RibbonDropDownItems not visible after creating new mail RRS feed

  • Question

  • For every receiver the user types in the "To" field my add-in will create a corresponding `RibbonDropDown` item which I will add in a `RibbonGallery`. After the event is triggered the following code is executed:

        private void updateGallery(string name, string address, string gender, double probability)

    Microsoft.Office.Tools.Ribbon.RibbonDropDownItem itemReceiver = Globals.Factory.GetRibbonFactory().CreateRibbonDropDownItem();
    itemReceiver.ScreenTip = address;
    itemReceiver.Tag = gender;
    itemReceiver.Label = name;
            itemReceiver.SuperTip = (probability * 100).ToString() + " % Probability";


    Note: *gallery1* is the `RibbonGallery`.

    In the first mail item the UI works as intended. When the user is creating a new mail the gallery doesn't update its items anymore. The code will still be executed, but the new items will not be shown in the UI.

    I tried using `Invalidate`, but either I'm doing it wrong or/and it doesn't seem to work. The add-in also generates a salutation based on the contents of *gallery1*. The add-in generates a salutation in the mail body, so the content of *gallery1* is legit but not shown at all. I would like to add some pictures to show you the UI, but I'm not allowed to add images or links to this thread since my account is still getting verified.
