I was using RangeValidator to validate user input on client side for double values.One of my user said that when he enters 5E-10, my range validator does not understand that number as a valid double.

How do I implement client side validation for input fields that have been added to the form dynamically with javascript in an MVC 2 application?
View 2 Replieswant to know that can we validate a control which is out side a form element in asp.net(server side validation)and outside a form element in html(client side validation) let's take a closer look
<html>
<body>
<input type="text" name="first name"/>
</body>
</html>
can we apply clien side validation on above text box by java script ?in asp.net
<form runat="server">
</form>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
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");
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
I am using below code to validate interger and float in asp.net but if i not enter decimal than it give me error
<asp:TextBox ID="txtAjaxFloat" runat="server" />
<cc1:FilteredTextBoxExtender ID="FilteredTextBoxExtender1" TargetControlID="txtAjaxFloat" FilterType="Custom, numbers" ValidChars="." runat="server" />
i have this regex also but its giving validation error if i enters only one value after decimal. [URL]
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?
I am trying to create a custom password validation attribute which has these requirements
1. cannot be empty.
2. doesn't contain space or other special chracters, which I'll define later.
3. length is between 6 - 12

it works fine on the server-side but I'd like to make this work on the client side as well, so I created a PasswordAttributeAdapter class

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?
I'd like to implement ajax message box that will gather information from validators on a page when client-side validation fires. Like: I have left some text fields blank then press submit button and appropriate RequiredFieldValidators show messages. I would like my message box shows those messages too. I am looking for appropriate way to hook on validators JS event or something.
View 2 RepliesI am using ASP.NET MVC2 and to validate the forms i use xVal. It seems like the server side validation works fine, but the client side validation doesnt work or atleast doesn't show up.
The code i use looks like this:
<% using (Html.BeginForm()) {%>
div class="label"><label for="EmailAddress">Email Address</label></div>
<div class="field">
<%= Html.TextBox(Prefix + ".EmailAddress")%>
<%= Html.ValidationMessage(Prefix + ".EmailAddress")%>
</div>
<%}%>
<%= Html.ClientSideValidation<Customer>(Prefix)%>
When i remove the prefix it works fine. But when i remove it only the server side validation works.
Searching on xVal on this side i found this post that looks a bit like the same problem: [URL]
I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?

I use the oob client side validation from mvc 2 RC. The input field validation errors are working fine. But the validation summary is missing. How to get the validation summary on client side validation?
View 3 RepliesWhen i use Validator callout extender and as well both client side java script validation , both are not working at a same time.I use java script code for dynamic checkboxes to be atleast one checkbox must be checked.When i use onclient click only javascript validations are fired, when use onclick function javascript code is not working.
View 7 Repliesthere I am using xval for the first time, it seems to work fine for required fields, However I am having some issues first of all it does not seem to validate booleans and also client validation is not working for me, this is not a major issue for me, the one that I really need to work is the stringlength property. It seems to do something because the form is not posted when the string length is exceeded, however no error message is displayed to the user which is obviously not what I want, has anyone been able to do this successfully?
My model goes like this

I need to validate two textboxes for date range in client side. what is the best approach ?

View 2 RepliesI 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 {
[Required]
[Display(Name = "User name")]
public string UserName { get; set; }

[DataType(DataType.Password)]
[Display(Name = "Password")]

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.
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.
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?
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.
