This post has been migrated, original date 06 Oct 2009 I had a situation where I wanted a loading icon to appear when the user clicked submit in an ASP.NET form and the button to be hidden. However I didn't want the image to display if the form failed the client side validation. The solution is to call the Page_ClientValidate method that ASP.NET uses. It takes one parameter which is the name of the validation group the button belongs to.
  var button = $("#<%=button.ClientID%>");
  var loadingImage = $("#loadingImage");{
