WPF ComboBox: Align selected value and/or drop down items
<p>I have an almost default WPF ComboBox:</p>

<p><a href="https://i.stack.imgur.com/3oFKA.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3oFKA.jpg" alt="enter image description here"></a></p>

<p>What is the simplest way to align items, for instance, to the right <strong>in combobox's input and/or drop down?</strong></p>

<p>I've looked around and found only solutions messing with the control templates which in my opinion is too long shot for such a simple thing. I can't believe there is no simpler solution we can do for aligning the items.</p>

<p><strong>UPDATE</strong>:
I've slightly reformulated the question to cover a broader set of cases further readers might experience on this topic as it turned out thanks to dkozl's answer.</p>

<p>Also, it should prevent some people from trying to close this question as a duplicate.</p>
