MVC :: Trying To Use TheRemote Attribute To Perform Remote Validation
Jan 25, 2011
I have been trying to use the [Remote] attribute to perform remote validation in MVC3, but the namespace/type cannot be found. I thought it was in the System.ComponentModel.DataAnnotations assembly, but I have checked in the Object Browser and I can't find it.
Is it need to use HttpWebRequest? how does it works? i want to pass data from a asp.net page's textbox to a textbox in a given URL/ a given website, how can i do it? For example, i want to pass a text box value which is entered by a user in my asp page, then the textbox value will be passed to the website's text box and get the response. I want to pass some data to a website-for example [URL] then call the submit button of the given website from my ASP.NET page, then get response from it.
Which means when user fill in the textbox in my asp.net page, [URL] the hotel search textbox will be auto fill in with the data (such as the date) that user typed in my ASP.NET page. and this will call the submit button of the website, so that the given website can response.
I have inserted a login page using createuserwizard. but RequiredFieldValidator and CompareValidator does not perform at all and even all textboxes are blank, page is submitted and a record created in database
We're trying to get a conditional attribute to work, case in point, there's a boolean (checkbox) that if checked, its related text is required. So, ideally we'd have something like ...
public bool Provision { get; set; }
[ConditionalRequirement(IsNeededWhenTrue = Provision)] public string ProvisionText { get; set; }
Is this even possible?
Alternate idea (not as elegant?) public bool Provision2 { get; set; } [PropertyRequired(RequiredBooleanPropertyName = "Provision2")] public string Provision2Text { get; set; }
I'm creating a simple login functionality on my own.
I have a 'Users' Model class, that contains UserID, Username and Password and I want to put some validating attributes to my properties. I put [Remote] attribute to validate whether the username is duplicated.
[Code]....
And 'ValidateUserName' is checking for duplication like this:
[Code]....
I have 2 strongly-typed view that are using the Users Model. The first one is for User Registration which is working fine, i.e. not allowing duplicated user names.
But the second one I use for User Login and when the user writes his name a validation error is thrown that says that the Username is taken (which is correct). But I want the Remote validation to fires only when Creating new user. Do you know how to do this?
I have a form where users enter their preferred contact method. It has:
- a radio button where a user selects whether they'd like to be contact by phone or email or either
- a textbox for the user's email address
- a textbox for the user's phone number
I have validation via a custom attribute that verifies that if the user selected phone they entered a phone number, if they selected email they entered an email, etc... but it's at a class level on my ViewModel. As such the validation doesn't mark the expected field as invalid.
Is there a way that my IsValid override (or some other method) can mark the child property's value as invalid so I get highlighting?
when sending email the' asp.net 2.0 i get the above error msg The remote certificate is invalid according to the validation procedure. how to rectify this error msg soemetmes i get this error msg also Mailbox unavailable. The server response was:: bosauthsmtp15: Host :No unauthenticated relaying permitted
i have created a mail application as a part of an support application for my company.when enabling ssl it is showing the error as "The remote certificate is invalid according to the validation procedure"when commenting enablessl its working fine and mails are going. i know that the problem is with ssl autentication. i have made no changes to web.config file.
MailMessage msg = new MailMessage(); string[] a = mailto.Text.Split(','); oreach (string str in a) [code]...
The function below works in a console application but it's not working in my asp.net web site. I am getting an error:The remote certificate is invalid according to the validation procedure.
public static void SendEmail(MailMessage mm) { SmtpClient smtp = new SmtpClient(); smtp.Host = "smtp.gmail.com"; smtp.Port = 587; smtp.EnableSsl = true; smtp.Credentials = new NetworkCredential("ma@mail.com", "Pass");
I have an CustomViewModel that is composed of three layers of objects.
The first one is to store and populate lists to be used in dropdowns.
The second one is to store additional propperties that I want.
And the third one is the model itself.
I create the view using View(new Layer(model))
And at the post i have ActionResult .... (Container container)
I made this architecture because i was having a lot of problems with model binder and enums...
So when i post to the form and the ModelBinder checks the validation attributes, the IsValid operation at the attribute X applied to the model class has its parameter value as null.
This behavior doesn't happen if I Just use the simple model to create and post the view.
What I have to do to get this work ?
I made a few changes to the AccountController to use it as sample here, here is the code:
[Code]....
Just change the register page to inherits from RegisterModelLayer.
When I post, the value parameter at the IsValid function at the PropertiesMustMatchAttribute class is null;
As a consequence i can't validate and get an null exception maybe.
I have used a pattern of compound view models for a few of the forms in this project. It works very well.
In this case I have a VendorAddress view model. I use Address(es) in a few places in this project so I made and Address view model object that I can re-use. Then I desided I want to do a very thorough checking of the state codes and zips so, I desided I would try to use remote validation and check the state and zip code aganst a stored set of tables in the database.
The problem is I am not getting values back to the remote action methods for the fields I'm asking for (in this case State and PostalCode). I believe this is because of the name mangleing that the MVC framework does for compound or sub types for id(s) for the inputs in this case it is making names like 'Address_Line1' and 'Address_State' and 'Address_PostalCode'.
Ultimately the question I have is, is there a way of turning off the pre-pended 'Address_' from the base view model object in a way that MVC framework can put it bak into the object after ther post of the form?
[Code]....
Then in the form after rendering it looks like this:
[Code]....
I get the remote call but there is nothing in the parameters "State" and "PostalCode", so the unobtrusive routines are firing but I think it does not know where to look for the data even though I have type something in the mensioned fields. As you can see in the rendered code the id="Address_State" and the data-val-remote-additionalfields="*.State,*.PostalCode"
I created a simple Master Page in Visual Studio 2008:
<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
and got green underlined 'Master' with two warning messages: 1.Validation (ASP.NET): This attribute name must be followed byan equal (=) sign and a value. If the value is in quotation marks, the quotation marks must match. 2. Validation (ASP.NET): Attribute 'Master' is not a valid attribute of element 'Control'.How I can get rid of the messages?
i'm trying to host an .net framework4.0 application in IIS7. i got an error while clicking on the manage module in modules .like ("Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive. ") .I changed my application poll to .net4.0.I am able to browse my application
I installed Microsoft Visual Studio 2010 Ultimate Trial and converted existing asp.net 2.0 web application and I am getting this error: znrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive. It's coming from this section in the web.config which was auto-generated by VS2010 when I converted the project:
I am developing asp.net mobile application. I am using LINQ to XML to query XML file. I am using the following query to retrieve the name & value of the query dynamically as follows
var TotalManifolds = from MF in FieldRoot.Element("FIELD-DEFINITION").Element("MANIFOLDS").Elements("MANIFOLD") join SLT in FieldRoot.Element("FIELD-DEFINITION").Element("SLOTS").Elements("SLOT") on (string)MF.Attribute("MID") equals (string)SLT.Attribute("PARENT") select new { SlotName = (string)SLT.Attribute("NAME").Value, SlotValue = (string)SLT.Attribute("NAME").Value };
In the following statement of above query I want to retrive the name of the attribure dynamically without explicitly specifying the name of the attribute SlotName = (string)SLT.Attribute("NAME").Value Here I am explicitly specifying the name. I want to code which can dynamically retrieve the name of the attribute. I am new to Linq to xml. how this can be done programatically? or can you provide me the link through which I can resolve the above issue ?
