I have this code in my view page.
<td>
Mandate Name:
</td>
<td>
<%= Html.TextBox("MandateName")%>
</td>
I wrote MVC2 Validation for this name.
something like this.
//[Validator(typeof(MandateValidator))]
[MetadataType(typeof(Mandate_Metadata))]
public partial class Mandate {
public class Mandate_Metadata
{.........
I am using MVC 2 with Entity Framework 4 models and MetadataType classes to create annotations that do not vanish everytime my model is generated... I followed Scott's article to create that.It worked fine for simple classes, but when I got to a more complex one, with regular expression and range validations on doubles, it seemed to simply ignore the validation annotations altogether.

View 3 Replieslink to Implement ASP.net mVC2 validation for my dropdown list boxes in my view?My Dropdown listbox in my view is something like this

I am trying to make some sense of this validation stuff in MVC2. I followed various walkthroughs, all them for betas/rcs... and I cant' get anythign to happen. Note: THIS JQUERY - NOT THE MS AJAX STUFF!I have referenced MicrosoftMvcJQueryValidation.js which i got got the mvc2 futures lib.
My model is:
[Code]....
The form bit of my ViewPage<User>:
[Code]....
As far as I can see the only additional thing that is being rendered is this:
[Code]....
Which is interesting/annoying for a few reasons. Firstly all of my annotations appear to have been ignored.Secondly FormId isn't even marked as required, and as this rendered text was taken from a page loaded with a null Model (add mode) the FormId field isn't in the form. Finally, this doesn't even result in any actual validation occuring (on the client side). All the server side validation is working fine.See I am using PasswordFor instead of EditorFor. Because someone at MS testing dropped the ball there. Yes EditorFor renders a password field, but it behaves differently to PasswordFor.. the value of the Password field is sent to the client (set in the value
attribute of the field). Fail.
I've got a custom Editor Template that is essentially:
<div id="control">
<%: Html.DropDownListFor(model => model.Day, Model.Days)%>
<%: Html.DropDownListFor(model => model.Month, Model.Months)%>
<%: Html.DropDownListFor(model => model.Year, Model.Years)%>
</div>
Whilst my validation is successful/fine with this control (ValidationMessageFor works) I have been unable to find how to highlight the control when validation fails (e.g. with a TextBoxFor the textbox border goes red if validation fails)
Does anyone know how I can add this behaviour with a custom editor template?
I'm attempting to write a unit tests for an ASP.NET MVC 2 post action that takes a view model as its sole parameter. The view model is decorated with validation attributes such as [Required]. I'd like to test two scenarios. The first scenario is when a valid set of data is passed in (ie, all required properties have values) and a redirect to the list page is returned. The second scenario involves passing in invalid data (eg, when one or more of the Required properties are not set). In this case the same view is returned with error messages.The action signature is as follows:
[HttpPost]
public virtual ActionResult Create(NewsViewModel model)
The NewsViewModel class is as follows:
public class NewsViewModel
{
public Guid Id { get; set; }
[code]...
I'm using an entity model with metadata annotations. My controller method looks like this...
if (!ModelState.IsValid)
{
return View(model);
}
else
{
UpdateModel(model);
repo.Save();
return RedirectToAction("Index");
}
If I enable client side validation in the view I'll get the error per the Attributes from the metadata class. If I take clientside validation out, error gets thrown from saving to the DB rather than return the view with an Error Summary.
This is the top portion of my view....
<% using (Html.BeginForm())
{%>
<%: Html.ValidationSummary(true) %>
I've tried running without debugging (ctrl + f5) in debug and release mode as well as setting breakpoints and Debugging (f5) but it just seems weird to get Client side validation without server side validation. What am I missing here?

View 1 RepliesSuppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?
I am reading in a file into a string. Then I am writing this string to a stream. I know this code works fine.
The only problem that I have is with the line that write the data in chunks where the parameters is not supported for the Write method.
The line that has the problem is this line. What do I need to change here?
OutPut.Write(buffer, 0, Math.Min(to_write, WRITE_CHUNK));

View 3 RepliesI want to write a page where user's can write a blog post and publish it to the blog. I've downloaded blog engine .NET and looked at the code and I like the way they do it, but it's completely an overkill of what I need. What I need is only a title, author, date, and the blog post it self. I don't even want users to post comments or anything like that. My approach is to save all those blog post information into an xml and then when a page loads it loops around those xml files to show the blog post.

View 10 RepliesI am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?

jQuery validation is working fine on my machine, when i pushed it to test server it won't it's throwing some errors which is kind of surprising.These are the errors I am getting: $.validator is null or not an object...I've never gotten this error before and it throwing an error when I declared a variable like var isValid.I don't know what to do. I am doing the custom validation methods not in the document.ready(). Does this cause this error? I wonder because all jquery validations are passing and hitting the server side validations.
