I have a listview control, in detail mode, and I am trying to implement
Drag-and-drop from it.
If I click on an item, I can then re-click and drag it, but if I just click
and drag, it doesn't work, because the item I clicked isn't selected until
the mouse-up event.

I tried turning on "hover selection" on the control, and it works to an
extent, but seems slow to keep up with the mouse, so often you don't then
drag the correct item.

What am I doing wrong? Should I not be accessing the selecteditems
collection for this?
Code snippet:

private void lstExcelHeaders_MouseDown(object sender, MouseEventArgs e)
{
   if (lstExcelHeaders.SelectedItems.Count != 0)
   {
       lstExcelHeaders.DoDragDrop(lstExcelHeaders.SelectedItems[0].Text,
DragDropEffects.All);
   }
}
