Something is wrong in ASP.NET MVC 2 on client side validation. If I have form for create records in database and all fields are required, validation is triggered only then when I write something in field and delete it. If I go to field, stay this field empty and press Tab key validation isn't triggered.
Here somebody else write about the same problem: [URL]
Here is the code I have so far:
[code]....
When I click submit, It does the validation on the server side, I kinda like it to validate on the Client instead of taking a trip to the server right away.
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've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked. I've been used some code I found on dotnetjunkies.com but the client-side validation didn't work. I've been attempting to modify it to get the client-side javascript validation to work with no luck. Basically, I compile the below code into a DLL and add it to my bin folder.
[Code]....
I am trying to see the validation part working. I have few required field validators and compare field validators, etc.
<div>
<asp:RequiredFieldValidator ID="rfvCompany" ValidationGroup="groupProfile"
ControlToValidate="txtCompany" runat="server"
ErrorMessage="- Company Name Required" Display="Dynamic" />
</div>

my question is very simple. I had read through many post include this: http://blog.anasghanem.com/post/How-to-get-the-readonly-textbox-value-on-the-server-.aspxI have a calender extender and the date was target to a texbox. This textbox, i had set it to readonly and it is validate by a required field validator. so mean this texbox must have a value inside. my prob is, i bind the textbox to database and if data is NULL or empty i can't save it because the required field validator was validate textbox as empty value at cllient side. If i remove the required field validator everthing fine. But this is not i want. I have try to set the textbox to javascript onCopy,onPaste,onkeyup. but user also can delete and paste into the textbox.i have think to disable the requried field validtor at server side when data is inserted.
View 16 RepliesIn my web page I have a Checkbox (datatype = tinyint/boolean) and 2 Required field validator (whose visibility is false). I want that when I check(tick) the checkbox, then required field validator visible = true, else not.For this I tried this code on Page_Load as well as on save button click, but it is not working:
protected void Page_Load(object sender, EventArgs e) {
if (ChkComplexPass.Checked) {
Regex4.Visible = true;
Regex.Visible = true;

In my view data class I have a List.

I have all the properties of the class Person as required using Data Annotations.

In the View I loop the List like this:

Does not work at all.

Tried using these HTML Helper methods instead:

Interestingly, when I trigger a validation on the first textbox, it fires simultaneously for all of the textboxes. The rest of the textboxes do not trigger validation at all.
Looking at the generated id and names for the textboxes and their corresponding error text span element, they areall identical.
Anyone figure out how to use Client Validation with Data Annotations with a List in the view data,
supporting Model Binding?
I have this compare validator:
<asp:CompareValidator ID="cpvBirthDate" Type="Date" ControlToValidate="txtBirthDate" Operator="DataTypeCheck" runat="server" ErrorMessage="Please enter a valid date in this format mm-dd-yy">
<img src="Images/ExclamationMark.gif" alt="Please enter a valid date in this format mm-dd-yy" />
</asp:CompareValidator>
It works on the clientside fine, but if a user has javascript disabled then it accepts 071873 which is not a date. Do I need to write a specific serverside function for this validator to work?
I am using compare validatore for comparing two date ie. from and To date
i am using it rightly even i tested on vs 2010 it working fine ,
bt i upload the project or my website on client side or host in iis server
i get the error msg
compare validatore not working on client side
even i use the culture gb-usa
I've been working on a task to add a validator to compare the values of two text fields in a ASP.NET 1.1 application.
It uses validators already, so the best approached seemed to involve a CustomValidator. I was inspired by the following example:
[URL]
I got the server side validation working - now I'm trying to add some client-side validation but I'm having a strange issue.
When I click in either of the two text fields, the value of the txtFinalGrade field is overridden to either "true" or "false". I've been having a tough time tracking down the code that's causing this. I tried using the IE Developer Toolbar to trace the script - as well as FireBug in Firefox (though this is an IE-only app) and I'm still trying to figure out what's causing this to happen.
Since I think this is a JavaScript issue, I'm posting that part of my code:
[Code]....
Anyone have ideas of things to try? Anyone have similar issues with textboxes being set to true/false when working with custom validators?
I have a validator on a textbox that validates against a list to ensure that the user doesn't input the same name. When testing it, if I type in the same name including the same case structure, it returns an error. If I change one letter to a different case, it doesn't return an error but rather my SQL server returns a duplicate error. How do I change the server-side validator so that it picks up duplicate names regardless of case?
View 4 RepliesWhen it comes to field validation, when I use a Compare Validator to make sure a date is a date or a numeric field has a number, I must also use a Required Field Validator to make sure there is something actually enetered. In other words, the Compare Validator allows a blank value even though a blank is not a date or number or whatever.
Is using both a Required Field Validator and a Compare Validator the way to do this or is there some way to make the Compare Validator also require input of some kind?
Using MVC 3 RTM and MvcContrib/FluentHtml version 3.0.51.0, I can't get the jQuery client side validation to work. Server side validation works fine, and returns showing the correct validation summary, etc. But the form post always tries to hit the server-side post controller action when it should have stopped on the client side to display the validation error.
I tried replacing the MvcContrib ModelViewPage with the default Mvc ViewPage and it still didn't work.
Here's my code:
Web.config has:

In my project, In gridview i want to add a client-side confirtmation for deleting a record. Everything seems right, browser asks for confirmation, after pressing "yes", nothing happens in gridview as well at database. What's the missing point ? Also in gridview, after pressing edit button "ArgumentOutOfRangeException was unhandled by user code" exception occurs

I have a page where i have the products names and their prices displayed using a repeater control. The sum of prices appears in the footer using a label. Each detail row has a checkbox, which can be checked unchecked to see the total sum of prices.
I have already done this using javascript.
My question is ,
"is there any better way like using any AJAX control to do this ? or this is the only way to do it without posting back to the server?"
I have studied Phil Haack's post [URL]about custom validation, however, I can not get this to work for my case. I need something like the "PropertiesMustMatch" validator in a default MVC2 project generated by Visual Studio.
None of my custom javascript gets called. I am registering the custom adapter in Application_Start using DataAnnotationsModelValidatorProvider.RegisterAdapter(....). In the DataAnnotationsModelValidator derived class, GetClientValidationRuls is never even called.
What is going on here? Maybe this type of validation where your validation attribute has to be applied to a class, not a propety, does not yet work with the RTM release of Visual Studio 2010.
I have a gridview on my aspx page having templatefields. In one of my templatefield i have a textbox with requiredfieldvalidator for validating input in textbox.

I m trying like this-My aspx code-

I have a text box in which I want only digits (either decimal or whole numbers). I have applied Required Field Validator and Regular Expression Validator on it.I have an Image Button, by clicking on which, I want this validation to be performed. But when I build the code, and clicks on Image Button, these validators do not work and I am redirected to the server side method of Image Button and after completing the execution of server side method, control comes to these validators and client side validation executes.I am fed up by finding solutions on Google and unable to find any solution.Please tell me of anyone of you know the solution that why server side code is running first and client side validation is executing after server side code execution.

The problem is, when I click the button it shows a '*' in front of every textbox in odd or even items, instead of validating only the textbox in that item.
How can I validate only the text box inside the item in which the button being clicked resides?
in my module there are data of students for H.S.C., C.E.T, AND H.S.C+C.E.T. so when i run the gridview page all the data of all streams together is displayed so i sort the data using a dropdownlist...means if 1 select the H.S.C in dropdownlist only the H.S.C students are being displayed.so the problem is when i sort the data by selecting a stream in dropdownlist at that time the error message of required field validator is displayed...
1) I wil select the stream from Dropdownlist and click the "sort button"
2) After the data is been sorted and i will enter the values in   the TextBox and if i'll miss any of the textbox blank and i click on the "submit button" after dat the error should be displayed
as "Required".

in my website there is a module in which i m fetching the data of present students in the gridview and i m entering there marks in the gridview textbox column (created by using item template)...I want to add required field validation to the textbox columns so that after clicking the submit button there should be an error message displayed if any of the textbox is empty...
View 1 RepliesI'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())

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?
