How to achieve transparent background of RadChart in a RadGrid cell?

[DAVE]

I am using Chart to create a small sparkline chart in a grid column.  Works great but I can't figure out how to get a truly transparent background on the chart.  I am setting colors thusly:

chart.PlotArea.Appearance.FillStyle.MainColor =

Color.Transparent;

 

chart.PlotArea.Appearance.FillStyle.SecondColor =

Color.Transparent;

 

But when the chart is displayed on an alternating color row the background of the chart is white, not transparent.

Hi Dave,

Please try the following code snippet ,remove the PlotArea,from your code.
chart.Appearance.FillStyle.MainColor = Color.Transparent;

Thanks,
