transparent borders form

Hello William,

What you can do is use the TransparencyKey property and set the BackColor of the title bar, but this way you will not be able to click in the transparent regions. This is a WinForms limitation and we do not have control over it. More information about this can be found in the following thread: How do I create a fully transparent in C# that is interactive? - Stack Overflow

I hope this helps. Should you have any other questions do not hesitate to ask.

Hi ,

This is what i did:

  this.FormElement.TitleBar.BackColor = Color.LightGreen;
  TransparencyKey = Color.LightGreen;

But it does not work .

I see someone does:

this.FormBorderStyle = FormBorderStyle.None;

But i do not want to hide it, juts make it transparent like attach file.

Hi William,

Here is how you can set the BackColor of the title bar:

Still using this approach is not reliable because you will be unable to drag the form. The transparency is limited in WinForms and there is no good way to overcome this limitation.

I hope this helps. Should you have any other questions do not hesitate to ask.
