    Hi Guys,

    I have a user registration form, and would like to have a background Username checker.. That is, once the user exits the txtUsername TextBox, a background action happens, which checks if the Username already exists. I'm no Ajax or Asp.Net guru (yet), but could someone help me out with either ideas, or a link to where this might be explained?

    I think Ajax will do it for me, somehow, but not sure.

    The user should be able to carry on using the site while the check happens, so a postback (and subsiquent refresh of the screen) isn't really an option.

    Thanks.
