It is possible to drag &amp; drop a form by clicking anywhere on the form, not just the title bar. This is handy if you have a borderless form.

This article on CodeProject demonstrates one possible solution to implement this:

<a href="http://www.codeproject.com/KB/cs/DraggableForm.aspx" rel="nofollow">http://www.codeproject.com/KB/cs/DraggableForm.aspx</a>

Basically a descendant of the Form type is created in which the mouse down, up and move events are handled. 

<ul>
<li>Mouse down: remember position </li>
<li>Mouse move: store new location</li>
<li>Mouse up: position form to new location</li>
</ul>

And here's a similar solution explained in a video tutorial:

<a href="http://www.youtube.com/watch?v=tJlY9aX73Vs" rel="nofollow">http://www.youtube.com/watch?v=tJlY9aX73Vs</a>

I would not allow dragging the form when a user clicks upon a control in said form. Users epexct different results when they click on different controls. When my form suddenly starts moving because I clicked a listbox, button, label...etc. that would be confusing.

Sure, apply the following <code>MouseDown</code> event of your <code>Window</code>

<pre><code>private void Window_MouseDown(object sender, MouseButtonEventArgs e)
{
 if (e.ChangedButton == MouseButton.Left)
 this.DragMove();
}
</code></pre>

This will allow users to drag the Window when they click/drag on any control, EXCEPT for controls which eat the MouseDown event (<code>e.Handled = true</code>)

You can use <code>PreviewMouseDown</code> instead of <code>MouseDown</code>, but the drag event eats the <code>Click</code> event, so your window stops responding to left-mouse click events. If you REALLY wanted to be able to click and drag the form from any control, you could probably use <code>PreviewMouseDown</code>, start a timer to begin the drag operation, and cancel the operation if the <code>MouseUp</code> event fires within X milliseconds.

blocks|key|3152761|text|如果wpf窗体需要是可拖动的，无论它是在哪里单击的，那么简单的变通方法是使用委托在windows+onload事件或网格加载事件上触发DragMove()方法|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3152762|private+void+Grid_Loaded(object+sender,+RoutedEventArgs+

if the wpf form needs to be draggable no matter where it was clicked the easy work around is using a delegate to trigger the DragMove() method on either the windows onload event or the grid load event

<pre><code>private void Grid_Loaded(object sender, RoutedEventArgs 
{
 this.MouseDown += delegate{DragMove();};
}
</code></pre>

<pre><code>private void Window_MouseDown(object sender, MouseButtonEventArgs e)

</code></pre>

Is throwing an exception in some cases (i.e. if on the window you also have a clickable image that when clicked opens a message box. When you exit from message box you will get error) 
It is safer to use

<pre><code>private void Window_MouseDown(object sender, MouseButtonEventArgs e)
{
if (Mouse.LeftButton == MouseButtonState.Pressed)
 this.DragMove();
}
</code></pre>

So you are sure that left button is pressed at that moment.

Sometimes, we do not have access to <code>Window</code>, e.g. if we are using <code>DevExpress</code>, all that is available is a <code>UIElement</code>.
<h2>Step 1: Add attached property</h2>
The solution is to:
<ol>
<li>Hook into <code>MouseMove</code> events;</li>
<li>Search up the visual tree until we find the first parent <code>Window</code>;</li>
<li>Call <code>.DragMove()</code> on our newly discovered <code>Window</code>.</li>
</ol>
Code:
<pre><code>using System.Windows;
using System.Windows.Input;
using System.Windows.Media;

namespace DXApplication1.AttachedProperty
{
 public class EnableDragHelper
 {
 public static readonly DependencyProperty EnableDragProperty = DependencyProperty.RegisterAttached(
 &quot;EnableDrag&quot;,
 typeof (bool),
 typeof (EnableDragHelper),
 new PropertyMetadata(default(bool), OnLoaded));

 private static void OnLoaded(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs dependencyPropertyChangedEventArgs)
 {
 var uiElement = dependencyObject as UIElement;
 if (uiElement == null || (dependencyPropertyChangedEventArgs.NewValue is bool) == false)
 {
 return;
 }
 if ((bool)dependencyPropertyChangedEventArgs.NewValue == true)
 {
 uiElement.MouseMove += UIElementOnMouseMove;
 }
 else
 {
 uiElement.MouseMove -= UIElementOnMouseMove;
 }

 }

 private static void UIElementOnMouseMove(object sender, MouseEventArgs mouseEventArgs)
 {
 var uiElement = sender as UIElement;
 if (uiElement != null)
 {
 if (mouseEventArgs.LeftButton == MouseButtonState.Pressed)
 {
 DependencyObject parent = uiElement;
 int avoidInfiniteLoop = 0;
 // Search up the visual tree to find the first parent window.
 while ((parent is Window) == false)
 {
 parent = VisualTreeHelper.GetParent(parent);
 avoidInfiniteLoop++;
 if (avoidInfiniteLoop == 1000)
 {
 // Something is wrong - we could not find the parent window.
 return;
 }
 }
 var window = parent as Window;
 window.DragMove();
 }
 }
 }

 public static void SetEnableDrag(DependencyObject element, bool value)
 {
 element.SetValue(EnableDragProperty, value);
 }

 public static bool GetEnableDrag(DependencyObject element)
 {
 return (bool)element.GetValue(EnableDragProperty);
 }
 }
}
</code></pre>
<h2>Step 2: Add Attached Property to any element to let it drag the window</h2>
The user can drag the entire window by clicking on a specific element, if we add this attached property:
<pre><code>&lt;Border local:EnableDragHelper.EnableDrag=&quot;True&quot;&gt;
 &lt;TextBlock Text=&quot;Click me to drag this entire window&quot;/&gt;
&lt;/Border&gt;
</code></pre>

This is all needed!

 {
 if (this.WindowState == WindowState.Maximized) // In maximum window state case, window will return normal state and continue moving follow cursor

As already mentioned by <a href="https://stackoverflow.com/users/5088793/fjch1997">@fjch1997</a> it's convenient to implement a behavior. Here it is, the core logic is the same as in the @loi.efy's <a href="https://stackoverflow.com/a/48304133/2858407">answer</a>:

<pre><code>public class DragMoveBehavior : Behavior&lt;Window&gt;
{
 protected override void OnAttached()
 {
 AssociatedObject.MouseMove += AssociatedObject_MouseMove;
 }

 protected override void OnDetaching()
 {
 AssociatedObject.MouseMove -= AssociatedObject_MouseMove;
 }

 private void AssociatedObject_MouseMove(object sender, MouseEventArgs e)
 {
 if (e.LeftButton == MouseButtonState.Pressed &amp;&amp; sender is Window window)
 {
 // In maximum window state case, window will return normal state and
 // continue moving follow cursor
 if (window.WindowState == WindowState.Maximized)
 {
 window.WindowState = WindowState.Normal;

 // 3 or any where you want to set window location after
 // return from maximum state
 Application.Current.MainWindow.Top = 3;
 }

 window.DragMove();
 }
 }
}
</code></pre>

Usage:

<pre><code>&lt;Window ...
 xmlns:h="clr-namespace:A.Namespace.Of.DragMoveBehavior"
 xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"&gt;
 &lt;i:Interaction.Behaviors&gt;
 &lt;h:DragMoveBehavior /&gt;
 &lt;/i:Interaction.Behaviors&gt;
 ...
&lt;/Window&gt;
</code></pre>

Add this to your Window style (I think properties are self-explanatory)

 &lt;Setter.Value&gt;
 &lt;WindowChrome GlassFrameThickness=&quot;0&quot; ResizeBorderThickness=&quot;3&quot; CornerRadius=&quot;0&quot; CaptionHeight=&quot;40&quot; /&gt;

My question is 2 fold, and I am hoping there are easier solutions to both provided by WPF rather than the standard solutions from WinForms (which Christophe Geers provided, before I've made this clarification).

First, is there a way to make Window draggable without capturing and processing mouse-click+drag events? I mean the window is draggable by the title bar, but if I set a window not to have one and still want to be able to drag it, is there a way to just re-direct the events somehow to whatever handles the title bar dragging?

Second, is there a way to apply an event handler to all elements in the window? As in, make the window draggable no matter which element the user click+drags. Obviously without adding the handler manually, to every single element. Just do it once somewhere?

Make WPF window draggable, no matter what element is clicked

我的问题是2折，我希望有更简单的解决方案，由WPF提供，而不是来自WinForms的标准解决方案( Christophe Geers提供，在我做出这一澄清之前)。首先，有没有一种方法可以在不捕获和处理鼠标单击+拖动事件的情况下使窗口可拖动？我的意思是窗口可以通过标题栏拖动，但是如果我设置了一个窗口没有标题栏，但仍然想要...
