I'm creating a .NET for Windows Mobile and using CF2.0, I tried to
set the background of a label which is over a picturebox to transparent
by changed its backColor to Transparent, but it doesn't work
during the run time, the label still has white background, anyway
to make it work?
 
Hello Steven,

Since this is a .NET Compact Framework question, I'd suggest you post it in
the Compact Framework newsgroup. You will find more qualified CF experts
and get better support there from the community. The newsgroup for .NET CF
is:

microsoft.public.dotnet.framework.compactframework

Thank you and I appreciate your understanding.

Besides, I'd still like to share some of my thoughts on this problem.

If this was on Windows Desktop, we can use a Panel control to contain a
picture instead of a PictureBox to make a Label control with background
color set to transparent work. This works because .NET will try to
*simulate* transparency, not because Windows supports this feature
natively. You may want to read the document on BackColor property for more
information (especially the Remark section):
http://msdn.microsoft.com/en-us/library/system.windows.forms.control.backcol
or(VS.80).aspx

However, this technique seems not working with CF. So I believe we
basically have two options:

1. Make our own custom Label control to support transparent background.

2. Do not use a label control at all, use DrawString method to paint the
string directly onto the picture.

Hi Steven,

Good to know you're going to create your own customized control. One of the
advantages of creating such a control over drawing string directly is that
we can reuse it easily.

Thank you for sharing with us and have a nice day.

Best regards,
