I have built an asp.net page using a master page as a header. The master page contains the asp:menu control.
The main page shows a iframe. The iframe is added dynamically to a placeholder and shows pdf files. The problem that I have is in Firefox the drop down menu options are hidden behind the iframe; in IE the menu options show properly.
As you can see I did add a z-index to the code but it made no difference.
strHTML = "<iframe id='ifrReport' z-index='-100000' style='width:100%;height:650px;' src='pdfs/"+ strReportFile + "'></iframe>";//add iframe to previously defined placeholderplhIFrame.Controls.Add(new LiteralControl(strHTML));
Has anyone any idea how to overcome this problem?
