Here’s an example I found (the way you’re obtaining a reference to your element object is probably different, but take a look at this anyway:

Element = <however your get your element>;  //--- Determine real element size and position relative to the main page. int ElementLeft = Element.offsetLeft; int ElementTop = Element.offsetTop; mshtml.IHTMLElement TmpElem = Element.offsetParent; while (TmpElem != null) {      ElementLeft = ElementLeft + TmpElem.offsetLeft;      ElementTop = ElementTop + TmpElem.offsetTop;      TmpElem = TmpElem.offsetParent; }
