I tried it already and no luck...

 

ASP Error: Object doesn't support this property or method: 'ClientID'. So I changed it to ID and now get the following error:

Javascript Error: Object doesn't support this property or method
Line: 936

Below is my code/line #.

933 <script>
934 function changeBG(color) {
935      var editor1=document.getElementById('content');
936      var editdoc = editor1.GetDocument();
937      editdoc.body.style.backgroundColor=color; 
938 }
939 </script>

The ASP version is much different then the ASP.NET version... can you please provide a sample code that would allow this to work?
