Creates a button that will return back to the page you came from
Use the following syntax:
Properties:
ReturnUrl (String) - Default ReturnURL if none is specified. Defaults to Home page (Default.aspx). Note: use of the ASP.Net "~" is a legal character for specifying a relative path.
ReturnURLSite(String) - Default ReturnURL if you want to redirect to a different site. Set the value to the entire path of the site you want to redirect to. ie, http://www.MySite.com/MyPage.html. Note that this property must be URL encoded. In .Net you do this with HttpUtility.UrlEncode("http://www.MySite.com/Mypage.html")
