I have set up a simple sample menu.
<Menu>
<MenuItem Header="Top Menu">
<MenuItem Header="Item 1">
<MenuItem Header="Sub Menu 2" />
</MenuItem>
</MenuItem>
</Menu>
Sub Menu 2 is opening on the left instead of the expected right side of the menu. I would expect this behaviour if the menu was near the edge of the screen, but window is centered on the screen and not near any edge.
Is there a property that controls where a MenuItem opens on the screen?
Does this happen on other applications on your system as well?
There’s a registry setting in the value
MenuDropAlignmentin the keyHKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windowsthat controls it system-wide. You might just check to make sure that it is set to 0 instead of 1.More info can be found in this article.
