C# WPF拖拽及；放下，德拉戈弗

我想将按钮从一个

Stackpanel

拖放到另一个

Stackpanel

。该实现仍然有效，但我希望在拖动事件期间将按钮作为视觉反馈附加到鼠标光标

我找了一整天的解决方案，但我只找到了使用

Canvas

的解决方案，而没有使用

Stackpanels

这是我的密码：

按钮.xaml

 <UserControl x:Class="LisaBeispiel2.Controls.ImageButton"

  Name="IB"
  AllowDrop="True">


<Grid>
    <Button Margin="3 0 3 3"
            VerticalAlignment="Top"
            HorizontalAlignment="Left"
            IsEnabled="{Binding IsButtonEnabled, ElementName=IB}">

您可以使用此事件并对其进行修改，使其与拖放事件一起工作。

您需要在某个父容器上安装装饰器。你可以把一块画布放进装饰物中，得到你想要的效果。谷歌搜索：wpf dragadorner

void StackPanel_DragEnter(object sender, System.Windows.DragEventArgs e)
{
     e.Effects = System.Windows.DragDropEffects.Copy;
}
