在Silverlight中从ItemDragEventArgs获取目标点

如何解决在Silverlight中从ItemDragEventArgs获取目标点

|| 如何从

ItemDragEventArgs

获取目的地？使用

Microsoft.Windows.DragEventArgs e

很容易：easy2ѭ XAML

<toolkit:PanelDragDropTarget AllowDrop=\"True\" ItemDroppedOnTarget=\"DragAndDrop_ItemDroppedOnTarget\">

后面的代码

private void DragAndDrop_ItemDroppedOnTarget(object sender,ItemDragEventArgs e)
{
   // how to get the destination Point here??
}

    

解决方法

        这看起来很像骇客，但它确实有效并且非常准确：

private Point _releasePoint;

public Grid()
{
   Grid.MouseLeftButtonUp += new MouseButtonEventHandler(Grid_MouseLeftButtonUp);
}

void Grid_MouseLeftButtonUp(object sender,MouseButtonEventArgs e)
{
   _releasePoint = e.GetPosition(Grid);
}

private void DragAndDrop_ItemDroppedOnTarget(object sender,ItemDragEventArgs e)
{
   // fires next and _releasePoint is already set
}
