I am trying to design a page that has two radio button options and two text boxes with each radio button. I am validating these text boxes using data annotation validation attribute.
I am using jquery slider.toggle() to display each text boxes according to the radio button clicked. When i submit the page, required field validators of both text boxes are triggered. What I want to do is to disable the first text box validation when the second radio button is clicked.
Is there any method in MVC to disable the validation of text boxes when the radio button associated to it is not selected?
This can be done rather simply front end. The validation which occurs is done based on html5's data attribute. Remove the data attributes from an input element and the validation will cease to function.

I have a wicket page with a couple of TextFields that have different kind of validators. So far, validation is triggered via Ajax on the onChange event.
I also have a checkbox that defines which set of validation rules should be used for the TextFields.
If I click the checkbox and then input data into the TextFields, validation works just fine. But how do I handle the fact that already entered and validated data can suddenly become invalid if the checkbox is clicked afterwards? How do I trigger the validation and the redraw (to show the error notification) of the TextFields from within an AjaxEvent from the checkbox?
I tried to call myTextField.validate() but that didn't trigger any of my validators.
Since your validation is based on multiple components you should implement IFormValidator. Pass both checkbox and textfield in getDependentFormComponents() and change of either will trigger it.
Also if you are using checkbox to refresh some elements make sure to use AjaxCheckbox, that has onUpdate(AjaxRequestTarget) method.
You could attach an AjaxFormSubmitBehavior in the checkbox. This would submit the form and trigger validation each time the checkbox value is toggled.
I have added dynamically some radio buttons to a jsp page.
Now i need to use the unique id of the selected radio button,pass it to some other servlet to process it?
How can it be done?
Place all of your radio buttons within a form that submits to your servlet. Make sure that each of your radio buttons name attributes is set to the same value. Also set the value attribute of each radio button to its respective id. When your form submits, it will pass the value of the selected radio button to the servlet. You can then retrieve the value using request.getParameter().

Can someone help me with this line of code and tell me what it is looking for? This chunk of code is associated with a text box control on my page.
ValidationGroup="<%# ((TSAPassenger)((RepeaterItem) Container.Parent.Parent).DataItem).PaxKey %>" runat="server" ErrorMessage="Invalid Contact Name.">
When a postback occurs (via a button press, autopostback dropdown list, etc), ASP.NET will validate all inputs for the validation group specified on the control that caused the postback.
That line of code is grabbing the 'PaxKey' property of the data item for the repeater item two levels up in the control tree that contains the text box and using it to specify the validation group the textbox belongs to. This is likely there to limit the validation to just the fields for the record you're updating (as opposed to everything on the page).
I am creating an MVC3 website and added a couple of security questions to the "My MVC Application" Registration routine in the form of dropdown boxes. I created a custom validator to check the second dropdown box and if the selected item is the same as the first then it shows an error message.
My problem is that the clientside validation triggers as soon as the second dropdown box loses focus. After the error is displayed, ideally, I should be able to change the selection in the first dropdown box and the validation error message for the second dropdown box should go away. But, of course, changing the first dropdown box does not trigger the clientside validation routine for the second dropdown box and the error does not go away.
I would appreciate it if someone who is well versed with the internalls of unobstrosive Ajax validation routines would guide me to a solution so that when the selection of one dropdown box changes the validation routine of both dropdown boxes is triggered.
Thanks a bunch for any pointers.
If you look at this question and my answer, you will see code for client-side validation where changing one field will trigger validation on another field, and will then stop after both fields' validation has run.
I am using Silverlight + MVVM to host a form with some fields like drop down list, text boxes and date controls.
I have some validations on the textbox and date control which fire automatically when the control loses focus.
I wanted to know if there is a way to reset the validations based on the drop down list change (captured in View Model)?
