Hi Larry,

I took a look at the AppStylistRuntime elements with the ElementViewer and it turns out that the panel in your screen shot is actually an UltraGroupBox.

Going a bit further I discovered that the GroupBox used in the AppStylist interface actually implements an image for its background; while I could not obtain the exact image, I was able to replicate the approximate behavior wherein the edges of the rounded image are blended with the background of its container control.

To do this, I edited a test image with Microsoft Paint, using the beveled rectangle tool set to the thickest width which I set to white, (any color could potentially be used). I then trimmed off the excess around this new border, saved the image and imported it into my sample.

I then set this image as the background image of the UltraGroupBox and set the background color of the container, (in this case the form itself) to white, in order to blend in with the image border.

I have attached the sample along with the test image for reference.

If you have any further questions at all regarding this approach, please let me know.

Sincerely,
