MVC :: Handling Validation Differently For Each Action Method?
Jun 30, 2010
I am new to this MVC and have a basic question related to validation. I have a create view for customer and based on the customer entity partial class metadata, I am validating the user input and its working fine as expected when the user clicks the create button.I also have a search button in the same create view, which is used for auto generation of some of the field values. When the user clicks the search button the action method create (post) is called with the corresponding button value as argument.the issue here is when the user clicks the search button most of the user input fields will be blank and the validation fails because of that.
I am desiging a master and details page from a search page..user can search for something and I need to display the result in jqgrid if the result has more than 1 row or record.. if the result is just one record then i have to directly send then to details page by skiping grid page... I do have an action method for results page and one more action method for Jqgrid data..i am trying to check the row count for the database result and trying to redirect to details action results..but its not working at all..and showing an empty jqgrid..
I have an ASP.net page. That has an Ajax Toolkit Tab Control.hat has tabs.That have custom ascx controls I wrote.I have a text box that perform a search action. It is declared like this:
Nothing fancy. This format has been working for months. There's no submit button. It just posts back when I hit enter. The problem appeared when I added a second custom control using the same type of feature. Now browsers don't postback when I type something in either of these textboxes and press enter.It seems that browsers have a default way of handling one textbox in one form, but that behavior changes when the number reaches two.Is there an easy way around this? I guess I can create a hidden submit button but it seems like there is probably a better way to deal with this when the functionality is in two separate custom controls.
I need to create application wide error handling mechanism. I was evaluating Action Filter for that matter. But- Action filter will just exectute against actions/controller- what about error at custom view engine or Extension method for HTML helper.: to handle them i need to implement traditional Asp.net mechanismCan anyone suggest best common approach which can handle error for all Controller, View, Model or custom helpers if any.
I currently have a project that I seem to have ran into an issue regarding Roles and thought I would get some opinions on how to best handle the problem. The system will require editable, flexible roles that control not only the access of specific areas, but also the use of system functions (Adding Users, Editing Users, Viewing Reports etc.)The system currently allows users to have multiple roles, each of those roles has explicitly defined areas of access/actions, for example:
Role A can access areas 1,2,3 and can Add Users. Role B can access areas 1,5,7 and can Modify Users. Role C can access areas 4,6 and only View Users.
so a User could be in Roles A and C, and thus access : 1,2,3,4 and 6, and could Add and View Users.My first solution was to create a dictionary that would store all of the possible areas of access/access options into a Dictionary like so:
Dictionary<string,bool>
then when it is instantiated it pulls all of the properties from the database and then iterates through the roles to determine if they are accessible.All of that currently works just fine - however the project is quite Javascript/jQuery intensive so many of these options are called by client-side functions. I am trying to avoid having to wrap all of these client side functions with:
<%if(AccessDictionary[key]) //Enable or Disable Action <%}%>
I am wondering about the following things: After a user logs in, what is the best way to store this Dictionary? Statically? In the Session?What would be the best method of storage such that the Dictionary will be easily accessed in the View? (As I currently see no way around wrapping my client-side functions)!
I've been using the new ASP.Net MVC 3 RemoteAttribute to send a remote call to an action method that had a single parameter. Now I want to pass in a second parameter using the AdditionalFields property:
I have 2 views for a input operation in my application.
The first view (lets call it view1) submits a form. Based on the form some operations on database is done and second view(View2) is returned with some other data from the database as a model.
[Code]....
Now, since I return a new view and not a action redirect the url is still http://url/View1 but everything works as it is supposed to.
When I submit the form in View2 it calls the View1 action method, not the View2 action method. Probably because the url is still View1.
Secondly, how does ASP.NET MVC know that action is my action, and controller is my controller. Like I saw this in samples, and it does work, but isn't it just an anonymous object with no type?
I'm trying to use the jQuery.post() function to post an object to an action method, but for some reason the nested objects aren't initialised properly when they're received by the action method.
Here's my javascript code:
[Code]....
And my action method:
[Code]....
company.Id has a value of 10, but company.User.Id is 0. what I'm doing wrong? I've not named any properties incorrectly, by the way.
I have an ActionResult that accepts POST, however is there a work around for me to redirect from a controller to another controller containing this POST method/action?
I have a controller called Person and it has a post method called NameSearch.
This method returns RedirectToAction("Index"), or View("SearchResults"), or View("Details"). The url i get for all 3 possibilities are [URL] How would i change this to rewrite the urls to [URL], [URL] for View("SearchResults"), and [URL].
i just want to be able to call a javascritp subroutine on the client, after the server has done its thing (when an action completes or control goes to the view, i'd dont mind calling the js from the view either).
for some reason, even vs2010 doesn't let me put breakpoints in <% ... %> tagged areas between <script...> and </script> tagged areas. i for this reason can't figure out whats going on and how it's running things. here is what i've put in my view, and the javascritp should run, but it doesn't....
im just trying to call "RunOnceRoutines;" but it's not getting called!
the 2 questions: how on earth do we call javascript methods from server, and where is all this lovely javascript debugging i've heard about since vs2008? no where to be found!
In one view (view1) there is a text box and a button beside it. i click on that button, i am popping another view (Create view) as a seperate window. in create view i am entering some values and creating a record in db. out of these values one value i have to send back to "View1". how can i send this value? i am opening view2 from view1 like
View2 contains some fields like Name,Email etc... and I click "Create" to call HTTPPOST. there i add the values to db including a generated guid. i want to send this ID to view1.
Movie has fields Id, Name. View is displaying name only in textbox. When button is clicked, the above action method's movie is populates with the updated name value but Id is 0, actually that record's id is 4. Thatswhy my updating of record is not working. Why MVC is putting 0 into id?
I'm struggling with renderaction, the problem is that it calls the wrong action method on my controller.On my "Users" controller there are two action methods called edit, one for get and one for post requests:
public virtual ActionResult Edit(int id) { //return a view for editing the user
for debugging purposes, how do I see the ModelState errors from code in the action method? ModelState.IsValid returns false. I want to copy the error messages to a variable so I can display them in the debugger.
I know this question has been asked million times but I think my situation is different here.I am using .NET Framework 3.5 SP1, there is no form action on the page and it's not happening when I try to submit the form quickly. I am not on a web farm either.I have a page with two GridViews. One Gridview acts as a master gridview and second as detail gridview. First Gridview has autogenerate select button and clicking select would bring related records in detail gridview at the bottom. I have a refresh Link button at the top. Everything works fine. I click refresh button and it works fine too.Ok when problem start happening when I leave the page idle for like 10 minutes or so and then I click Refresh button only then I get this "Validation of Viewstate MAC failed" error.
