Question

If I have a Horizontal StackPanel with many elements, with different margin between them:

Is there any difference if I give each element a left margin or
is there some advantage giving every second element a right and left margin – that way only one element gets its margin property set.

<StackPanel Orientation="Horizontal">
<TextBlock Name="textblock1" />
<TextBlock Name="textblock2" Margin="5,0,0,0" />
<TextBlock Name="textblock3" Margin="10,0,0,0" />
...
</StackPanel>

or

<StackPanel Orientation="Horizontal">
<TextBlock Name="textblock1" />
<TextBlock Name="textblock2" Margin="5,0,10,0" />
<TextBlock Name="textblock3" />
...
</StackPanel>

I was just wondering if there was a best-practise concerning this.

Answer 1

If the Margin is the same for every element, you can factor it out in a style:

<StackPanel Orientation="Horizontal">
   <StackPanel.Resources>
      <Style TargetType="TextBlock>
         <Setter Property="Margin" Value="5,0,0,0" />
      </Style>
   </StackPanel.Resources>
   <TextBlock Name="textblock1" />
   <TextBlock Name="textblock2" />
   <TextBlock Name="textblock3" />
   ...
</StackPanel>

Other than that it makes no difference.
