Is there anyway to do client side validations to work with Devexpress MVC submit button? In my scenario, the normal html submit button will work perfectly without firing the Controller action, but Devexpress button always fire the controller action, means its not actually a client side validation. Thanks
You can try this code:
Buttonsettings.UseSubmitBehavior = false;
Buttonsettings.ClientSideEvents.Click = "function(s ,e) { OnSubmit()}";

I'm trying to figure out how unobtrusive validation works in asp.net mvc 3.
I would like to know what is triggering the validation check when I click to submit the form. How is the script jquery.validate.unobtrusive.js bound to the form submit event ?
I also would like to know how can I manually prevent/trigger this check.
jquery.validate.unobtrusive is a validator for jquery.validate. It is like a extension.
jquery.validate.unobtrusive implements all the events and jquery.validate use it.
You can look into the jQuery.validate.js file and see that it uses the submit of the
form.
// validate the form on submit
this.submit( function( event ) {
...
If you want to trigger the validation by yourself you can call
$("#myform").valid()
I am fairly new to .NET and MVC3 - and even Ajax and Json, and am working on an MVC3 (razor) application, using jqGrid, and so far it is immense(jqgrid that is!) and has dealt with everything I have thrown at it.
However, I have One Outstanding peice of functionality that I do not know How to accomplish.
Within the Edit form of a Row, I have Placed a Custom button called 'Reset Password'. I need the Onclick Event to call a piece of functionality in my Controller to go through some logic, generate a Password, and Return the new Password to the Screen.
Can anyone tell me How can I achieve this?
May thanks in Advance.
You can return a partial view result or json data from the action.
See the partial view approach here
I'm familiar with the method of submitting a form via a change event like or a checkbox's check event. Most articles explain how to find the first form using jQuery and invoke it's submit() method. However, I wish to submit the form but not cause validation so the back-end can perform other actions. In my case, I have a dropdown that a users changes. Depending on the value, the back-end adds/removes certain controls. The issue I'm runing into is that the validation prevents the form from submitting.
Q: How do I submit the form so it does not perform client-side validation?
Remove the validation just before the form is submitted - check out the answers here How do I remove jQuery validation from a form?
I think you can just turn the validation off by calling #Html.EnableClientValidation(false)
How Can I Return or open a view in new window browser from only controller code when some validation a true But Not from Links and button code it should open automatically modelstate if is valid.
Thanks...
My guess at what you are trying to do is have the browser pop up a window once the form is correctly validated. The way I would do this is to have a javascript function that is validating the form and once it is valid then pop up the new window.
If you want the validation to occur on the server side you could use AJAX to post the current form values back to the server and have it return the validation.
How do I start validation from the client/javascript using the MS MVC Validation library?
Using MS ASP.Net MVC, I have a page with a PartialView in a modal dialog (change password). When the user selects 'save', I need to validate this on the client side without a full page postback. I am able in JS to post and refresh the partialView, however I am unable to start client validation. The MS MVC validation starts on postback (Input type='submit'). How can I start this in JS?
Validation on the full page with postback works. Thanks,

I originally posted a link to ASP.NET MVC 2 Custom Validation but I realized that I missed part of the question... It does appear that a few insights are present in the post titled Combining JQuery Form Validation and Ajax Submission with ASP.NET.
