I am new to MVC. my question is when we add a view to the controller event by doing the right click and add view.then we give a view name and click on add button. where is this information stored that which view is linked to which view?
View 2 RepliesBasically what the title says. I created a new MVC application. I'm trying to add new pages to the site, but anytime I do I get the following error:Server Error in '/' Application.The resource cannot be found.Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
namespace MyAppMVC.Controllers
{
public class ProductsController : Controlle{
public ActionResult Index()

For applications that need to have fastly different view layers, and I would like to still use the idea of the controller. I would ideally like to but the controllers in a Class Lib. and then have only the Views in a MVC Web Application. Taking the model out in this way works well, but I can't find a nice way to split the views and controllers.
View 7 RepliesI'm building a CMS type of application in MVC. I want to reuse my views and controllers for adding/managing content in at least two other MVC sites. Obviously I dont want more than one code base for the CMS stuff. I figured out a way to do so:
Controllers:
Controllers are easy. Nothing more than creating a new Class Library Project and adding your controllers. Be sure to reference System.Web.MVC. In your MVC project just reference your controller assembly.
Views:
Views are a bit trickier. My solution was to add the folder structure to my assembly
CMSViews
CMSViewsWhatever
Then start adding my view pages. For each page, you have to set the 'Copy to Output Directory' to 'Copy Always' (right click -> properties)
Then I created a new class which inherits from 'WebFormViewEngine'. In the constructor I call the base() and then I add paths to the base.MasterLocationFormats and base.ViewLocationFormats to specify the new locations to look for views.
[Code]....
Setup in MVC project:
To get the controllers and views to work from the assemblies, you have to add two lines of code in the global.asax. Under the RegisterRoutes() method, add
ControllerBuilder.Current.DefaultNamespaces.Add("YourAssemblyNamespace.Controllers");
then under the Application_Start() method add:
ViewEngines.Engines.Add(new YourAssemblyNamespace.MyViewEngine());
What I dont like is that the Views get put into the Bin directory when published and you have to make sure to set the Ouput to Copy Always which is going to be a PITA for larger projects with lots of views.
We're throwing together a quick project (CRUD forms) and decided to skip view models and use EF entities directly in controllers and views. Since I'm not used to this approach, I'm confused about handling validation.
For example: a DB field has a length of 25. How does that get transferred (if it can) to a validation constraint in my view? If i was using an intermediate model, I would attach attributes to the model properties and it would work. How would I do this using EF objects directly?
I have a subdirectory in Controllers named Admin, which contains several controllers.
Is there a way to change the route so that I can put all the views in "/Admin" for every controller in the Admin directory? Or do I need to map a route for every single controller?
We have a legacy ASP.NET webforms application that we're engaged in stabilising and removing technical debt from. Is it possible to take a hybrid approach - ie, can ASP.NET MVC coexist with webforms within the same web-project? Are there any gotchas for that? If it is possible, I assume one just has to initialise the routes table, register the ASP.NET MVC handlers,
View 1 RepliesI have an MVC 3 application which uses asp.net authentication. I have just created a custom errors controller and a couple of views for unknown errors and 404's. This works fine when I am logged into the application but if an internal server error happens during logon I would like to display the error/unknown view. However I just keep getting redirected back to the login as I am not authenticated.
I have added a location path for 'Views/Error' to my Web.config to allow access to all users but I am guessing it's the controller access that is causing the redirection.
Is there any way you can allow this in MVC or do I need to think of another solution? Just did not want to add a generic message to the login page as that's what my unknown error view is for.
I would like to ask a plain and simple question about the Model-View-Controller architecture - should the UML Class diagram for my application include all the controllers and views and their relationships, or should it just include my model classes, i.e. the entities that are the heart of the application, you know - like in an ordinary application - i.e. User, Administrator, Student, Teacher, Course, Grade etc...?
View 1 RepliesI am looking for a Library that allows me to create Charts like the "Annotated Time Lines" that are e.g. used on Google Finance. I can't use the Google API because it relies on Flash and my chart should not only work on all common browsers but also be usable with mobile devices like the ipad. I don't need all of the features of Google's Solution, but displaying linked event flags in the chart is an essential requirement and the ability to arbitrarily zoom and pan the chart would also be nice, the latter feature is however not a must on mobile devices and older browsers.
A serverside solution that transparently generates plain image charts if flash (or other client features like canvas-elements) is not available on the client would also be ok, I have asp.net mvc 2 running on the serverside.
An open source solution would be great, but a commercial library or component is also an option.
Consider the following scenario: Page written in classic ASP or PHP, which is rendering a data report (series of HTML tables for simplicity). There is one main database query and then multiple sub queries as the page renders. The report is split into sub panels, which correlate to a sub query. Therefore:
Main database query. Loop over result. For each row, execute sub query and render report panel. How would you architect a similar report using the MVC pattern? This can be split into two parts: Efficiency at database level of multiple queries, which are dependent on values from an outer query. If all data was processed and prepared in the controller, would this also be deemed inefficient if looping within the controller and then again in a view to render. Could sub controllers be used or sub panels, which encapsulate smaller sections of logic i.e. loading data and rendering report panel.
I am using a master page with a treeview control. I have 2 other pages Summary.aspx and Home.aspx
I want the Summary page to be loaded when I run the application but afterwards I want to load the Home.aspx page based on the selected Node change event of the treeview control.
I have placed the treeview control in master page because it has to remian the same for all my pages.
Did I do something wrong? The problem is I am not able to load the pages based on events occuring for Tree view control.
I'm building an ASP.NET MVC 2 site where I'm currently implementing an OpenID sign-up form. Unfortunately, I'm foreseeing a possible security bug/vulnerability inside my architecture.
Here's how I want OpenID login to work:
User requests /Account/Login, Controller sends back OpenIDLogin View. User enters their OpenID into the View, then OpenID authorization takes place, and finally the OpenID is returned to the Controller.The Controller checks whether the OpenID is currently in use by a user in the system or not. If it is, the user is logged in to that account. If not, the registration process begins.
And now, the OpenID registration process:
The OpenID identifier, as well as any other information provided by the OpenID provider (such as email address or name), is put into my custom ViewModel and sent to my OpenIDRegistrationForm View.The RegistrationForm View stores the OpenID in a hidden field to make sure that it gets sent back to the Controller.The user fills in the RegistrationForm View and sends it back to the Controller.The Controller creates the user account and puts the OpenID into the database.
The bug that I see within my architecture is that a user could modify the hidden value in the RegistrationForm View. Thus, they could spoof their OpenID! I will make sure to add another round of checking to the final Registration Controller Action to make sure that the OpenID that is provided doesn't exist yet, but there is still a possibility for spoofing. Can my architecture be improved somehow? I don't want this to end badly...
One solution I'm considering is encrypting the OpenID before I send it to the View and then decrypting it when it reaches the Controller. Should I try this?
I am trying to get JQuery events to work with partial views in ASP.NET MVC. However, after you load a partial view through Ajax, JQuery seems not able to fire events for any of the elements in the partial view. I suspect that this issue will also happen if you are using other frameworks or JavaScript libraries to load partial html code with Ajax.
For instance, consider the following example:
Controller:
[Code]....
Once the page loads for the first time, you can click on the "Click here to display a Javascript message" and you will get a Javascript alert message that says "button clicked". However, once you click on the "Click here to load partial view", clicking on the button that is supposed to bring the Javascript alert message doesn't have any effect. It seems that the 'click' event is not being fired anymore.
why this issue occurs with JQuery and how to fix? This issue also occurs with other JQuery plugins that use events.
Here is what i would like to be able to do with the urls/routes:
1) www.domain.com/customer/home/index
2) www.domain.com/home/index
Where both the home controllers should be seperate controllers with seperate views and the company part should be an param for all the actions in the controllers.Now why i want to be able to do this is because of the following scenario: Each customer will have there own pages (which actually will all be the same for each customer but with different information per customer). The one without the customer is the general website where non customers can go to to become an customer or get information about the services we provide for them, they can sign up etc.
I am learning MultiView control.Here are question:I added 5 views in the MultiView but all views are tight together. I can not drag and drop another control such as text boxes or labels into view area.
View 15 RepliesI have an MVC view that contains a number of partial views. These partial views are populated using partial requests so the controller for the view itself doesn't pass any data to them. Is it possible to reload the data in one of those partial views if an action was triggered in another? For example, one partial view has a jqGrid and I want to refresh the data in another partial view when a user selects a new row in this grid. Is there a code example for this scenario (in C#) that I can look at to see what am I doing wrong? I am using ajax calls to trigger a new request but non of the partial views are refreshed so I am not sure if the issue is with the routing, the controller,
View 1 RepliesI've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
View 4 RepliesSo I've got a databound grid view within a UpdatePanel.
the user can change the data within the gridview then click a save button to update the data within the database.
However in order to know which rows have been changed I have a textChanged event associated with each textbox, but the event isn't being fired.

i just want to use a calendar with events like date selection update,delete,creat events. and i want to do this with sql server 2005. I started my project with webApple.

the problem line is

I have been tasked with designing a scheduling system to fit into an existing application. At present I have a SQL Table - Tasks which have a StartDate and EndDate column.
I have a requirement to set the Task as a recurring task i.e. Replace server backup tapes every day, or, Order more stationary once a month.
I am lost on how to design this. I can't seem to find a proper example on the net. can someone point me in the right direction.
I have a page with 2 Controls, a ListBox and a DropDownList.
In the DropDownList you can select a PLACE.
In the ListBox you can see all DOCUMENTS for the selected PLACE.
If you select a DOCUMENT, the program does a redirect on the selected DOCUMENT.
So, there are an AutoPostBack and an Event (if you select another Item) on both Controls.
The problem is: If I select a PLACE, then I select a DOCUMENT (the pdf document is opened), and then I go back on the page and I want to select another PLACE, the program doesn't select another PLACE, but opens the old DOCUMENT, because there are 2 Events, one to change the PLACE and one to open the DOCUMENTS.
Can I give a priority at the Events?
Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)
1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.
2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.
3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.
I have 2 tables with a many to many relationship directory and website, they are linked by the table dw, the dw table has extra filds that are relivant to the link it is not simply 2 forain keys. So in my entity diagram i can see all 3 tables.
