drag image from one listview to another listview

Drag&Drop in 6 Steps

Detect a drag as a combinatination of MouseMove and MouseLeftButtonDown
Find the data you want to drag and create a DataObject that contains the format, the data and the allowed effects.
Initiate the dragging by calling DoDragDrop()
Set the AllowDrop property to True on the elements you want to allow dropping.
Register a handler to the DragEnter event to detect a dragging over the drop location. Check the format and the data by calling GetDataPresent() on the event args. If the data can be dropped, set the Effect property on the event args to display the appropriate mouse cursor.
When the user releases the mouse button the DragDrop event is called. Get the data by calling the GetData() method on the Data object provided in the event args.

Drag:

<listview x:name="DragList" xmlns:x="#unknown"> PreviewMouseLeftButtonDown="List_PreviewMouseLeftButtonDown"
PreviewMouseMove="List_MouseMove"/>




private void List_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
// Store the mouse position
startPoint = e.GetPosition(null);
}




private void List_MouseMove(object sender, MouseEventArgs e)
{
// Get the current mouse position
Point mousePos = e.GetPosition(null);
Vector diff = startPoint - mousePos;

if (e.LeftButton == MouseButtonState.Pressed &&
Math.Abs(diff.X) > SystemParameters.MinimumHorizontalDragDistance ||
Math.Abs(diff.Y) > SystemParameters.MinimumVerticalDragDistance )
{
// Get the dragged ListViewItem
ListView listView = sender as ListView;
ListViewItem listViewItem =
FindAnchestor<listviewitem>((DependencyObject)e.OriginalSource);

// Find the data behind the ListViewItem
Contact contact = (Contact)listView.ItemContainerGenerator.
ItemFromContainer(listViewItem);

// Initialize the drag & drop operation
DataObject dragData = new DataObject("myFormat", contact );
DragDrop.DoDragDrop(listViewItem, dragData, DragDropEffects.Move);
}
}




// Helper to search up the VisualTree
private static T FindAnchestor<t>(DependencyObject current)
where T : DependencyObject
{
do
{
if( current is T )
{
return (T)current;
}
current = VisualTreeHelper.GetParent(current);
}
while (current != null);
return null;
}

Drop:
<listview x:name="DropList"> Drop="DropList_Drop"
DragEnter="DropList_DragEnter"
AllowDrop="True" />




private void DropList_DragEnter(object sender, DragEventArgs e)
{
if (!e.Data.GetDataPresent("myFormat") ||
sender == e.Source)
{
e.Effects = DragDropEffects.None;
}
}




private void DropList_Drop(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent("myFormat"))
{
Contact contact = e.Data.GetData("myFormat") as Contact;
ListView listView = sender as ListView;
listView.Items.Add(contact);
}
}
