title: MaskedEdit Extender lost data on postback
body: <p>I am currently developping an web site that require DateTime entry and I am using MaskEdit extender on the TextBox used to enter the date and time. These DateTime are used as input to compute the total hours and other stuff that need to be displayed back on the same page (for previewing)</p>
  
  <p>However, after the postback using MS AJAX, my computed data shows but my DateTime entries clears. Before I updated to latest AjaxControlToolkit available for .NET 2.0, my entries was corrupted after the postback. The postback is triggered by a LinkButton. Before that I tried using AutoPostBack property of TextBox.</p>
  
  <p>Any ideas for a fix or should I consider ditching MS AJAX and start using another AJAX library either for ASP.NET or going to JS directly.</p>
  
  <p>Note that I can't use .NET 3.5 because the target server is using Windows 2000.....</p>
