如何从可调整大小的窗口中移除最小化和最大化按钮？

I've stolen some code I found on the MSDN forums and made an extension method on the Window class, like this:

internal static class WindowExtensions
{
// from winuser.h
private const int GWL_STYLE      = -16,
WS_MAXIMIZEBOX = 0x10000,
WS_MINIMIZEBOX = 0x20000;


[DllImport("user32.dll")]
extern private static int GetWindowLong(IntPtr hwnd, int index);


[DllImport("user32.dll")]
extern private static int SetWindowLong(IntPtr hwnd, int index, int value);


internal static void HideMinimizeAndMaximizeButtons(this Window window)
{
IntPtr hwnd = new System.Windows.Interop.WindowInteropHelper(window).Handle;
var currentStyle = GetWindowLong(hwnd, GWL_STYLE);


SetWindowLong(hwnd, GWL_STYLE, (currentStyle & ~WS_MAXIMIZEBOX & ~WS_MINIMIZEBOX));
}
}

The only other thing to remember is that for some reason this doesn't work from a window's constructor. I got around that by chucking this into the constructor:

this.SourceInitialized += (x, y) =>
{
this.HideMinimizeAndMaximizeButtons();
};

Hope this helps!

Don't know if this works for your req. visually.. This is

<Window x:Class="DataBinding.MyWindow" ...Title="MyWindow" Height="300" Width="300"
WindowStyle="ToolWindow" ResizeMode="CanResizeWithGrip">

You can set the ResizeMode="NoResize" of the window if you want to remove Minimize and Maximize button

Here's a solution I'm using. Note that maximize button is still displayed.

Markup:

<Window x:Class="Example"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Example"
StateChanged="Window_StateChanged">

Code behind:

// Disable maximizing this window
private void Window_StateChanged(object sender, EventArgs e)
{
if (this.WindowState == WindowState.Maximized)
this.WindowState = WindowState.Normal;
}

One way is to set your ResizeMode="NoResize". It will behave like this.

I hope this helps!

If anyone use Devexpress window (DXWindow) accepted answer doesn't work. One ugly approach is

public partial class MyAwesomeWindow : DXWindow
{
public MyAwesomeWIndow()
{
Loaded += OnLoaded;
}


private void OnLoaded(object sender, RoutedEventArgs routedEventArgs)
{
// hides maximize button
Button button = (Button)DevExpress.Xpf.Core.Native.LayoutHelper.FindElementByName(this, DXWindow.ButtonParts.PART_Maximize.ToString());
button.IsHitTestVisible = false;
button.Opacity = 0;


// hides minimize button
button = (Button)DevExpress.Xpf.Core.Native.LayoutHelper.FindElementByName(this, DXWindow.ButtonParts.PART_Minimize.ToString());
button.IsHitTestVisible = false;
button.Opacity = 0;


// hides close button
button = (Button)DevExpress.Xpf.Core.Native.LayoutHelper.FindElementByName(this, DXWindow.ButtonParts.PART_CloseButton.ToString());
button.IsHitTestVisible = false;
button.Opacity = 0;
}
}

This variant of the solution proposed by @MattHamilton can (and must) be called in the constructor of the Window. The trick is to subscribe a delegate to the SourceInitialized event within the extension method.

private const int GWL_STYLE = -16, WS_MAXIMIZEBOX = 0x10000, WS_MINIMIZEBOX = 0x20000;


[DllImport("user32.dll")]
extern private static int GetWindowLong(IntPtr hwnd, int index);


[DllImport("user32.dll")]
extern private static int SetWindowLong(IntPtr hwnd, int index, int value);


/// <summary>
/// Hides the Minimize and Maximize buttons in a Window. Must be called in the constructor.
/// </summary>
/// <param name="window">The Window whose Minimize/Maximize buttons will be hidden.</param>
public static void HideMinimizeAndMaximizeButtons(this Window window)
{
window.SourceInitialized += (s, e) => {
IntPtr hwnd = new System.Windows.Interop.WindowInteropHelper(window).Handle;
int currentStyle = GetWindowLong(hwnd, GWL_STYLE);


SetWindowLong(hwnd, GWL_STYLE, currentStyle & ~WS_MAXIMIZEBOX & ~WS_MINIMIZEBOX);
};
}

Just use

WindowStyle="ToolWindow"

It hides the maximize and minimize buttons, but the window can still be resized by dragging the window borders and minimize using the hide button in the bottom right corner of the taskbar.
