How to get Item under cursor in ListView ?
For example when i move mouse cursor, i wish to get an item under it(cursor) and put its name to statusbar.
Actually i need method like GetItemAt(int x,int y) in WinForms.NET

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