Is there a way to trigger the validation on the form on the first load? my form loads its data from the DB and the data could already be partially filled by the user - so i want to run the validation on the first load to show the user what he needs to fill and how muchi failed to mention it earlier - i need to perform the validation on the server side - not client side (all the validators i use have server side validation code as well) - and my attempts to call:
Page.Validate();
Page.Validate("My Validation Group");
both resulted in
Page.IsValid == true;
the full scenario is like this:i have a very long form that stretch over several pages - the user is allowed to move between them and fill in the information - without validation getting in his way
then when he finish he clicks on a different button (that exists on all pages) and that page needs to validate the entire form - and if there is a problem jump the user to where the problem is - i coded all the validation checks into asp.net validation controls - and i whuld like to trigger those controls even if the user jumps to that page by pressing the validate button on a different page - the problem is that the move to that page is regarded as a NEW load of that page (in fact it is - and hence the validation fails to work)
Is there a way to not trigger the validation until a checkbox on the form is checked? We have a form that a user does some work in, so they could be adding data throughout the day and saving it, but when it is complete and they check the completed box I want it to run the validation.
I am using Update Panel in my asp page and I am doing JQuery Validation on Asynchronous Postback...I just want to validate my form on only button clicks or submits..My problem is..all my buttons are in different formviews and won't load at a time...that's why I am unable to take the button id's and use the click events..here is my code..
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(ValidateMyForm); function ValidateMyForm(sender, args) { var objPost = args.get_postBackElement(); [code]..
All I want to do is: 2nd time validation on only button submit not for everything...I do get other postbacks on this page and those post backs also gets validated each time (I want to Avoid this)...
Is there anyway to trigger the ValidationSummary before the user hits a button that causes validation?I have a bunch of text boxes with Required and Rregex validators attached, as I type in them and tab out they trigger their errors however the summary doesn't show anything until I hit the Submit button. Any way to have the ValidationSummary update itself in the same way as all other validators?
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.
I have a Asp:modal (AJAX) that works fine on a master.page
When i then add an asp:menu with sitemapdatasource, then the page works fine first time at page load, but if i then click the btn that trigger the asp:modal i get this error
[URL] ....
What I want is that the user can write an email in a textbox on the masterpage and then hit a btn, if the email is valid 100% the event is trigged and the asp:modal is showed, its works fine when i dont have a asp:menu on the masterpage, but when i then add the menu, then the pages works, but when i will trigger the asp:modal then i get the error.
I have required validation controls on a page. If the user got to this page by mistake and wants to go to a different section of the website using the navigational buttons; required validators are triggered and it will not let the user navigate away. Ho do I get validators to trigger only when a submit button is clicked?
I've searched around a lot, and honed this problem down to this case: I'm using the PRG pattern, pragmatically I'm using the same DTO for my post/get actions. It looks like when I have the dto with the data annotation attributes in the get action parameter list, the validation is always displaying errors, every time on initial page load. In some cases this could be desired behavior if you put asterisks in the error message, but how do I get rid of it?
I then use .RenderControl on both rblQuestion and rfvQuestion, concatenate into a string then use the HTML String to populate a PlaceHolder.
This seems to work fine, all appears as expected apart from the RequiredFieldValidator - I get a red asterix (My ErrorMessage) next to each RadioButtonList - But this appears as soon as the page loads, not on a post/button click.
To this Redirect.aspx page, I'm directed from some external page. In the request context, I have APP_ID key, which is passed from this external page. Next, I want to pass this APP_ID value using POST to some other page, which is defined in the configuration. Unfortunately, I'm getting such error while redirecting:
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
I don't want to disable view state validation (<pages enableViewStateMac="false">) because this is not the "solution" I want to apply.
Besides I don't understand why I'm getting such an error. Can someone get me through this ? Is there any other way to automatically submit a form on Page_Load event ?
I have a async file upload control and I am doing client side validation for Image."OnClientuploadstarted" I am doing the client side validation.My validation is working fine but my problem is that the file upload control text box goes green (i.e file is loaded on the server) even if the validation fails which is I dont want.What I want is when the client side validation fails the file does not gets loaded on the server and the Async file upload textbox does not goes green.I have goggled but have not found a suitable solution.

But when I have a ListView or DataView, etc... with a pager, I get problems when I click on 'next page'.Then I get the error: Validation of viewstate MAC failed. When I don't use Jquery's load function, I don't get an error.

I am migrating my application to MVC3 and getting this error message Validation parameter names in unobtrusive client validation rules must start with a lowercase letter and consist of only lowercase letters or digits.How can I ovoid it without going and modifying all my ViewModels
I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?
I am creating dropdown controls in code behind. in some conditions I need to add validation control to dropdowlist. But Validation not firing when I submit button.
If mQuestion.RequiredToAnswer = True Then Dim mValidator As New RequiredFieldValidator mValidator.ControlToValidate = mDDL.ID mValidator.InitialValue = mDDL.Items(0).Text mValidator.Display = ValidatorDisplay.Dynamic mValidator.ErrorMessage = "* Required!" mTableCell.Controls.Add(mValidator) End If
I have other dropdown controls on aspx page with validation comtrols. Those are working fine. Only when I ddl and validations from code not working?
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.
How can I disable the code behind validation when javascript validation is present? Then if there is no javascript enabled then the code behind validation will do its thing. What I notice is that it's reading the code behind valdiation not the javascript.
