So you want to implement drag and drop functionality for the listview. I did a google search for c# drag and drop listview. I got this article from c-sharpcorner. Implementing Drag and Drop in ListView Controls . I guess this is all you'll need for your requirement. Try to make the article work first on a different project. Here's an additional listview drag and drop article from Microsoft. *Edit oops the fonts got big weird.

Hi Asela I'm assuming this is related to this thread . It may be that you don't need those calls which brings me down to this question. What do you want to accomplish here? Without explaining the code what do you want to happen? There's a chance that we could use a more simple code with your requirement just like with the other thread . Regards Jan

Jan Montano · Answer

GetItemAt() returns a ListViewItem  Over Here = this.listView2.GetItemAt(pt.X pt.Y); ListViewItem item = this.listView2.GetItemAt(pt.X pt.Y);
