Proper Way Of Using FormCollection In .NET MVC2 Create Method?
Jan 28, 2010
I am currently developing an application with the new ASP.NET MVC2 framework. Originally I started writing this application in the ASP.NET MVC1 and I'm basically just updating it to MVC2.My problem here is, that I don't really get the concept of the FormCollection object vs. the old Typed object. This is my current code:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(FormCollection collection)
{[code]....
What are the benefits of switching to FormCollection in MVC2 and more importantly - how is it used properly?
Can you point me to a url for the proper directory structure to create for a new website?I can create a website project and add class library projects to the solution to create a fully functional website.My grey area is that I need to zip up the web site solution and hand it over to the client.I'd like to make sure that I hand over a solution with the most proper directory structure.I'll run you through a scenario:
1. Select File > New > Web Site > ASP.NET Web Site from the main menu 2. Save with a path of C:ProjectsTestWebSite 3. Right-click the solution in VS and select Add > New Project > Class Library 4. The new class library is added with an automatic path of C:ProjectsTestWebSite (2)MyClassLib1
It seems like there should be a way to create a better structure for this but I'm just not following the correct process. Can you point me to a url with instructions for managing a proper structure for this?
What is the correct procedure to create an n-tier Website in ASP.NET? Can this be done without setting up a server farm, and how would you be able to test it?
I am trying to write a simple library for MVC2 projects that takes care of user login, e-mail validation, password recovery, logging, etc. Since some of these steps involve user interaction, I need to have Views and Controllers in that project.In MVC2 Preview 2, one could do this by abusing areas (at least, it seems) since they were implemented as different projects. However, in the RC, creating a new area will merely create a subfolder. Since I want to share the base code between applications, that is not an option.I tried to brutally hack the AfterBuild steps into my project files, but that feels like the craziest hack ever.
am trying to create view form in my MVC2 applicationIn this i have a submit button which is an imagebut when i try to run it shows a normal windows button the image is not shown(the image is a round edged).the code is as below:
I added the extender and when i tried to add the method this message poped up; Cannot create page method "GetCompletionList" because no Code Behind or codefile was found.
Ive got a scenario where a form is filled in and the action picks it up as a FormCollection. It then carries out validation on it and if it fails sends it back to the form again, however i cant seem to get it to re-populate the form.
If i do something like:
[Code]....
So it just looks for name in whatever is passed over... ideally i dont want to involve a model unless it has all validated fine, but if there is no other way around it can populate a model and do the validation on the model instead...
FYI I am using .NET 4.0 / MVC 3. In my controller, the following is my code:
[HttpPost] [ValidateInput(false)] public ViewResult Edit(ContentTemplateView contentTemplateView, FormCollection collection)
Everything works fine when I don't enter HTML, so I know the proper controller is being fired. Also, I have following set properly in my web.config files:
<httpRuntime requestValidationMode="2.0"/>
I only get this problem when I include the FormCollection (which is needed for this particular Controller). So what exactly am I doing wrong? [I have done what was proposed on the following questions, and they work as long as there is no FormCollection. None of them offer a solution with an included FormCollection] Why is ValidateInput(False) not working? Asp.Net MVC Input Validation still firing after being disabled ValidateInput Attribute Doesn't Seem To Work in ASP.NET MVC
My application writes custom attributes to input controls using Helper classes. And also we are loading the UserControl dynamically so we need to use FormCollection to get the posted values. Is there a way that we can access attribute values from FormCollection object.
I'm overriding the OnActionExecuting method in a base Controller. When a form gets posted - anywhere, I want to check for a certain form element in this method. In any Controller method I can just include the FormCollection as one of the params in its signature, but if I try that with the OnActionExecuting method I get an error saying that there's no suitable method to override. How can I get past this?
I want to know which fields were edited in a form in the Edit Action. I have a Log field in a table named "someTable" which I wish to add the change to, along with the Username of the current user. This is a simple implementation:
[Code]....
Can someone tell me where I am going wrong, because the getChangedAttributes function always returns an empty list (assuming because "backupTable" and "form" contain the same values? But shouldn't they be different?
I'm using jQueryGrid and an Action method to populate search results based on some filter criteria, how to pass this form collection values to Action method from Javascript function.
I have a strongly typed view for my User edit action. When I press edit all the fields in Users model is filled with values from the DB. If I enter an invalid data for a particular field say email, then the view throws an error, but after that the email field contains data pulled from the DB and not the one which i entered previously.
I will explain to you in steps if my explanation is confusing.
1.Click the edit action. 2.A page displays with all fields in my User model. 3.Email field contains : johnson@company.com (pulled from the database) 4.I try to change the email to "johnson@company1" (This is an invalid email id) 5.The form does a post back and return an error saying that email id is invalid. 6.Email field contains : johnson@company.com (pulled from the database) and not "johnson@company1"
Is there a way to convert the FormCollection to an User model and send it back to the view?
Now I see that this renders both the checkbox input tag and a hidden input tag. The problem that I am having is when I try retrieve the value from the checkbox using the FormCollection:
FormValues["ReceiveRSVPNotifications"]
I get the value "true,false". When looking at the rendered out HTML I can see the following:
I have a basic form that renders data out to a form like so (from Northwind):
<% using (Html.BeginForm()) { %> <h2>Region Selection</h2> [code]....
In addition, I have a controller that is called when the form is posted back:
[AcceptVerbs(HttpVerbs.Post)] public ActionResult Index(FormCollection collection) { [code]...
The problem is that none of the data in the table is being captured in the FormCollection in the Post. The TextBoxes pass data as expected so I know the wireup is working.I read from some other posts that you need a value for the name property - but that did not work. Also, I read that you need to put the data inside a TextBox inside the TD. Instead of grasping at straws, does anyone know the best pattern to pass the data from a Table back into the FormCollection?
btw: I tried to copy/paste formatted test in from Word. No dice. Ugh.
I'm passing a List to an MVC view and generating checkboxes for each object in the list (The checkboxes are named t.Name).I'd like to be able to tell which checkboxes were checked once the form is posted. However, I'd like to avoid using the FormCollection object.
can I create more than one method on a web service? Because the other method does not exist when I set my web service to be the start page. I created a web service for my autocomplete.
I know there is a ListBoxFor extension method among the ASP.NET MVC Html helper extension methods, but I always thought that a checkbox list is more user-friendly than a list box.
There was a very convenient CheckBoxList control in good old WebForms, but obviously that is out of the picture now. The question is, why is there no way in ASP.NET MVC to create a check box list? How can I write my own extension method that creates a check box list and behaves in a similar way ListBoxFor behaves?
