Using ASP.NET AJAX PageMethods and Validators

Question

I have a basic CRUD form that uses PageMethods to update the user details, however the Validators don't fire off, I think I need to manually initialize the validators and check whether the validation has passed in my javascript save method. Any ideas on how to do this?

Answer 1

Ok so I finally solved this: You need to call Page_ClientValidate() in your Save javascript method and If it returns true continue with the save, the Page_ClientValidate() initiates the client side validators, See code below:

    function Save()
    {
        var clientValidationPassed =Page_ClientValidate();
        if(clientValidationPassed)
        {
            //Save Data
            PageMethods.SaveUser(UserName,Role,SaveCustomerRequestComplete, RequestError);
            $find('editPopupExtender').hide();
        }
        else
        {
            //Do Nothing as CLient Validation messages are now displayed
        }
        return false;
    }

what are you using for development? VS 2008 supposedly has better JS debugging, haven't tried it yet.

For Ajax you can use the Sys.Debug obj

If you use Firefox, you can use the FireBug plugin. It has great javascript debugging support.
