### Issue

When network performance is slow and a postback is needed (such as when the user clicks on a radio button that displays another field), the Submit button still appears during the page load.

### Solution

A simple solution is to use client-side JavaScript to hide the submit button in all your web controls that triggers a `Page.PostBack`.

For example, If you have a `RadioButtonList` control that upon selection of a value will trigger a `PostBack` to show or hide the Subject field. In that `RadioButtonList`'s **Settings / Custom attributes / Add a new attribute** , add `onchange` with the code to hide the Submit button.
