Question

I want to include a plus or minus button in my Windows Phone app. How can I change the content of the button to plus or minus?

<Button x:Name="buttonPlusOrMinus" 
            Content="+/-"
            HorizontalAlignment="Left" 
            Margin="180,217,0,0" 
            Grid.Row="2" 
            VerticalAlignment="Top"/>

Answer 1

There is a few ways to do this.

• Hold down the Alt key then type 0177 on the numpad and let go of Alt, this will cause you to type ±.

• Open up the program charmap in windows, find the character you are looking for, then click the "Select" then the "Copy" button. You will then be able to paste the ± character in your code.

• Copy the ± character from this question into your code.

  <Button x:Name="buttonPlusOrMinus" 
      Content="±"
      HorizontalAlignment="Left" 
      Margin="180,217,0,0" 
      Grid.Row="2" 
      VerticalAlignment="Top"/>
