I recently changed my XAML in order to gain the capability to right-justify menu items such as setting font sizes in the below graphic:
File Configure Help +-------------+ +----+ | Font size > |->| 8 | | Speed > | | 10 | +-------------+ | 12 | +----+
Obviously, based on that graphic, I won't be moving from a technical role into graphic design anytime soon :-) It's more just to illustrate what I meant.
The original XAML below did not right-justify the values
<MenuItem Header="_Configure">
<MenuItem Header="_Font size ">
<MenuItem Header="_8" Click="menuConfigFontSz8" />
<MenuItem Header="1_0" Click="menuConfigFontSz10" />
<MenuItem Header="1_2" Click="menuConfigFontSz12" />
</MenuItem>
:
</MenuItem>
Instead, it gave me:
File Configure Help +-------------+ +----+ | Font size > |->| 8 | | Speed > | | 10 | +-------------+ | 12 | +----+
So, to get right-justification, I changed it to:
<MenuItem Header="_Configure">
<MenuItem Header="_Font size ">
<MenuItem Click="menuConfigFontSz8">
<MenuItem.Header>
<TextBlock HorizontalAlignment="Right">_8</TextBlock>

</MenuItem>
<MenuItem Click="menuConfigFontSz10">
<MenuItem.Header>
<TextBlock HorizontalAlignment="Right">1_0</TextBlock>
</MenuItem.Header>
</MenuItem>
<MenuItem Click="menuConfigFontSz12">
<MenuItem.Header>
<TextBlock HorizontalAlignment="Right">1_2</TextBlock>
</MenuItem.Header>
</MenuItem>
</MenuItem>
:
</MenuItem>
However, I find I've lost the shortcut capability of doing AltC, F, 0 for selecting font size 10 (it's just the 0
bit that no longer works, the first two bits are still fine).
Instead it gives me the literal text 1_0
in the menu itself rather than allowing me to use 0
as a quick way of selecting the item:
File Configure Help +-------------+ +-----+ | Font size > |->| _8 | | Speed > | | 1_0 | +-------------+ | 1_2 | +-----+
How do I keep the right justification of the menu text but still allow for an accelerator?
When you add an accelerator to a MenuItem (and Button) WPF automatically adds a TextBlock to your MenuItem, and this probably prevents your code from working. You can see this effect if you take a look at the answer to this question.
This code solves the problem if you do not have a generic TextBlock style in your resources that overrides the default TextBlock behaviour.
<MenuItem Header="_Configure">
<MenuItem Header="_Font size">
<MenuItem Click="menuConfigFontSz8" Header="_8" HorizontalAlignment="Right"/>
<MenuItem Click="menuConfigFontSz10" Header="1_0" HorizontalAlignment="Right"/>
<MenuItem Click="menuConfigFontSz12" Header="1_2" HorizontalAlignment="Right"/>
</MenuItem>
