asp.net disable/enable validator using Javascript

Question

I have a complex form requiring me to switch specific validators on or off depending on selections made by the user.

ValidatorEnable seems to do the job, but it seems that when I call this method it actually fires the validation process as well, without the user actually hitting the submit button.

Is that how it works?

I eventually found the best way to do this was to use the following code:

var validatorObject = document.getElementById('<%=ValidHasShippingLocationZip.ClientID%>');
validatorObject.enabled = false;
validatorObject.isvalid = true;
ValidatorUpdateDisplay(validatorObject);

it worked, I didn't use the isvalid property, I worked just with the enable or disable

Why I'm still able to submit my asp.net form while the above function works with my validators and display / hide the validator? I don't use isValid in my code behind!

@DKR make sure you find correct validatorObject, maybe you should use console.log(validatorObject) to see if the element was find correctly.

It worked, but has 1 problem, Page.Isvalid still returns false (I mean on code-behind side)

I wrote some code seems can meet your requests. Iterate validators and enable these you needs.

   ValidatorEnable(validatorObj, true);

then clear the screen,erase the error info.

Don't just post links, links die.

ValidatorEnable(valObj, enable) is now part of the .NET boilerplate code so this example can be used without additional code.
