Validators: Do they Stay disabled on postback when disabled ClientSide?

I have been learning alot about the standard asp.net Validators, and my latest discovery was about how to disable a validator client side, which was pretty cool.

now, if my initial post has the validator enabled, but client side, i disable it, does the server side recognize the client side change, and keep it, or does it get re-enabled the the page is sent back to the user?

Thanks!

Solution

  • .NET Server side validator controls will be reset to whatever they have been set to last in the server side code during a postback.

    So for example if you have set a required field validator to rqvControl.enabled = true in its .aspx tag, then after a postback it will be enabled no matter what its state was client side.

    If you are setting the state of a validator on the client side, and you want to persist it, then you will need to set a value that you can read in your server code during a postback. This can be as simple as setting a hidden field value from your javascript that is doing the enable/disable operation. In your codebehind just handle the enabled state of your validator based off the value in your hidden field.
