It appears that must use a string as the error's key. Is there a way i can generate the corect key from the model, or should I just check for what input name Html.PasswordFor(x => x.NewPassword) returns?
Showing Modelstate Errors While Using RenderPartialToString?
Apr 29, 2010Im using the following code:
[code]....
To return a partial view and a form through JSON. It works as it should, but as soon as I get modelstate errors my ValidationSummary does not show. The JSON only return the default form but it does not highlight the validation errors or show the validation summary.
Am I missing something?
This is how I call the RenderPartialToString:
string partialView = RenderPartialToString(this.ControllerContext, "~/Areas/User/Views/Account/ChangeAccountDetails.ascx", new ViewDataDictionary(avd), new TempDataDictionary());
PropertyName Not Showing Up In ModelState.errors
Apr 8, 2010Imagine, a model like this:
[AddressValidation]
public AddressType[] Address { get; set; }
internal class AddressValidation : ValidationAttribute
{
public override bool IsValid(object value)
{
//Assume we are valid
var isValid = true;
//Cast to something useful
var addresses = (AddressType[])value;
var defaultAddresses = addresses.Count(a => a.AddressCode == AddressCodeEnum.@default);
if (defaultAddresses == 0)
{
ErrorMessage = "One address must be the default address";
isValid = false;
}
else if (defaultAddresses > 1)
{
ErrorMessage = "Only one address can be the default address";
isValid = false;
}
//Return the result
return isValid;
}
}
When the model is validated by the controller, any of the subordinate addresses are properly validated and any errors are returned as modelstate errors. However, the custom attribute's error is never added to modelstate, even though it validates false. It seems as if this should work, the validation is called and I can step through it - it just never gets added to modelstate.

View 3 RepliesMVC :: Returning View When ModelState Not Valid
Feb 25, 2010I've written a View (form) that has a section with two radio buttons and a blank <DIV> block that will dynamically be updated. When one radio button is clicked, a <DIV> on the page is updated with fields specific to that radio button option. When the other radio button is clicked, the <DIV> on the page is updated with fields specific to that radio button option. To determine what content gets displayed when a radio option is selected, I call a JavaScript function and set the content appropriately using jQuery. Pretty easy so far. Let's assume that the User has toggled the radio buttons and filled in some data. Further down in the form, the User has entered an invalid e-mail address. When the User submits the View, the ModelState is invalid. If it is invalid, I return the View.
[Code]....
Problem is, when the View is returned, some of the form fields (that are static) are in place. However, the <DIV> that was previously updated based on User radio button selections is reset to its original state. When we return a View because of an invalid Model State, is MVC smart enough to return the View in it's modified state (in this case, with the modified DIV and dynamically added content)?
MVC :: How To Run A Test And When It Returns A View When ModelState Is Invalid - Nothing Shows Up
Jul 26, 2010I've been working with MVC 2 for awhile and ive done ReturnToAction as well as ValidationSummary - but this is a little different in that my "submit" buttons are controls by javascript/JQuery - i debug the action and it does go into the correct Controller Action but once it passes over RedirecToAction, nothing happens....
My second problem is that my ValidationSummary fails to show - i run a test and when it returns a View when ModelState is invalid - nothing shows up
Is it a problem with my buttons/forms/submit/JQuery?
[Code]....
And the Controller looks like this:

My Services handle things like validation, I pass it the ModelState and a ModelStateDictionary wrapper and add errors - am i adding errors incorrectly?

MVC :: Partial View In Modal Dialog (using Ajax/jQuery) - How To Handle Invalid Modelstate
Mar 18, 2010After wading through quite a few articles on creating modal forms (using partial views and jquery) I got things working fine for my login....as long as you enter a valid login though!
What I did:
Created a partial view containing my login form.
In my action controller, the get action just return a PartialViewResult, which get dealt with by a bit of jQuery in my master:[Code]....
Like I said this works fine. Now the post action of my login check if it's a valid login, and if so send the user to the passed returnurl or the home page.
However, if the validation fails, I now return the partial view again, which work , but the partial get displayed by itself instead of rendering in the modal form that was opened by jquery.
When Try To View The Files In VWD 2008 Get Various Errors, Depending On Which Page View?
May 5, 2010I'm being tasked with making changes to an asp.net application and really have no experience working with them other than dabbling in VWD.I was given a zip file of the directory containing the files.

The application is functional on the web server.
View 2 RepliesTrying To View Jpg In GridView But Encountering Errors
Feb 2, 2010I tried to follow the example here: [URL] I pointed my .aspx page to Northwind > Employees, because that table already has a field for pictures, and a few data points, so I thought it would make sense to use that. I followed the instructions and set my DataImageUrlField to ProfilePicture. I'm not sure where the images go, or even where 'ProfilePicture' goes, so I created a new folder in my project and named the folder 'ProfilePicture' and put the pictures in there. So, now I have this kind of setup: C:Documents and SettingsThinkPadDesktopWebSite1Profile_Pictureimage1.jpg
Then I loaded the page and all data loads into the DatGrid fine, except for the images. So I copy/paste the code into 'Default.aspx.vb' and I debug and get this error: Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

View 1 RepliesHow To Return Errors To View From Controller Not Tied To A Specific Model Property
Aug 26, 2010Curious what the best practice is for returning errors to a view from a controller where the error isn't really a validation error, but more like "user not found" or "service timeout" type of errors. (in ASP.NET MVC2 framework)
I've been adding them to the ModelState's model errors, but that doesn't seem appropriate. (although easy to implement and maintain)
Example - A user tries to log in, and their credentials do not match a known user.

View 3 RepliesWill CLOB Data Be Truncated When Displayed In A Select Query? If So, How Can It Be Displayed
Jul 1, 2010I've got a Varchar2 field in my table which I want to convert to a CLOB. I am unsure whether the data would get truncated when selected. If so, what is the limit and does it depend on the database settings?
In my TOAD or SQLPLUS window it gets truncated but this may just be the environment settings. I'm not sure whether it would get truncated in my actual application (I can test this, but up to what size should I test?)
If it does get truncated, what's the best way to display the whole CLOB? There are other fields in my SELECT query, so I think I can't just loop through multiple rows. Is there any way out?

MVC :: Using ModelState With RedirectToAction?
May 18, 2010I have created a custom validation attribute for a class. The validation is actually against one property of the class, but since it needs to be compared to another property of the class at runtime, I had to pull in everything from the input form, perform the validation and output the errors. This being the case, I manually added a ModelError to ModelState if the ModelStats.IsValid returned false. I have another thread that goes into this, as I still haven't been able to make the client-side validation work for the custom validation (built-in validation runs client-side without a problem).
Here's the issue: I want to use the Post/Redirect/Get pattern to avoid issues where users refresh their page and cause another post of the form data. If I complete my Controller action and return a View after assigning an error with ModelState.AddModelError, I get the user feedback with the red input field and error message shown. However, just returning a View like this makes you vulnerable to the repeated posts issue. I want to use RedirectToAction to perform a get and avoid this problem, but when I do that I no longer have the ModelState error feedback on my rendered View. Here're the calls I'm making:

I'd like to be able to redirect to a get action and retain the ModelState.

ADO.NET :: ModelState Has An Extra Key Which Is Empty ?
Sep 11, 2010I created a Model to do registration on my Website, and add some validations to it. When the user inputs a data, the data will be checked for validity using ModelState.IsValid. But when I input a correct data, it always be invalid. So I decided to debug my program and found that there are an extra key in my ModelState.
For my model, I have UserName, Email, Password, ConfirmPassword, SecretQuestion and SecretAnswer (6 elements)But when I debug, in ModelState, I found 7 elements, they are UserName, Email, Password, ConfirmPassword, SecretQuestion SecretAnswer and the last one is "".I don't know why there is an extra "" in my ModelState, and I checked that it was the source of my error.
Below I enclose my source to make it clearer
