I need solution for auto adjust width height of iframe to fit with content in it, and the point is the content size (width, height) could be change after iframe loaded. I guess i need a event action when body size changed.

              Try this code it will solve the problem completely and it's simple:
<script language="JavaScript">
<!--
function autoResize(id){
    var newheight;
    var newwidth;
    if(document.getElementById){
        newheight=document.getElementById(id).contentWindow.document .body.scrollHeight;
        newwidth=document.getElementById(id).contentWindow.document .body.scrollWidth;
    }
    document.getElementById(id).height= (newheight) + "px";
    document.getElementById(id).width= (newwidth) + "px";
}
//-->
</script>
<IFRAME SRC="usagelogs/default.aspx" width="100%" height="200px" id="iframe1" marginheight="0" frameborder="0" onLoad="autoResize('iframe1');"></iframe>

              Not standards compliant, but by far the most easy way to do this.

                does it cross browser?

                @StoneHeart: yes, it's cross browser. The code is non-standard compliant because of contentWindow property, which isn't defined in DOM spec. In DOM spec exists property called contentDocument, but Internet Explorer 6 (and 7?) doesn't support it. The contentWindow property can be used instead and it's implemented in all common browsers (Gecko, Opera, Webkit, IE).

                BTW. the scrollHeight property - IIRC - also isn't standard compliant, but is also supported by all common browsers. You can use offsetHeight or other properties instead, but scrollHeight gives best results

            There are some issues with browsers.
Here is a cross-browser solution with jQuery:
