transparency of form controls in c#

Question

How to put transparency on certain element on windows form?

I have tried a lot of codes and still nothing.

This is what looks really logical to me but it's not working.

 SetStyle(ControlStyles.SupportsTransparentBackColor, true);
 label4.BackColor = Color.Transparent;

I have put this code in the constructor.

And this is the LINK

What colour is the label after that last line? – banging May 18 '12 at 19:52 — banging, May 18 '12 at 19:52

Labels are a bit stubborn but they can be made to have transparent background. Similar question was answered here: Transparent control over PictureBox

try adding this to the form itself...

this.TransparencyKey = System.Drawing.Color.Transparent;

You'd think it would be inherent, but in testing adding that did the trick. Then set the control to this...

Label1.BackColor = System.Drawing.SystemColors.Window;

That just worked in a test project not really sure why exactly. This will probably make most of your form transparent, but hopefully you can adjust some things.

Winforms do not have built in transparency for controls. You can, however work around this limitation.

Here is my favorite work around: http://www.doogal.co.uk/transparent.php
It works fairly well and is a generic solution rather then a "1 time" one.

additionaly, WPF handles transparency quite well, you could at least take a look at it – May 18 '12 at 21:13
