Office Window

Using it

Derive your form from ModernChromeWindow instead of Form. Add controls to it as usual; the title bar and border sit outside the client area, so docking and anchoring work against the content area. Control.Text or TitlebarText is the caption, and Form.Icon is drawn at its left.

Themes

WindowChromeTheme picks one of the built-in looks; the default is WindowChromeTheme.OfficeBlack. Choosing a built-in theme sets the chrome colours, every command button's brushes and colours, and Control.BackColor, replacing any you had set. To use your own colours, set WindowChromeTheme to WindowChromeTheme.Custom first, then WindowChromeStartColor, WindowChromeEndColor, WindowChromeBorderColor and the command button properties. To draw the chrome entirely yourself, set ModernWindowChromeProvider.

Size of the frame

ChromeTitlebarHeight (32 by default) and ChromeBorderSize (8) are in logical pixels and scale with the display. Changing either grows or shrinks the window by the same amount, so the client area keeps its size, unless ShouldAutoResizeWindowHeightOnTitlebarHeightChange or ShouldAutoResizeWindowSizeOnBorderWidthChange is turned off.

The command buttons

Minimise, maximise/restore and close work by themselves. Handle WindowMinimizeRequested, WindowRestoreOrMaximizeRequested or WindowCloseRequested to take over a button: while the event has a handler the window no longer acts on that button itself – call Form.Close or set Form.WindowState in the handler. IsControlBoxEnabled greys all three out.

A window without a title bar

IsFullChromeDisabled keeps only the border – for a splash screen or a tool window that can still be moved and resized – and puts the title bar back as it was when turned off again.

A main window in the Visual Studio dark style, which asks before closing.

using System.Windows.Forms;
using Binarymission.WinForms.Controls.Windows;

public sealed class MainWindow : ModernChromeWindow
{
    public MainWindow()
    {
        Text = "Order Manager";
        WindowChromeTheme = WindowChromeTheme.VisualStudioDark;
        ChromeTitlebarHeight = 36;

        WindowCloseRequested += (sender, e) =>
        {
            if (MessageBox.Show(this, "Close Order Manager?", Text, MessageBoxButtons.YesNo) == DialogResult.Yes)
            {
                Close();
            }
        };

        Controls.Add(new DataGridView { Dock = DockStyle.Fill });
    }
}
