Dynamic Popupmenus in MDI Child
posted

Hi

I'm using Office2007 UI (Ribbon) in an MDI application. In one of the child forms I want to add buttons dynamically to a popupmenu, but they don't show up. I've used the following code:

        private void toolbarsManager_BeforeToolDropdown(object sender, Infragistics.Win.UltraWinToolbars.BeforeToolDropdownEventArgs e)
        {
                    string key = "MyKey";

                    PopupMenuTool tool = (PopupMenuTool)e.Tool;
                    ButtonTool button = new ButtonTool(key);
                    button.SharedProps.Caption = "Name";

                    toolbarsManager.Tools.Add(button);
                    tool.Tools.AddTool(key);

        }

The toolbarsManager is the MDI Child toolbars manager, but I've tried to use the toolbarsManager.MDIParentManger and setting the optional parameter in AddTool to true without success.

UPDATE: If switching child forms back and forth, the dynamically added tools is shown the first time, but then not until you switch forms again. This feels a little bit like a bug to me.

Any help would be appricated. Thanks, Eric

    I am having the same problem. I've come up with this workaround, but you'll get a flicker on the child ribbon if it is visible:

     

    RibbonTab selTab = null;
    if (toolbarManager.MdiParentManager != null)
    {
        selTab = toolbarManager.MdiParentManager.Ribbon.SelectedTab;
    }
    toolbarManager.RefreshMerge();
    if (selTab != null)
    {
        toolbarManager.MdiParentManager.Ribbon.SelectedTab = selTab;
    }

     

    There ought to be a better way to tell a tool to be redrawn (the problem is that the tools *are* dynamically added, but don't shown up until the child tool is told to be redrawn. I bet it's possible to find the PopupMenu tool's representation on the parent ribbon and add the tools *there* and have it refresh right away without needing that workaround, but I haven't figured out how to do it.

     

    Still, I agree that it seems like a bug that dynamically adding tools to a top-level/parent popupmenu works fine, but we have this issue with child ribbons.
