AJAX :: Client Side Validation?

May 31, 2010

I have MaskedEditValidator, which set u pt ovalidate datetime entry into text box. After that the button (html button input control )is pressed in order to start some process. Button is running the client side function (JavaScript).

Now in case of wrong input validator shows proper message, but how I can prevent button to be pressed and start the process. I.e. is it possible to check on client side the status of the validation?

How To By-pass Client-side Validation To Verify Server-side Validation

Mar 1, 2011

I'm interested in identifying a means to verify the server-side validation is performing as expected, but need to bypass the client-side validation being done using ASP.NET validation controls. To test this, I've tried using the form Poster add-on to Firefox that allowed me to get/modify the page contents and post it, but the .NET framework interpreted the submission as harmful and threw an application error ("A potentially dangerous Request.Form value was detected from the client").I've created a WinForm that includes a WebBrowser control and I'm able to manipulate the contents of the web page and invoke the button click, but am interested in seeing how to allow a postback with invalid input values. I don't want to assume the server-side validation works (even though I do check if Page.IsValid on the server on postback).This submits the web form in the WebBrowseer control and the expected client-side validation fires:
extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");
This is how I've manipulated some of the page contents (this just prevents submission):
mshtml.IHTMLDocument2 doc = extendedWebBrowser1.Document.DomDocument as mshtml.IHTMLDocument2;
string html = doc.body.innerHTML;
html.Replace("Page_ValidationActive = false", "Page_ValidationActive = true");
doc.body.innerHTML = html.ToString();
extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");

How To Intercept Or Trigger Client-side Validation Before Ajax Request

Feb 3, 2010

I have a username textbox on a form, that has a few validation rules applied to it via the DataAnnotation attributes:

[Required(ErrorMessage = "FTP login is required")]
[StringLength(15, ErrorMessage = "Must be 15 characters or fewer")]
[RegularExpression(@"[a-zA-Z0-9]*", ErrorMessage = "Alpha-numeric characters only")]
public string FtpLogin { get; set; }

I also have a button next to this text box, that fires off a jQuery ajax request that checks for the existence of the username as follows:

<button onclick="check(this);return false;" id="FtpLoginCheck" name="FtpLoginCheck">Available?</button>

I'm looking for a way of tieing the two together, so that the client-side validation is performed before the call to the "check(this)" in the onclick event.

Edit: To be more clear, I need a way to inspect or trigger the client-side validation result of the textbox, when I click the unrelated button beside it.

Edit: I now have the button JS checking for $("form").validate().invalid, but not displaying the usual validation messages.

Mvc2 Data Annotations Validation (Client Side Works, Server Side Doesnt?

Aug 12, 2010

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?

C# - Show Only Client-side Validation With Client And Server Validators?

Dec 12, 2010

If I have something like the following:

<asp:TextBox id="test" runat="sever"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" ControlToValidate="test"
ErrorMessage="Required"></asp:RequiredFieldValidator>
<asp:Label runat="server" id="lblStatus"></asp:Label>

if in the code behind, I set the label to "You must enter a value if the textbox is empty" to validate it on the server side and this is fine, but if javascript is enabled, I don't want to show the client side validation and the server side label together. Is this something where I would just have to disable the client-side validators if javascript was enabled?

C# - Cannot Get MVC Client Side Validation Working

I have in the fact copied the code of Login page in the ASP.NET MVC application template (provided with VS). In the original template, client side validation is working but when I copy all the connected code I get only server side validation (no red fields, post back even if data are incorrect).

public class LogOnModel {

[Display(Name = "User name")]
public string UserName { get; set; }
[Required]
[DataType(DataType.Password)]
[Display(Name = "Password")]

MVC :: 2 RC On 3.5 SP1 - Client Side Validation From DataAnnotations?

Jan 19, 2010

I have tried everything to get client-side validation to work in MVC2 RC, but have been completely unsuccessful. Server-side validation works just fine, but client-side never fires. I have grabbed

[Code]....

from the futures source, since it wasn't included in RC. Unfortunately, that's the only script that people agree is necessary for everything to work. Besides that, nobody seems to know which other specific js scripts are needed. The candidates are (jquery-1.3.2.js, jquery.validate.js, MicrosoftMvcAjax.js, MicrosoftMvcJQueryValidation.js). I've tried every permutation of these and other scripts to no avail.

Html.EnableClientValidation() has been included before BeginForm, and the JSON validation data appears to be correctly written into the source of the page. But, again, client-side validation never fires.

MVC :: Dynamic Client-Side Validation?

Jun 10, 2010

I have number of fields in the view, which I am dynamically showing/hiding on the client side using jQuery e.g, if user enter 'abc' in first field, I will show three more fields and if he enters 'xyz' then I will show only single field.

I am using data annotations based Asp.Net MVC 2 validation (MVC 2 RTM) and the requirement is that only visible fields should be validated. I have added some code on the server side and the partial validation is working fine there but the issue is on the client side. Actually it works fine first time but fails after wards.

Here is what I am doing:

In $(document).ready event I am popping all the validation stuff in the array as shown below:

for (i = 0; i < numOfFields; i++) {
fValidationArrL[i] = window.mvcClientValidationMetadata[0].Fields.pop();
}

When I show/hide the fields I push only those fields which are visible like this:

window.mvcClientValidationMetadata[0].Fields.push(fValidationArr[i]);

Th I run below two statements to refresh the stuff:

Sys.Application.remove_load(arguments.callee);
Sys.Mvc.FormContext._Application_Load();

It works fine first time but second time when I do show/hide again, it appends the validation list instead of replacing it. So at the end it will validate all the fields that I have shown to the user at some point of time.

MVC :: Client Side Validation For List?

Aug 14, 2010

I have a problem of Validation still present for list object that have been dynamically deleted in the View. Here is the scenario. In my model I have a list. This list can be added and deleted dynamically in create and edit views. Lets say I am in the create view. I add two list objects dynamically and start filing the object and submit the form. The model validation fails in the server side (client side validation cannot be done as it involes some complex logic) because of some errors. Now the errors are being disaplayed for the two objects. Now I delete the first list object dynamically and correct the errors in the second list object and try to submit but the form will not submit because, the client side validation still thinks that the first list object is still present. Is there anyway to remove the client validation for objects that have been removed dynamically ?

My model

Contact.cs:

public class contact{
public List<Address> address;
}

Steps for the problem.

1. Create two addresses in the create view.

2. Fill the fields and click submit.

3. Server side Model validation will report errors for fields.

4. Delete the first Address and correct the errors in the second object and click submit.

5. Submit will not work because the client side validation expects the errors to be corrected in the first Address which has been deleted.

MVC :: 3 Client Side Validation / Regex Bug - Not Consistent

Dec 21, 2010

I have a price field with some simple regex.

@"^(d*(.d{1,4})?)$"
It should allow positive numbers with an optional decimal, and 1-4 digits after.
So values like
2
22
2.2
2.222
.2
.56
0.64

If I use that regex with Regex.IsMatch, it works as I expect. However if use it as a RegularExpressionAttribute data annotation, It will not accept .2, as being valid. It will accept 0.2, and it will 2, 2.22, etc but it will not allow me to lead with a decimal place. I can hack around it by applying a javascript onkeydown event to add a 0 to front if you lead with a decimal.... Am I missing something here? Does the .net double type it backs into not support leading with .2 or is the jquery validation broken or what???

MVC :: RC2 Client-Side Validation Infinite Loop Bug?

Mar 3, 2010

I've found a bug with RC2's client-side validation that causes an infinite loop (at least in IE7).Basically, if you create a standard ASP.NET MVC 2 RC2 web application template and then modify the LogOn.aspx view to this:

[Code]....

Note the new table that has been placed around it.Now, when you fire it up in IE7 and hit "Log On", the whole browser freezes and goes into an infinite loop.I have narrowed this down to the use of OnPropertyChange and the setting of the CSS classes for the elements themselves. It seems whenever an element is in a table, and you change its CSS class, the OnPropertyChange event fires with the property of "value" (which fires the entire process off again hence the endless loop).This is reproducable for me in IE7 (I haven't tested FireFox, IE6 or IE8).

C# - Client-Side Validation In A Modal Popup?

Oct 1, 2010

I've got a gridview/formview, master/detail relationship going on. When I click a button in my formview (item template), I display an ajaxcontroltoolkit modal popup.

On this popup there is a textbox (several, actually). I want to validate the data in this textbox (at least six digits, so far I'm using a regex validator) before I dismiss the popup.

The validator works, but I can still dismiss the form by clicking OK. What I'd like to do is have the ok button on the popup disabled until the data is good.

I have tried fiddling with some stuff in javascript, but I couldn't make it work, as there seems to be some issues regarding finding controls in a formview.
