I have a very simple radChart and I am attempting to set the Fill Type to Gradient and use two KnownColors as the Main and Secondary Color. I have tried to do this progamatically and through the property panel. When setting the property in the property panel from Solid to Gradient it immediately goes back to gradient, however I am able to set it to hatched. Here is the code I am using. The is still solid white. Any help would be greatly appreciated.

KnownColor clrTopBackgroundColor = KnownColor.White;

KnownColor clrBottomBackgroundColor = KnownColor.LightBlue;

radChart1.PlotArea.Appearance.FillStyle.FillType = FillType.Gradient;

radChart1.PlotArea.Appearance.FillStyle.MainColor = Color.FromKnownColor(clrTopBackgroundColor);

radChart1.PlotArea.Appearance.FillStyle.SecondColor = Color.FromKnownColor(clrBottomBackgroundColor);

radChart1.Update();

radChart1.UpdateGraphics();

Thank you,
Will

Hi William,

We are unable to reproduce the issue you are facing on our local tests. You can see from the image attached that the background is set without problems. I've managed to change the colors both programmatically and through Properties in Design mode. Here is how the colors were set programmatically:

radChart1.PlotArea.Appearance.FillStyle.MainColor = Color.White;

radChart1.PlotArea.Appearance.FillStyle.SecondColor = Color.LightBlue;

Have in mind that the FillStyle.FillType is set to Gradient by default.

Do you use by any reason another Skin than the Default one? If this is your case turn off SkinsOverrideStyles property of the RadChart so that the Color changes will take effect.

All the best,

Evgenia,

I have SkinsOverrideStyles set to False. I am still unable to change the fill style to Gradient. If I try to change it to Gradient in the property window it automatically switches back to Solid when I click outside of the property box. Additionally I modified my code to match your code, and changing the color progamatically does not work either. I am using Windows Server 2008 R2 and VS2010. I would be happy to provide the project for demonstration purposes, but I cannot attach it to this forum. Please let me know the best option to provide the program.

Thank you,
Will
