PAVCBC,

You can do this by looping through the UltraToolbarsManager Ribbon's Tabs collection, and then through each RibbonTab's RibbonGroups collection.  You then need to loop through each RibbonGroup's Tools collection.  If any of those tools are PopupMenuTools (that contain other tools), you will need to loop through their Tools collection as well.  The best way to do that last part is via aa recursive loop.  The code for the entire thing might look something like:

foreach (RibbonTab tab in this.ultraToolbarsManager1.Ribbon.Tabs)
            {
                foreach (RibbonGroup group in tab.Groups)
                {
                    foreach (ToolBase tool in group.Tools)  //this gives us all the tools directly in a RibbonGroup
                    {
                        if (tool.GetType() == typeof(PopupMenuTool))
                        {
                            PopupMenuTool pTool = tool as PopupMenuTool;
                            LoopThroughTools(pTool);
                        }
                    }
                }
            }

 private void LoopThroughTools(PopupMenuTool parent)
        {
            foreach (ToolBase child in parent.Tools)
            {
                if (child is PopupMenuTool)
                {
                    PopupMenuTool pTool = child as PopupMenuTool;
                    LoopThroughTools(pTool);
                }
            }
        }

Hope this helps,
