Doughtnut label color

[Enill]

Hi,
i applied an image texture on the different slice of a 2D doughnut chart with a custompalette.

The problem is that the image used for the texture is also the used in the background of every slice label. How can i change the background color of the different label?

Thanks in advance.

Hello Enill,

Here is a sample code snippet:

private Brush[] brushes = new Brush[] {
    new SolidColorBrush(Colors.Red),
    new SolidColorBrush(Color.FromArgb(64, 0, 255, 255)),
    new SolidColorBrush(Color.FromArgb(128, 255, 0, 255))
};

public MainPage()
{
    InitializeComponent();

    this.radChart1.CreateItemStyleDelegate = CustomItemStyle;
}

private Style CustomItemStyle(Control item, Style baseStyle, DataPoint dataPoint, DataSeries dataSeries)
{
    Style style = baseStyle;

    if (item is SeriesItemLabel)
    {
        SeriesItemLabel itemLabel = item as SeriesItemLabel;
        style = new Style(baseStyle.TargetType);
        style.BasedOn = baseStyle;

        Brush brush = brushes[dataSeries.IndexOf(dataPoint) % brushes.Length];

        style.Setters.Add(new Setter(SeriesItemLabel.FillProperty, brush));
    }
    return style;
}
