Examples using the free Ajax.NET library

This example will post a form to the server, invoke the Test1 method there and return a HTML string.

On the server you will have a typical method with an additional attribute:

[Ajax.AjaxMethod]
public string Test1(string firstName, string familyName, string email, string comment)
{
  string html = "";
 
  html += "Hello " + firstName + " " + familyName + "
";
  html += "Thank you for your comment ";
  html += System.Web.HttpUtility.HtmlEncode(comment);
  html += ".";
 
  return html;
}
