.NET MAUI : Override the default style of a windows view (TextBox) - xaml

Question

I want to create a custom Entry with a completely personalized visual.
For this, I created a CustomEntryHandler to modify the native view of the windows platform but I can't override the basic windows style which imports some effects :
The background color that changes on over
The bottom border that is displayed when entry is focused
...
I think I understood that this style comes from the default style of windows, in the generic.xaml file.
Does anyone know how I can override this ?
protected override TextBox CreatePlatformView()
{
var nativeView = new TextBox();
nativeView.Margin = new Microsoft.UI.Xaml.Thickness(0, 0, 0, 0);
nativeView.FocusVisualMargin = new Microsoft.UI.Xaml.Thickness(0, 0, 0, 0);
nativeView.BorderThickness = new Microsoft.UI.Xaml.Thickness(0,0,0,0);
nativeView.Padding = new Microsoft.UI.Xaml.Thickness(0, 0, 0, 0);
nativeView.CornerRadius = new Microsoft.UI.Xaml.CornerRadius(0);
nativeView.Background = new SolidColorBrush(Colors.Transparent);
return nativeView;
}

UPDATE 11/10/22 : I also want to remove the Clear button of the TextBox.
Thanks in advance.

Answer 1

The easiest way would be to write a new Style and apply it to your control using this code:
var nativeView = new TextBox();
nativeView.Style = Application.Current.Resources["MyCustomTextBoxStyle"];
In your App.xaml, you need to add the following style:
<Style x:Key="MyCustomTextBoxStyle" TargetType="TextBox">
<!-- Your textbox style -->
</Style>
You can find the standard WinUI 2 TextBox style here. If you would like to remove the clear button, you could remove the button that is part of the TextBoxStyle here.
