Div Item not get Painted some times

[Guest]

I have a div control on my web page which to which i assign a XML document
which contains a HTML table as innerHTML, but sometimes table will not get
painted on web page.
Although the same get painted when i click on minimize and maximize button,
given below is the piece of javascript code i am using for the same

var divFullReport = GetElement("div_FullReport");
divFullReport.innerHTML = '';
divFullReport.innerHTML = xmlFinalStructure.xml;
This client side javascript code get executed when user press client side
button on web page.
