We investigated this scenario locally and unfortunately there is an issue with the styling mechanism for RadChart. Still, RadGridView appears to work fine for me. Are there any further specifics than setting application theme and then specific theme for the control itself?
I have logged the chart issue, so our developers will research the possibilities to fix it.
As a temporary workaround for RadChart you can use the PaletteBrushes functionality
to overwrite the style of your series.
