information pass to the controller. can anyone tell me how to do it?
I am Francesco and I am newbie. I have a problem with ASP.NET MVC3 regarding the data posted between View and Controller. My goal is to use a form to edit a specific record from my database and then post it back to the controller, which is in charge of checking the record's fields and submit them into the database. The data are passed from the Controller to the View by using a ViewModel and therefore the DefaultDataBinding does not apply in this case. I tried many approaches, I monitored the communication with Fiddler but I couldn't solve my problem. The method described by Phil Haack does not work and neither does the FormCollection.
Here you have the code:
ViewModels: I pass it to the View to create a table. Name and the list of Item names (table columns headers) are just to be displayed. I want to have back the Id, the Month (they are passed correctly as parameters and represents table row headers) and most important the ActualValue of the Items and their Id (I have an association table in my database with Id, Itemid and Month as keys)
[Code]....
View: The View is strongly typed as ViewModels.EditViewModel and sends the fields through a submit button. I have to generate a table by using foreach loops, because I do not know how many items there are in advance
Controller: The controller has to update each kpi passed from the view related to a specific Id and Month.
[HttpPost] public ActionResult EditMonth(int Id, int Month, //FormCollection kpiValues)
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"?
if I use a Html.Hidden field in my view, when the value click to submit the form I would like to pass this data to the controller. This variable would contain int as key and string as value,
Dictionary<int, string> interestTable = new Dictionary<int, string>();
How can I specify the htmlAttribute fo this variable in my Html.Hidden code?
One small doubt in the way it works for C#Where does local variables of a method inside a class get stored?Heap? - If yes, then why do we have to explicitly initiate them?Stack?- Then how does the allocation of them takes place once we make a object of the same class using new - would it make the member variables of class to be allocated on heap and local variables of member functions (of the same class) on stack.
I'm calling an action from another controller using this code
[Code]....
But inside "ApproveOperation" action, I needed the Session variables. It seems when I called it from another controller (not the owning controller), the Session variables can not be accessed (null value).How can I get the same Session variables just like it was called from the owning controller?
I'm fairly new to MVC and admittedly don't fully understand how data is passed between Views and Controllers. That said, here is my issue.
I am working with C#. I have a page which has a list of items. Each item has a radio button set of three associated with it and there are 15 of these sets on the page. Thus I have radio1, radio2....radio15, etc. Each of these has value 0, 1, or 2 upon submit. I can't seem to understand how to get the information out of these radio button sets from the controller without passing 15 different variables to the post method in the controller which is associated with the view; ie passing Int32 radio1, Int32 radio2,.., Int32 radio15, etc.
I tried using ViewData["radio"+i] in a loop to access the value of each radio button set, but this, apparently can only be used to pass data to the View from the Controller and not the other way around.
Can i create a partial view and a controller that will feed data to the view, and if i render that partial in a Master page, the Data will show on whatever URL i am?
Or is there another way of showing content from database on every page(view)?
I have been reading up on this all day, and I can't find the answer (or more likely, don't understand the answers I have found) to my problem. I am completely new ASP.NET and trying to make a trasition from Classic ASP.
In classic ASP it was possible to 'pass' variables between include files. In ASP.NET includes are very different. I'll keep this simple:
I have 'header', 'content' and 'footer' pages. The header and footer are both 'includes' in the content page.
I want to be able to pass a variable from the header to the footer. Heres a snip of my code so far:
[Code]....
[Code]....
[Code]....
However this errors crops up in the footer when run:
Compiler Error Message: BC30451: Name 'helloworld' is not declared.
So how do I make this variable available to the pages involved??
I imagine there is more than one way of doing this for many circumstances.
Is it possible to postback to the server, perform a function, and then continue that postback on to an external place? (ie, to a payment system)(the scenario is clicking a button to place an order, mark it as sent, then send them off to the payment page (there are form variables that needs to be sent to the payment screen as well))
I have never passed along variables to a function before. I have a function here that should return true or false.
My question is, how I do this in a realtime example. How do you pass along the 4 string variables to the function and see if cbValid is true or false ?
