I posted the following question on
StackOverflow, but got no response.
So I will try here:
I am attempting to use KendoUI Validator with an ASP.NET WebForms project. I have a simple page, that has a number of inputs, and of course ASP.NET adds some hidden form elements as well.
I have the following questions:
- Why does the KendoUI Validator not ignore hidden form fields, and how to I get it to?
- Why does KendoUI apply the rules to every input field, and how to do get it to ignore some fields. I want a declarative way to do this, not by adding all sorts of exceptions in my validation rule, as per the example in the KendoUI Validator API page.
- Shouldn't it be that if no rule is set as an attribute in the input element (eg; required) then no validation is applied?
Behavior I am getting:
- With no validation specific attributes on the input element at all, the validation rules still get applied when I call .validate()
- Hidden form elements are validated.
I am using the following kendo:

I have put together a fiddle that demonstrates this:
http://jsfiddle.net/codeowl/B5ML4/3/
And here is the code, for those that don't have access to fiddle, I have the following markup:
<form action="/" id="testForm">
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="text" id="testInput" value="">
<a id="testValidate" href="javascript:;">Validate</a>
</form>
and the following script:
var validatable = $("#testForm").kendoValidator({
rules: {
testRule1: function (input) {
// Only "Tom" will be a valid value for the FirstName input
return input.is("[name=firstname]") && input.val() === "Tom";
},
testRule2: function (input) {
return $.trim(input.val()) !== "";
}
},
messages: {
testRule1: "Your name must be Test",
testRule2: "Your name must be Foo"
}
}).data("kendoValidator");
$("#testValidate").click(function () {
if (validatable.validate()) {
alert('passed');
}
});
and when I press the validate link it shows validation messages for the hidden fields.
