How to set properties on child elements?

Question

WPF

There is a need to set the text color and padding for each child element of the TreeView. How can this be done without assigning these properties to each element separately? WPF project.

<TreeView Padding="0,3,0,0" Background="#FF09304A">
    <Label Content="Формула 1" Foreground="White" Margin="10"/>
    <Label Content="Формула 2" Foreground="White" Margin="10"/>
    <Label Content="Формула 3" Foreground="White" Margin="10"/>
</TreeView>

Answer 1

You can set general styles for elements in resources.
In this case, you can apply your styles to all types of elements or explicitly specify the name.
In the simplest case, it looks like this:

<TreeView Padding="0,3,0,0" Background="#FF09304A">
<TreeView.Resources>
<Style Type="Label">
<Setter Property="Foreground" Value="White" />
<Setter Property="Margin" Value="10" />
</Style>
</TreeView.Resources>
    <Label Content="Формула 1" />
    <Label Content="Формула 2" />
    <Label Content="Формула 3" />
</TreeView>
