    Hello,
    Is there a way to set the background color of items in the treemap, that would overwrite the colors from the CustomPalette.

    I made a example in paint below.



    Im currently using a class like this to load the treemap.

    class TreeMapItem
    {
    public string Color { get; set; }
    public string Category { get; set; }
    public double Amount { get; set; }
    public List<TreeMapItem> Items { get; set; }
    }


    Best Regards,
    Emil

    Hi Emil,
    For changing the Node Color, we need to handle the NodeRendering event and fill the color for the specified node.
    Please refer to the attached sample for reference.
