MasterPages - Dynamically Created Menus Disappearing

I am playing around with creating some menus
dynamically, and they
create fine and show up ok when I want them to; but
when I select a
menu NavigateUrl at run time, the applicable url shows
up as
anticipated in the content place holder but the menu
disappears...

the menu is part of the master page and is not in the
content place holder...

anybody have any ideas?

am I missing something obvious?

when I create the same menu at design time it does not
exhibit this behavior...

thanks in advance.

That's good, but where is the code which does the dynamic generation of the
MenuItems collection...?

This is how I am binding, with the exception that I am calling
CreateMenuItemB inding from within the click event of a button for test
purposes...

As I said everything works fine, all menu items show up as anticipated, then
when I select a menu item which loads the applicable NavigateUrl into the
MasterPage ContentPlaceHol der I lose the menu, it disappears, although the
NavagateUrl *.aspx appears in the ContentPlaceHol der as it should...

If I can get the menu to stick around after I select the NavigateUrl from
the menu I created dynamically and display the NavigateUrl in the MasterPage
ContentPlaceHol der, then I can move forward with my idea that I am kicking
around...

Thanks in advance.

I'm not sure what you're doing here...

Generally speaking, in the MasterPage / ContentPage architecture, you do not
dynamically select the ContentPage through a menu - instead, you simply
navigate to another ContentPage which, when it loads, picks up its
MasterPage and merges the two files into one HTML document...

E.g. if you have Page1.aspx and Page2.aspx, both of which are ContentPages
and use the same MasterPage, your MenuItem should simply navigate to
Page2.aspx through its NavigateUrl property - it should certainly not be
trying to play about with the contents of the ContentPlaceHol der on the
MasterPage...

I hope this explains it better...

The master page that I am dynamically creating a menu on works fine...

I am trying to select the content page that I want to display on the same
master page; from the dynamic menu I created, much as you would do from a
TreeView control as is done on the MSDN page, it works as anticipated if I
create a static menu at design time; but using the same settings at runtime,
when I select a menu item it does display the content page as it is supposed
to but the menu disappears, even though it is part of the master page...
I want the menu to stick around in case I want to load a different content
page instead in the same MasterPage…

Thanks in advance.

I'm afraid it doesn't...
I want the menu to stick around in case I want to load a different content
page instead in the same MasterPage.
Still seems to me that you're doing this backwards...

Menus don't really work the same way as TreeViews...

To change the ContentPage, you simply navigate to the other ContentPage - it
will automatically pick up its MasterPage and redraw the menu for you...

I am navigating to the applicable content page, using the NavigateUrl that is
selected via the menu, when I do the menu disapears...
Oct 23 '06 #7
Dump a button on the masterpage and click on it..
Will the menu dissapear as well?
This is usually due not rebuilding the menu again on page load.

sorry if i'm way off here.

thats how I am testing it, when I click on the button on the master page, I
dynamically build a menu, and it looks and works like I want it to at that
point...
then when I select a menu item which is wired to NavigateUrl to display the
applicable content page in the same master page's content place holder, it
shows the content page but the menu disappears...

thanks in advance.

Ah well alright then - but that isn't, in fact what you actually said... You
said "...then when I select a menu item which loads the applicable
NavigateUrl into the MasterPage ContentPlaceHol der...", which is what I
thought you meant!

That's fine - you appear to be doing it correctly - you just have a problem
with nomenclature. Selecting a menu item doesn't load the applicable
NavigateUrl into the MasterPage ContentPlaceHol der - it's precisely the
reverse. Selecting a menu item navigates to the ContentPage which loads its
MasterPage.

However, that's by the by...

Back to the original question - where is the code which does the dynamic
menu creation...?
