Currently, you can customize the fill and stroke of the data point visuals using the DefaultVisualStyle property of the series. In the common scenario, you can use data bindings to data bind the fill and stroke of the corresponding element. Additionally, you can use the DefaultVisualStyleSelector for such customization. However, when the Direct2DRenderOptions or BitmapRenderOptions are used, data bindings and the DefaultVisualStyleSelector are not support. The bindings in the DefaultVisualStyle throw errors and the selector is not applied.

Add support for conditional styling. This should include support for data binding in the fill and stroke properties of the element from the DefaultVisualStyle, or support for DefaultVisualStyleSelector, or another type of API.
