I&#039;m using as aspx file inside of a regualr frameset. I have a .css file linked in to render the styles on the page.<BR><BR>When I first load the page, everything looks as expected. When I click one of the drop down lists that posts back, the postback works as expected but it looks like all my styles are gone. It just renders as plain black text. I&#039;ve tried moving the css file to the same directory and it gives the same behavior. <BR><BR>I&#039;ve noticed this only occurs when running the page in the frame. When I open it in a new window it keeps the stylesheet on postback. <BR><BR>Please help!
