Open Window Activate not working with button inside menu

Question

I have a really strange behaviour, and I hope someone can help me out.

I have the following XAML layout:

<StackPanel Orientation="Horizontal">
    <Menu>
        <Menu.Items>
            <MenuItem Padding="2,0,2,0">
                <MenuItem.Header>
                    <Button Content="Details"
                            Click="Details_Click" />
                </MenuItem.Header>
            </MenuItem>
        </Menu.Items>
    </Menu>
    <Button Content="Details"
            Click="Details_Click" />
</StackPanel>

Please notice that both buttons have the same Event registered. The Details_Click Event looks like this:

private void Details_Click(object sender, RoutedEventArgs e)
{
    var viewer = new DictionaryViewer();
    viewer.ShowActivated = true;
    viewer.Show();
    viewer.Topmost = true;
    viewer.Topmost = false;
    viewer.Activate();
    viewer.Focus();
    e.Handled = true;
    return;
}

Now I am facing the problem, even with all the code from above the Window doesnt show up activated when I press the button inside the Menu but outside of it works with just .Activate();. (How I know that window isnt activated: need 2 clicks to close/minimize/maximize it)

Why would my XAML Layout ruin the Activation of the DictionaryViewer(); window, with the button inside Menu?

(To your information the DictionaryViewer is totally empty, its a fresh window nothing implemented yet)

Edit:

Yes, I know there is the MenuItem_Click Event that may make it work, but I need/want the button inside the Menu how can I fix this issue?

I think the menu handles some events and gets the focus after the MenuItem was clicked — csharpwinphonexaml, Apr 07 '14 at 14:16
@MichalCiechan got it from here http://stackoverflow.com/a/4831839/2598770, since I am searching some time now and wondered why its not working and since 5 minutes when I moved button outside the menu i am in WTF mode... — Rand Random, Apr 07 '14 at 14:17
I think you shouldn't handle Button.Click inside menu but use Menu events to decide behaviour — csharpwinphonexaml, Apr 07 '14 at 14:19
@verdesrobert And since I want a button inside my Menu there is no way I can fix it? — Rand Random, Apr 07 '14 at 14:21
You can have the button but try to handle the Menu Click and not the Button Click — csharpwinphonexaml, Apr 07 '14 at 14:23
@verdesrobert viewer.Activate(); should bring it to the foreground. — Michal Ciechan, Apr 07 '14 at 14:35
Still if the Activate is called after the lines of code are executed it may go in an event like for example MouseUp or who knows what events are internally handled by Menu — csharpwinphonexaml, Apr 07 '14 at 14:38

THe reason this is happening is because the Button inside the MenuItem is gaining Focus after the Window has opened.

If you set the Focusable property of the button inside MenuItem, this fixes the issue.

E.g.

<StackPanel Orientation="Horizontal">
    <Menu>
        <Menu.Items>
            <MenuItem Padding="2,0,2,0">
                <MenuItem.Header>
                    <Button Content="Details"
                            Click="Details_Click"
                            Focusable="False" />
                </MenuItem.Header>
            </MenuItem>
        </Menu.Items>
    </Menu>
    <Button Content="Details"
            Click="Details_Click" />
</StackPanel>

I have a similar issue and am not understanding why if a menu item in the window is being focused on the window would not appear in the foreground? Also, the issue seems to be random in that sometimes the app/window will appear in the foreground and other times it will appear behind other windows... – m4gik Jan 26 '18 at 19:50
@m4gik ask a question and point to it, I will try to take a look – Michal Ciechan Jan 27 '18 at 17:16
