Autopostback in c# code while keeping several textboxes and dropdownlists values
<p>I have several <code>textboxes</code>and <code>dropdownlists</code> on my form. When a user submits the form, I want to keep several of these values on the form but I also want to make them invisible for several seconds after the form submits, so the user knows the form has been submitted. I am pretty sure you need to do an <code>autopostback</code>in order to change the visibility of  <code>textboxes</code>and <code>dropdownlists</code> but I do not want to do an <code>autopostback</code> because I will lose the fields I want to keep. Any alternatives?</p>
