Question

I need to define a global style for all TextBlock and TextBox that exist within ItemsControl elements.

I need all the TextBlock elements to have a Width of 100 and Left aligned, and the TextBox elements to have a width of 50 and to be Right aligned.

How can I achieve this?

I don’t understand your “that exist within ItemsControl elements” but if you are talking about your ItemsTemplate it should work like this

<Style x:Key="myTextBoxStyle">
    <Setter Property="Width" Value="50"/>
    <Setter Property="HorizontalAlignment" Value="Right"/>
</Style>

<Style x:Key="myTextBlockStyle">
    <Setter Property="Width" Value="100"/>
    <Setter Property="HorizontalAlignment" Value="Left"/>
</Style>

<ItemsControl>
    <ItemsControl.ItemsTemplate>
        <DataTemplate>
            <Grid>
                <TextBlock Style="{StaticResource myTextBlockStyle}"/>
                <TextBox Style="{StaticResource myTextBoxStyle}"/>
            <Grid>
        <DataTemplate>
    </ItemsControl.ItemsTemplate>
</ItemsControl>

This will display all items in your ItemsControl with a textbox which uses your myTextBoxStyle and your textblock with the myTextBlockStyle.
