I'm using SfPopup.PopupStyle to set the OverlayColor
1.- When I set the OverlayColor with XAML
<sfPopup:SfPopup x:Name="sfPopup"
OverlayMode="Transparent">
<sfPopup:SfPopup.PopupStyle>
<calendar:PopupStyle OverlayColor="#e7b04a40"/>
sfPopup:SfPopup.PopupStyle>
sfPopup:SfPopup>
I got this result:

2. When I set the OverlayColor by code behind
<sfPopup:SfPopup x:Name="sfPopup"
OverlayMode="Transparent">
sfPopup:SfPopup>
public MainPage()
{
InitializeComponent();
sfPopup.PopupStyle = new Syncfusion.Maui.Popup.PopupStyle
{
OverlayColor = Color.FromHex("#e7b04a").WithAlpha(0.25f)
};
}
I got this result

Take into account that:
- #e7b04a is RGB (231, 176, 74)
-
#e7b04a40 is RGBA(231, 176, 74, 0.25)
Is there a workaround for that?
