How can I assign a dynamic resource in the constructor when creating a frame in C# instead of XAML?

Question

Here is the code that I currently have:

        var FR2 = new Frame()
        {
            Content = CE,
            CornerRadius = 5,
            HasShadow = false,
            HorizontalOptions = LayoutOptions.FillAndExpand,
            VerticalOptions = LayoutOptions.FillAndExpand,
            Padding = new Thickness(10, 0),
            Margin = new Thickness(0, 8),

        };
        FR2.SetDynamicResource(Frame.BackgroundColorProperty, "EntryBackgroundColor");
        FR2.SetDynamicResource(Frame.BackgroundColorProperty, "EntryBorderColor");

Is there a way I can set these dynamic resources

BackgroundColor
BorderColor

inside of the { } part of the constructor for FR2 instead of adding them after?

Answer 1

Unfortunately, no. You cannot set the dynamic resources inside your initialiser. You have to set them afterwards with the SetDynamicResource method.

As you can see, SetDynamicResource expects to be used with Element.SetDynamicResource() . So, at least for now, this is not possible.

Taking into consideration that for the upcoming MAUI , the guys from Microsoft are spending more time into markup extensions for the code-behind, I won't be surprised if it comes in the near future.

Btw, you have a copy-paste mistake in the last row - you are binding the EntryBorderColor to the BackgroundColorProperty again.
