Remove client-side validation

Question

Assuming I have a specific problem which I need to remove some dataannotations's required attributes, how can I do this?

I know about view-model but I don't want to use it for some reasons.

Answer 1

this will disable the validations on certain elements based on a selector

var validationSettings = $.data($('#formToValidateId').get(0), 'validator').settings;  
validationSettings.ignore = '.ignore';

Answer 2

If you just want to disable validation for a single field in client side then you can override the validation attributes as follows:

@Html.TexBoxFor(model => model.SomeValue,                  
new Dictionary<string, object> { { "data-val", false }})
