I have a very simple menu using the ASP.NET menu control.  Got it working in a mock up project, no fuss, no muss.

Added it to my real project, same settings, same css, same XML source file, put it in the same control which is held by an identical master page.

Ran the project.  Looks like crap.  The dropdown isn't dropping down, it is showing in-line when the control displays.

Disable all other CSS and scripts on the page -- same problem.

Finally I pull out ye old DOM Viewer and voila -- in my mock up, the menu is rendering the dropdown in an IFrame, while in the real app, there was no IFrame created and crapitude resulted.

So, has anyone run across this before?  Any suggestions would be greatly appreciated.

BTW, there is one difference in the projects.  The real application is an ASP.NET Web Project (the belated VS add-in), while the mock up is in an out of the box Web Site.

I've never seen that before, so all I can offer is some wild speculation.

When you mentioned the IFRAME the first thing I thought of was a master page, and since you are using master page, I get a strong feeling about that.  My only guess is that in the mock up, you somehow got the menu into the content portion of the page, while on the real page you have it correctly in the frame portion.

No, the menu is in the "frame" portion in both applications.  But thanks for the thought.

OK,

More info, but no solution yet.

It's not IFrame issue per see.  In both projects the IFrame is created dynamically, it is not rendered in the page source.

In the working web site pages, the bookkeeping controls, _EVENT_TARGET, etc. are wrapped in a div and the master control is assigned and ID = ctl100.

In the problem project, there is no div wrapping the bookkeeping controls and and the master is assigned an ID = _ctl10.

Have no idea why this, or if it is related to the problem.  Just found it interesting.

meant

Good project master ID = ctl00

Problem project master ID = _ctl0

Uneffin' believable.  Must have been some naming disconnect somewhere in the javascript that menu control renders.  Maybe it doesn't like leading underscores.

I simply added this line In the master page's page_load event handler...

 Me.ID = "ctl00"

 

and the friggin' menu works.

It works. It works.
