Place a dividing line in a menu in WPF
Solution 1:
Use a Separator like this:
<MenuItem Header="_Open" Command="ApplicationCommands.Open" />
<Separator />
<MenuItem Header="E_xit" Command="ApplicationCommands.Close" />
Solution 2:
I needed to iterate through MenuItems for various reasons, and using Separator meant a bit of casting, so I used a 1px high MenuItem instead
<MenuItem Height="1" Background="LightGray"/>
The correct answer most definitely is to use Separator, but the above works visually too, and can be a solution in some cases.
