How can I redirect from within a frame to a full web page?

You can call Response.Redirect() from within an IFrame and have the target page "bust out of the frame" by adding the following code to the target page's <head> element:

<head>
<script type=" text/javascript" >
          function bustOut()
          {
               if (window.top != window.self) 
               {
                    window.top.location=" TargetPage.aspx" 
               }
          }
</script>
</head>

And adding the folowing code in the form's body tag:

<body onload=" bustOut()" ></body>
