You can set the area color like this:
RadChart1.Series.Appearance.FillStyle.FillType = Telerik.Charting.Styles.FillType.Solid;
RadChart1.Series.Appearance.FillStyle.MainColor = Color.Red;
As for the drill-down functionality you need -- RadChart is rendered as an image, so embedding tab will not be supported. Still, RadChart supports image map rendering. You can control this through every element's ActiveRegion
RadChart1.PlotArea.XAxis.Items.ActiveRegion.Attributes = "onclick=alert('click');";
Note that for auto-generated axis items the above statement should be placed in the BeforeLayout
event handler as the axis items are not available before that.
