Remove the title bar in Windows Forms

How can I remove the blue border that's on top of the Window Form? (I don't know the name of it exactly.)

Solution 1:

You can set the Property FormBorderStyle to none in the designer, or in code:

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

Solution 2:

if by Blue Border thats on top of the Window Form you mean titlebar, set Forms ControlBox property to false and Text property to empty string ("").

here's a snippet:

this.ControlBox = false;
this.Text = String.Empty;

Solution 3:

Solution 4:

Also add this bit of code to your form to allow it to be draggable still.

Just add it right before the constructor (the method that calls InitializeComponent()

private const int WM_NCHITTEST = 0x84;
private const int HTCLIENT = 0x1;
private const int HTCAPTION = 0x2;

///
/// Handling the window messages
///
protected override void WndProc(ref Message message)
{
    base.WndProc(ref message);

    if (message.Msg == WM_NCHITTEST && (int)message.Result == HTCLIENT)
        message.Result = (IntPtr)HTCAPTION;
}

That code is from: https://jachman.wordpress.com/2006/06/08/enhanced-drag-and-move-winforms-without-having-a-titlebar/

Now to get rid of the title bar but still have a border combine the code from the other response:

this.ControlBox = false;

this.Text = String.Empty;

with this line:

this.FormBorderStyle = FormBorderStyle.FixedSingle;

Put those 3 lines of code into the form's OnLoad event and you should have a nice 'floating' form that is draggable with a thin border (use FormBorderStyle.None if you want no border).

Solution 5:

 Me.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None
