Declare Vector3 values directly in xaml-CodePudding

I want to implement to Vectore3 values as constants values in ResourcesDictionary but sadly an error just appears saying "Vector3 doesn't support direct content" Is there any way to do this??

I expecting that Vector3 to be applied in xaml directly like x:Double, x:String ...etc

CodePudding user response：

Currently only four intrinsic data types are supported in UWP xaml.

x:Boolean
x:String
x:Double
x:Int32

you can get more information from this document XAML intrinsic data types.

So you can't use Vector3 in xaml, you need create this struct in your code behind.

As @JunjieZhu-MSFT mentioned above there is no way to make data type struct values beside those four, so I worked as follow:

<x:string x:key="ShadowOffsetXY">0 2 0</x:string>

Then I made class that implement IValueConverter to convert this string value to Vector3 Value

  public class StringToVector3Converter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, string language)
        {
            if (value != null && value.GetType() == typeof(string))
            {
                var values = ((string)value).Split(" ");
                return new Vector3(float.Parse(values[0]), float.Parse(values[1]), float.Parse(values[2]));
            }

            return null;
        }

        public object ConvertBack(object value, Type targetType, object parameter, string language)
        {
            throw new NotImplementedException();
        }
    }

Then use this converter in the property of control that I want to bound this source value from

<ui:Effects.Shadow>
   <media:AttachedCardShadow Offset="{Binding Source="{StaticResource ShadowOffsetXY}, Converter={StaticResource StringToVector3Converter}" }" />
</ui:Effects.Shadow>
