Input Bindings and Tooltip on Ribbon Buttons

Hi Hamid,

You can set the button's InputGestureText to specify your own gesture string as needed.

Well I am doing this though Binding: Her eis the xaml:

<apribbon:Menu apribbon:Menu.IsMenuItemInputGestureTextVisible="True">
      <apribbon:Button Command="tbcommands:TaskBuilderRoutedCommands.ExpandRegions" />
      <apribbon:Button Command="tbcommands:TaskBuilderRoutedCommands.CollapseRegions" />
</apribbon:Menu>

 Then here is the command:

private static RibbonCommand m_ExpandRegions;
        public static RibbonCommand ExpandRegions
        {
            get
            {
                if (m_ExpandRegions == null)
                {
                    m_ExpandRegions = new RibbonCommand("ExpandRegions", typeof(Ribbon), R.ExpandRegions,
                        null, string.Empty);
                    InputBindingsManager.CommandInputBindings.Add(m_ExpandRegions, new KeyBinding { Key = Key.E, Modifiers = ModifierKeys.Shift });
                }

                return m_ExpandRegions;
            }
        }

Unfortunately the Shift Modifier will not let me add it as gesture as such:

m_ExpandRegion.InputGestures.Add(new KeyGesture(Key.E, ModifierKeys.Shift)); < Does not work

But I add the CommandBinding with attached behavior as you had suggested, and I also handle the InputBinding (KeyBinding), except I need the Text for the KeyBinding to show the MenuItem. I do not want to add in xaml UNLESS I can bind it to something.

        private static void OnRegisterCommandBindingChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
        {
            UIElement element = sender as UIElement;
            if (element != null)
            {
                CommandBindingCollection bindings = e.NewValue as CommandBindingCollection;
                if (bindings != null)
                {
                    foreach (CommandBinding binding in bindings)
                    {
                        element.CommandBindings.Add(binding);
                        if (InputBindingsManager.CommandInputBindings.ContainsKey(binding.Command))
                        {
                            element.InputBindings.Add(InputBindingsManager.CommandInputBindings[binding.Command]);
                            //InputBindingsManager.CommandInputBindings.Remove(binding.Command);
                        }
                    }
                }
            }
        }

 Everything works fine as far as I can see except to pull the KeyBinding and sticking it in the MenuItem same as Gestures.

If you can give me a quick hint, or it can not be done this way? forcing me to put it in xaml?

Hi Hamid,

Maybe you could inherit RibbonCommand and add a property for InputGestureText on that and then bind to it like:

<apribbon:Button Command="tbcommands:TaskBuilderRoutedCommands.ExpandRegions"
    InputGestureText="{x:Static tbcommands:TaskBuilderRoutedCommands.ExpandRegions.InputGestureText}" />

Then just make that InputGestureText property non-null if it's the one scenario you're having trouble with.

Thank you, I figured I would have to do something like that to keep the entire project sort of dynamic where everything is defined in one place.
