    I want to change the background image of the html page within code based on
    the users selection.
    I'm trying to use this in the page onload even

    response.write("<body background=' & dataitem>")

    but i can't get it to work. if i hard code the dataitem in it will change
    but i need it to work with the item being passed in.

  2. Add javascript variable backgroundString and function onLoad() to the <head>
    section:

    var backgroundString;
    function onLoad(){document.body.background=backgroundString}

    In the html view write <body onload='onLoad()'>

    In the code-behind write (c#)
    Response.Write(String.Format("<script>backgroundString={0}<script>",
    dataitem));
