Question

I am trying to setup a windows.resoruces style that targets all textbox’s within all groupbox’s (so it would not target textbox’s that are not found within a groupbox)

I know I could use the x:key field, but was wondering if there was a way to target certain controls within controls for an entire window or application?

Answer 1

You could try a nested style for your TextBoxes in Style.Resources of GroupBox with Style.TargetType but without x:key.

<Style TargetType="GroupBox">
    <Style.Resources>
        <Style TargetType="TextBox">
            ...
        </Style>
    </Style.Resources>
</Style>
