Hi Ajay Kumar,
According to your description, you'd like to drag and drop listviewitems between two listviews.
Here is my example for dropping items between listviews. You could add one imageList control to your form.
public Form1()
InitializeComponent();
this.listView2.AllowDrop = true;
this.listView1.AllowDrop = true;
this.listView2.View = System.Windows.Forms.View.LargeIcon;
this.listView2.DragDrop += new System.Windows.Forms.DragEventHandler(this.OnDragDrop);
this.listView2.DragEnter += new System.Windows.Forms.DragEventHandler(this.OnDragEnter);
this.listView1.ItemDrag += new System.Windows.Forms.ItemDragEventHandler(this.OnItemDrag);
private void Form1_Load(object sender, EventArgs e)
DirectoryInfo dir = new DirectoryInfo(@"D:\Material\Emoticons");
foreach (FileInfo file in dir.GetFiles())
try
this.imageList1.Images.Add(Image.FromFile(file.FullName));
catch
Console.WriteLine("This is not an image file");
this.listView1.View = View.LargeIcon;
this.imageList1.ImageSize = new Size(32, 32);
this.listView1.LargeImageList = this.imageList1;
this.listView2.LargeImageList = this.imageList1;
//or
//this.listView1.View = View.SmallIcon;
//this.listView1.SmallImageList = this.imageList1;
for (int j = 0; j < this.imageList1.Images.Count; j++)
ListViewItem item = new ListViewItem();
item.ImageIndex = j;
this.listView1.Items.Add(item);
private void OnItemDrag(object sender, System.Windows.Forms.ItemDragEventArgs e)
DoDragDrop(e.Item, DragDropEffects.Move);
private void OnDragEnter(object sender,
System.Windows.Forms.DragEventArgs e)
if (!e.Data.GetDataPresent(typeof(ListViewItem)))
e.Effect = DragDropEffects.None;
return;
var items = (ListViewItem)e.Data.GetData(typeof(ListViewItem));
if (items == null)
e.Effect = DragDropEffects.None;
else
e.Effect = DragDropEffects.Move;
private void OnDragDrop(object sender, System.Windows.Forms.DragEventArgs e)
ListViewItem items = (ListViewItem)e.Data.GetData(typeof(ListViewItem));
if (items != null)
this.listView2.Items.Add((ListViewItem)items.Clone());

If you have any other concern regarding this issue, please feel free to let me know.
