How to move borderless wpf window without code behind file
提问by rhe1980
I'm creating a WPF application with a borderless window. Applying the MVVVMpattern (with help of Caliburn.Micro) I do not have a code behind file but only a XAML file.
我正在创建一个带有无边框窗口的 WPF 应用程序。应用MVVVM模式（在 Caliburn.Micro 的帮助下）我没有代码隐藏文件，只有一个 XAML 文件。
In several posts I found following solution:
在几篇文章中，我找到了以下解决方案：
XAML:
XAML：
<Window
...
WindowStyle="None" MouseLeftButtonDown="WindowMouseLeftButtonDown"/>
Code behind:
后面的代码：
private void WindowMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
DragMove();
}
Now I'm searching a solution to define this completely in XAML.
现在我正在寻找一个解决方案来在 XAML 中完全定义它。
Any idea?
任何的想法？

The solution I will present is not really advised, but you can put your code behind right in your XAML file like this:
我将提出的解决方案并不是真正建议的，但您可以将代码放在您的 XAML 文件中，如下所示：
<Window
...
WindowStyle="None" MouseLeftButtonDown="WindowMouseLeftButtonDown"/>
<x:Code>
<![CDATA[
private void WindowMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
DragMove();
}
]]>
</x:Code>

You can download the Microsoft.Windows.Shell dll (Link. You can find another download options with google), which gives you a property of CaptionHeight that enables tou to drag the window from its top part (like a normal window).
您可以下载 Microsoft.Windows.Shell dll（链接。您可以使用 google 找到另一个下载选项），它为您提供 CaptionHeight 属性，使您可以从顶部拖动窗口（就像普通窗口一样）。

You can use an EventCommandTrigger. Check these references:

I know that I am a little late to the question, but this is what I have been using for sometime now and it works like a charm.
我知道我提出这个问题有点晚了，但这就是我现在一直在使用的方法，它的作用就像一个魅力。
DashboardViewModel viewModel;
public DashboardView()
{
InitializeComponent();
viewModel = new DashboardViewModel();
viewModel.RequestClose += (s, e) => Application.Current.Dispatcher.Invoke(this.Close);
viewModel.RequestMinimize += (s, e) => Application.Current.Dispatcher.Invoke(() => { this.WindowState = WindowState.Minimized; });
DataContext = viewModel;
}
and something like this in your viewModel
在你的 viewModel 中类似这样的东西
#region Public Event Handlers
public event EventHandler<EventArgs> RequestClose;
public event EventHandler<EventArgs> RequestMinimize;
#endregion
Using the ICommand interface...
使用 ICommand 接口...
#region ICommand Members
public ICommand CloseCommand { get; private set; }
public ICommand MinimizeCommand { get; private set; }
#endregion
Configure the commands...
配置命令...
private void SetupCommands()
{
CloseCommand = new RelayCommand(CloseApplication);
MinimizeCommand = new RelayCommand(MinimizeApplication);
}
Here is the RelayCommand class.
这是 RelayCommand 类。
public class RelayCommand : ICommand
{
#region Private Readonly Properties
private readonly Action<object> executeCommand;
private readonly Predicate<object> canExecute;
#endregion
#region Constructors
public RelayCommand(Action<object> execute) : this(execute, null)
{
}
public RelayCommand(Action<object> execute, Predicate<object> canExecute)
{
if (execute == null)
throw new ArgumentNullException("execute");
this.executeCommand = execute;
this.canExecute = canExecute;
}
#endregion
#region Public ICommand Members
public bool CanExecute(object parameter)
{
return canExecute == null ? true : canExecute(parameter);
}
public event EventHandler CanExecuteChanged
{
add { CommandManager.RequerySuggested += value; }
remove { CommandManager.RequerySuggested -= value; }
}
public void Execute(object parameter)
{
executeCommand(parameter);
}
#endregion
}
And some example methods...
和一些示例方法...
private void MinimizeApplication(object obj)
{
RequestMinimize(this, new EventArgs());
}
private void CloseApplication(object obj)
{
RequestClose(this, new EventArgs());
}
Hope this helps!
希望这可以帮助！
