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.
my page has two part.one part for inserting room information and anothe part is for inserting apartment information.foreach part i have some validations.i want when click in roominsert button validation in apartment part disable.
I have a simple problem: I have a bunch of controls on a page and each one requires a validation. Also, I set control's enable=true/false programmaticaly, based on a checkbox . Now, I would like to disable the validation of a control if it is not enabled.
I have orders page. When user submit Order, I need to disable the button to avoid multiple transactions. I also have few validation controls on the page, so button should not be disabled untill page is about to be posted. I dont have any custom javascript for validation. It is just these asp.net validation controls. What is the best way to achieve that? I have spend about 2 hours on google and found various solutions, but nothing seems to work. Each has some issue. On button I add OnClientClick="return btnOnClick this, 'Payment');" Below is what gets called. Unfortunately if I disable button, it cancels post back. So I am calling dopostback and also adding few lines on server side to see which button caused postback. It works fine in IE8 and Chrome. But for Firefox on server side arg comes null. Any ideas what is wrong with my code? Or any other suggestions to do it in a better way?
C# Server side string arg = this.Request.Params.Get("__EVENTTARGET"); if (arg == "Payment") { this.ProcessPayment(); } Button <asp:Button ID="btnSubmitPO" OnClientClick="return btnOnClick(this, 'Payment');" runat="server" Text="Submit Order" ValidationGroup="G" /> alert(group);
I having a two radio button. When the second radio button is enabled, a text box which accept the email id will appear. I am validating the Email using Regular expression validator.
When the second radio button is clicked, and I enter the invalid email id so that it shows me and error. But when I click the first radio button, it is showing the save validation. I need this to not show the validation when the first radio button is clicked and invalid email id is there in the text box.
I want DefaultModelBinder not to perform any validation based on DataAnnotations metadata. I'm already using DataAnnotations with DynamicData for the admin area of my site, and I need a different set of validation rules for the MVC based front-end. I'm decorating my classes with the MetadataType attribute. If I could have different MetadataType classes for the same model but used on different scenarios that would be great.If not I'm fine with just disabling the validation on the DefaultModelBinder, either by setting some property or by creating a specialized version of it.
I'd like to disable ModelState validation messages and keep my data annotation error messages.
When I update model, message "The value '' is invalid." apears in ModelState. I know that I'm trying to assign null to not nullable property, but I have my own validation and message.
I use something like this
[Required(ErrorMessage="Blahblah some error")]
I want user to see my message "Blahblah some error", but not stupid message: The value '' is invalid.
In this field I have a RequiredFieldValidator validation only. Unfortunately, after any PostBack if the content of any of the fields includes HTML tags or any other potentially dangerous code - the entire ViewState is cleaned.Setting ValidateRequest to false does not help. I'm using IIS 7.5 and .NET 4.0.
I would like to disable all client side validation in an Asp.Net web site in order to test that server side validation is correct (i.e. I want to test against people altering the response or tampering with client script)Currently, I am either-Disabling JS in the browserManually disabling client validation for individual validators.
I have an asp.net application that uses validation controls on textboxes. However, if the user enters a value in txtFieldA, then I want to disable the validation controls on txtFieldB and txtFieldC.
I have a div where I put a lot of stuff on runtime to construct a chart. The user should be able to copy the chart to another div (innerHTML) and then make som adjustments to the original div, which causes a postback. Of cours the cloned div comes back empty.
So I'm thinking of putting the entire innerHTML in a session variable at page_unload, but then I run into the validation problem. I've tried using a hiddenfield as an in-between control, but it's the same, and it seems you can't use the CausesValidation on that control. I've also tried a regular asp:textbox, but the CausesValidation doesn't have any effect.
How to do this? Or any better way all together on the copy-chart issue?
I have a form that occassionally submits more than once per user. I am assuming the problem is that the user gets impatient and clicks submit multiple times. I have a bunch of asp validation controls on the page. There is multiple validation groups, the submit button belongs to the "main" group. How do I validate the "main" group, then if the page is valid, disable the button and submit it? I tried adding this.disabled=true; but that just disables it and doesnt submit or anything.
I am using xVal in a ASP.NET MVC project. One of the forms has two buttons and i want to disable the client side validation when one of the buttons is clicked. Is there a way to conditionally disable client side validation in xVal?
How can I conditionally disable client-side validation of some fields ?
Here is the example of what I need to do:
user writes name and address and submits. Both are validated both server and client side. If validation passes e-mail is send to given address and (name, address) pair is stored.as a response same page is displayed (I don't want redirect!) this time with confirmation. User can retype their name and submit. In such case e-mail will be resend to the address that corresponds to given name.
It does not work because: client side validation will not pass when user clicks resent button on the second (confirmation screen). It would say that e-mail is required even if there is no field for it. How can I disable javascript validating email before the confirm page gets send to user ?
Example ASP.NET MVC page
<%if (Model.Confirm == false){ %> <% using (Html.BeginForm()) { %> Your email: <%: Html.EditorFor(m => m.Email) %> Your name: <%: Html.EditorFor(m => m.Name) %> <input type="submit" value="Send Email" />
I am creating a fairly straight forward form for collecting data about vendors. I have a requirement that says the email address is required for a certain payment method and not other payment methods. The way I currently have this implemented is using a dropdownlist for the payment method and a TextBox for the email. I have been using ValidatorCalloutExtenders on all the other input fields with great success, but this is the first case where I need to be able to turn the validator and extender behavior on and off based on a selection of the dropdownlist.
I have tried many things and have searched these forums and google until my hands and eyes got tired, but have yet to find success, hence this post. I am aware of the dispose and $create methods, and that is currently what I am trying to do, but after the create occurs, while the behavior has been created, it doesn't seem like it has been created completely or something. To implement this, I am using a function tied to the onChange Event Handler of the drop down list. The function essentially checks the dropdownlist selection value and if it is NOT "ACH", then it finds the behavior attached to the requiredfieldvalidator attached to the email textbox and calls the dispose method on that behavior, if the selection value IS "ACH" then the method calls
The reason I say this, is because once the page loads, the default value is to have the validator disabled, then if I select the payment method that enables the validator, it seems to work fine, but then if I cycle through the payment method choices again, I end up with a null pointer exception to the TextBox element when the validator is trying to apply the highlightCssClass on form validation. So, to summarize, it seems like when the page loads, things get built correctly, but then when I start doing the dispose and $create, things are recreated correctly so that when the submit button click causes validation, the validator throws a null pointer exception.
I know it can be hard to debug this sort of thing using words, but I was just wondering if I am going about this the right way or if there is an easier way to conditionally enable/disable a requiredfieldvalidator and validatorcalloutextender.

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
