Using 9.2.20092.2090
With a Radial Gauge is it not possible to set the background color to Transparent?
how is the background panel using a gradient? is it the BackgroundImage property? transparent background support is not standard in Windows Forms, but the gauge control does support it. if you have a gauge on a form with a BackgroundImage, you should be able to see the BackgroundImage.
Let me rephrase that a bit.
When transparency is set and the background panel uses a gradient the transparency does not respect the gradient and simply displays the first color.
