I understand your problem since this code example is more to be consider a conceptual example on how this can be achieved. The TransparentLabel.cs is invoking the OnPaintBackground in GradientTransparentTest.cs As you can see the OnPaintBackground is hardcoded with the gradient start color (silver) and the gradient end color (blue) and this causes your label to be filled with a gradient color not consistent to the gradient background. One way to solve this would be to calculate the exact color your background has at the start Y-position for the label. I might write a more sophisticated example covering this issue in the near future. Hi Mark.

However it doesnt work if you have your gradient fill TopToBottom (as opposed to LeftToRight, this is because it will fill the label based on the colors at the top of the screen, hence if the lable is lower down the screen the background doesnt look transparent. Any ideas how to solve this ? Nice bit of code.

Thanks for sharing the article as well as code. Very good, was searching for this stuff since last two weeks. Thanks for sharing the article as well as code.

Good luck on your WM app :) Bjorn: Feel free to use any code lines you find on this blog as if they were your own. Good luck on your WM app :)

I'm currently working on a application for WM, and I will use your lines when creating my gradients. I hope this isn't any problem. Thanks again. Thanks for sharing your code.
