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.

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:
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();

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);
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"
<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?

AJAX :: Modal Popup Dialog Validation?

Mar 23, 2010

I have a button Import on my page. Upon pressing this button, a modal popup dialog appears where the user can enter path of the import file. I have a required field validator to make sure the user entered the path. And I have there a Submit button. My problem is that validation happens not only when I press the Submit button on the modal popup, but also when I press any button on the page itself, which is wrong.

AJAX :: Validation Summary In JQuery Dialog Modal Popup Box Not Working With Update Panel

Dec 23, 2015

I'm using the ASP.Net Validation controls and I want to display the Validation Summary in a JQuery Dialog instead of the native javascript alert messagebox. I've found this solution (aspsnippets) by overriding the clientside WebForm_OnSubmit() function:

<script type="text/javascript">
function WebForm_OnSubmit() {
if (typeof (ValidatorOnSubmit) == "function" && ValidatorOnSubmit() == false) {
title: "Validation Error!",
modal: true,
resizable: false,

[Code] ....

The WebForm_OnSubmit() function is being rendered by the BaseValidator control and in the form tag te following attribute is being added: onsubmit="javascript:return WebForm_OnSubmit();

I am running into a problem on a page which has an UpdatePanel. The input field with the validator (1 to make it simple) is in a Panel within an UpdatePanel. The Panel is set to Visible=False at the first Page Load. There's a button inside the UpdatePanel which makes the Panel with the Validator Visible.

When this happens, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered because it's an AJAX callback and the form tag is outside the updatepanel (in a master page), so the validation summary will not be shown in the jquery dialog.

Validation is being performed, so the validation summary wil be shown in a div on a page, but the validation is not being called by the WebForm_OnSubmit() function in this case, because it's not being rendered.

Here's the markup of the page:

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<asp:Button ID="btnNew" runat="server" Text="New" />
<asp:Panel ID="pnlEdit" runat="server">

[Code] ....

So, when the validators are not visible at the first load and they will be made visible by an AJAX callback, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered on the pag. Because of that, the WebForm_OnSubmit() function will not be called and the validation summary will not be shown in the JQuery dialog (although it is being shown in a div on the page). How can I get the Validation Summary to be shown in de JQuery dialog in this case?

Is there another function that has to be overriden for this case? I know I can use a Full Postback for the New button and then all the stuff needed is being rendered on the page, or I can make the panel not visible by using a style, but I don't prefer that because there are a lot of pages with this situation.

One solution is to use a dummy textbox with a dummy validator (with a dummy validationgroup) of which I set the display to none. Then this dummy validator will cause the the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag to be rendered.

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; }
[Display(Name = "Password")]
public string Password { get; set; }

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


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:


Th I run below two statements to refresh the stuff:


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?
