I am using Visual Studio 2008 with SP1 and .Net 3.5 SP1 on a Vista Ultimate machine.
Machine is a Dell XPS 420 with 3 GB RAM.
1. On a web form I insert a menu control from the Toolbox's Navigation tab.
2. I edit the menu and create items with URLs etc in Design view. The html in the aspx source is updated correctly and changes appear correctly.
3. Save the aspx file and close it (or leave open and continue working).
4. I edit the menu again to add more items (or any other action that affects the menu design) in Design view and save. The changes do not appear in the html in the source, yet switching between Design and Source shows the changes in Design, but not in html. If I close the aspx file and reopen it, the changes made to the menu do not appear in Design nor in html in the source. After the initial menu creation and editing, it appears that menus always have to be edited in source view and saved. if I do that all is well, but it is so inconvenient and tedious. Same occurs in Split view - html doe not update to match Design view changes.
