check the style attributes of a div in vb.net

Just as the title says, i have a div in the aspx side which has ID and runat=server. I have 2 functions in the vb.net side code, on of which adds style as div.style.add("display","none"). In the oth开发者_StackOverflow中文版er function i want to check if the div style display is none or not. How can i check that programatically?

got it. div.style.item("display"), will GET value of that item.
