jQuery Validate Plugin overwrite my select onChange postback

I'm creating this form (.net) where i have a select with a postback, that will trigger a action depending on which option i select. I'm trying to use the jQuery Validate Plugin (plugin website) to validate my form.

My problem is, when i validate the form, and my select is marked as invalid, the validation plugin overwrite it's onChange method to make it unmark when i change the value, the thing is that it's deleting my _开发者_如何学Python_dopostback from the onchange, making the form 'useless'.

Is there a way to the plugin validate my selects without deleting my postback action from the onchange?

I know this is an old post, but I had a similar situation and was able to resolve it like this. Just thought I'd post it just in case someone else found there way here. I'm using jQuery Validation Plugin 1.9.0:

$('#aspnetForm').validate({
    errorLabelContainer: "#messageBox",
    wrapper: "li"
});

$("input[id$='myButton']").click(function () {
     SetRules();
     if ($('#aspnetForm').valid()) {
          // form passed validation

     } else {
          $('#aspnetForm').resetForm();
          return false;
     }
});

function SetRules(){
     $("select[id$='myDropDown']").rules("remove");
     $("select[id$='myDropDown']").rules("add", {required:true});
}

My validator is set up so errors display together in one designated div. When I click the button, the validation fires and displays all the elements in that div and marks the fields that are invalid, including the select (all choices are red), and when I change the selection my autopostback fires and the colors of the select change back to their old value (assuming the choice passed the validation).

I am pretty new at this plugin, so I can't explain it too well but my thought process was to try and get the form to validate and show the errors, and then reset the controls back to their original state while still keeping the error messages visible. I was expecting to lose the red error highlighting, but somehow that retained while also bringing back the select's postback.

Also, I do not know if setting the rules in this manner contributed to this working or not; I had to set them like this for various reasons, the biggest one due to needing the selector for .NET's automatically generated IDs.
