How I can align MenuItems in Menu to right?

Question

In a menu bar, I want to get the two last buttons (here RUN and ADD) to the right instead of left

I tried to use HorizontalAlignment without success:

<Menu>
    <Menu.ItemsPanel>
        <ItemsPanelTemplate>
            <DockPanel HorizontalAlignment="Stretch"/>
        </ItemsPanelTemplate>
    </Menu.ItemsPanel>
    <MenuItem Header="FILE"/>
    <MenuItem Header="EDIT"/>
    <MenuItem Header="VIEW"/>
    <MenuItem Header="RUN" HorizontalAlignment="Right"/>
    <MenuItem Header="ADD" HorizontalAlignment="Right"/>
</Menu>

Your issue is in the

<ItemsPanelTemplate>
    <DockPanel HorizontalAlignment="Stretch"/>
</ItemsPanelTemplate>

This is what describes the container your MenuItems will belong in. You need to use a panel here which allows you to horizontally align items to the right within it.

You could try keeping it as a DockPanel:

<DockPanel LastChildFill="False" HorizontalAlignment="Stretch"> 

And adding

DockPanel.Dock="Right"

To the MenuItems you need to align right, and

DockPanel.Dock="Left"

To the others. If this does not work, there are plenty of other panels you can use in place of the DockPanel in the ItemsPanelTemplate.
