Aded controls lost on postback

Question

Hello,

I have added html controls through javascript, but when the page postback, all of the added controls are lost. Is there a way to retrieve it?

Thanks, JV

Answer 1

They will be,if you modify the dom with javascript the modifications will not persist through a postback, whether it is static html or dynamic server side generated you will get a new page. You need to re add the controls every time.

Answer 2

Because the controls are dynamically added with javascript, they are supposed to vanish. If feasible, you can put them directly in your html.

Answer 3

Seems like you have a couple of options. Either

1. Add a parameter to your POST to indicate that the fields were present, then if the server sees that that parameter is set, you write the fields out in your response; or

2. Do the form submission by AJAX, leaving your page undisturbed.
