如何在WPF ListView中获取光标下的Item

How to get Item under cursor in ListView ?

如何在ListView中获取光标下的项目？

For example when i move mouse cursor, i wish to get an item under it(cursor) and put its name to statusbar.

例如，当我移动鼠标光标时，我希望得到它下面的一个项目（光标）并将其名称添加到状态栏。

Actually i need method like GetItemAt(int x,int y) in WinForms.NET

实际上我需要在WinForms.NET中使用类似GetItemAt（int x，int y）的方法

Thanks!

谢谢！

You can try using the VisualTreeHelper.HitTest method. Something like this:

您可以尝试使用VisualTreeHelper.HitTest方法。像这样的东西：

    System.Windows.Point pt = e.GetPosition(this);
    System.Windows.Media.VisualTreeHelper.HitTest(this, pt);

public static object GetObjectAtPoint<ItemContainer>(this ItemsControl control, Point p)
where ItemContainer : DependencyObject
{
    // ItemContainer - can be ListViewItem, or TreeViewItem and so on(depends on control)
    ItemContainer obj = GetContainerAtPoint<ItemContainer>(control, p);
    if (obj == null)
        return null;

    return control.ItemContainerGenerator.ItemFromContainer(obj);
}

public static ItemContainer GetContainerAtPoint<ItemContainer>(this ItemsControl control, Point p)
where ItemContainer : DependencyObject
{
    HitTestResult result = VisualTreeHelper.HitTest(control, p);
    DependencyObject obj = result.VisualHit;

    while (VisualTreeHelper.GetParent(obj) != null && !(obj is ItemContainer))
    {
        obj = VisualTreeHelper.GetParent(obj);
    }

    // Will return null if not found
    return obj as ItemContainer; 
}
