WebDataMenu-SubMenu Items disappear
posted

I have a WebDataMenu that is initially loaded on Page Load, but not for postbacks. The problem is that when I hover over a parent menu and the submenu items are displayed, moving the mouse down to select a submenu item causes them to disappear. Generally, I get one or two parent menus that will work properly, but the rest will hide the submenu list when I try to select something. It isn't always the same one, that part seems to be random. only by clicking repeatedly on the parent menu will the submenu finally stay put so something can be slected. I am using VS2008SP2, Infragistics 3.5 10.3.20103.2134. I cannot upgrade controls at this time and must make this work before 10/1 launch date. Any suggestions?

    Hello Dbishop9,

    Can you please provide me the markup and codebehind for the WebDataMenu?

    These are stripped down to the relevant code. I have to build these dynamically from the dataset due to requirements, I cannot use an SQLAdapter or OLEDBAdapter.
