Hi gonzalo,
Both approaches should be working fine. Please, try setting the ChartSeriesItems' FillType:
radChart1.Series[0].Items[0].Appearance.FillStyle.FillType = FillType.Solid;
or
e.SeriesItem.Appearance.FillStyle.FillType = FillType.Solid;
If you still have problems setting the color, please, send a simple project that we can analyze.
Kind regards,
