'TextBox Stylings when Focused - WinUI 3.0
Similar to UWP TextBox Background when Focused
I am attempting to set some application-wide style guides for Focused TextBox elements in my application. My problem is that I would like to apply different styling to any Focused PasswordBox Elements on my page, but this solution applies the same styling to PasswordBox & TextBox.
Is there a way to explicitly apply the x:Key directive for TextBox elements only?
I was thinking there might be a way to use XAML <Style TargetType="TextBox"> but can't figure it out.

You need to get the default style for the TextBox control and modify its Focused VisualState.
You can learn how to locate the generic.xaml file here.
I brought this style from my laptop generic.xaml but it should also work on yours.

<!-- Other merged dictionaries here -->

<!-- Other app resources here -->
<!-- YOUR CUSTOM COLORS -->
<SolidColorBrush x:Key="CustomTextControlBackgroundFocused" Color="HotPink" />
<SolidColorBrush x:Key="CustomTextControlForegroundFocused" Color="YellowGreen" />
<SolidColorBrush

Opacity="1"
Color="SkyBlue" />
<!-- THIS IS FROM generic.xaml -->

And you can use it like this.

<PasswordBox />
