Web Forms :: Asp Validation Not Working When Browser Security Is High?
Oct 30, 2010
I am trying fire asp validation on page. But it is not working when browser security is high. You can change security setting in IE under tools --> Options --> Security Tab.When i am clicking the button then validation should fired and event shound not fires but if security is high then page is post back and button Click event also fired.Can any one suggest me that how i can handle this problem. I could not handle all the validation on server (Code Behind.).Also Ajax tools also stop working when browser security is high.

Have some problems with client side validation (using RequiredFieldValidator, RegularExpressionValidator, CustomValidator with client side validation logic). It seems that WebForm_DoPostBackWithOptions is not fired or causes unhandled exception that makes the form to do the postback regardless it's valid or not.
I tried using a ValidationSummary, hiding it if javascript is supported:
<script>
$(document).ready(function() {
$("#javascriptDisabled").hide();
[code]...
Every thing works fine on Chrome with disabled javascript on my laptop, but not on my Android phone. The problem is that on the phone Javascript is not disabled, it's enabled, and correctly hides the ValidationSummary, but does not perform client side validation for some reason that i can't understand (no developers tools on Android browser :(( ).This is very frustrating! :(

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.

I have a webform in which asp.net validation controls are implemented.
1. Fill the fields.
2. Press the Save button.
3. Page is validated.
4. If page not validated errors are shown.
5. If page is validated then it post back and the data is saved.
6. After that the Save button is disabled during postback.
7. When user fill the first field the javscript method is called which enable the Save button.
8. Now when I press Save button page is not validated.

I have implemented a validation for the file upload control such that, only when some entry is made in the file upload control textbox, the Upload button will be enabled else it wil be disabled.
When I implemented this , the validation on the Upload button is not working. For the upload button I need to check certain fields are not empty. But I find that because of the above implementation, the validation function for this one is not working .

I have a panel (say, panel1) inside another panel (say, outer-panel)....The panel1 is visible only when a checkbox is checked in the outer-panel. I am using script manager, update panel and trigger to do this.
Now I have many text boxes in the panel1. I have to put a validation on all the boxes.
I tried to test this by putting validation on 2 boxes and this works fine on my local machine. When I put the same logic on the server, it does not. Of course the page on my local machine has fewer text boxes compared to the page on server. But I do not understand why the same logic works on my local machine and does not work on the server.
The page on the sever is a very long one and also it has a captcha control..... when ever I try not to enter text in one the text boxes which has validation and then hit submit...it redirects me to another page with out prompting for the validation error.

We're running a fairly large site, and a lot of our visitors have started using their Android based cellphones to visit the site. However when they try to login, we get an Event Validation error:
Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Does anyone know of a way to fix this, without disabling Event validation entirely ?
It isn't every single time they visit, but it is often enough that it's a problem.
Also we never get these on PC-based browsers (IE, FF, Chrome, Safari, Opera, etc.)
EDIT:
The page this happens on has no updatepanels, no custom __doPostback code, etc. It's pretty much vanilla with a simple LinkButton that causes the postback.
Also this error occurs on a bunch of other pages as well (Just found out about that now), so I doubt it's a lone design fault.

I have a placeholder to which I programmatically add DataGrids... In the DataGrids, I programmatically add TextBoxes along with dynamic validations. Somehow, the DataGrids show up, but the dynamic validations don't work. If I set them to static, the blank space for them appears, but still, they wont work.
