you need to write code to conforms to what IE expects.

void TreeView1ItemDrag(object sender, ItemDragEventArgs e)

  string[] stuff = new string[1];
  stuff[0] = @"http://www.google.co.uk"; // or e.Item.ToString() or however you've got your address in there
.
  //Create a new data object with the FileDrop type
  DataObject data = new DataObject(DataFormats.FileDrop, stuff);

  //And IE only wants Copy, it doesn't like move or whatever
  this.treeView1.DoDragDrop(data, DragDropEffects.Copy);

but I get an error saying that SelectedRows is a property but it is being used as a method.

foreach(DataGridRow myRow in myDataGrid.Rows)
{
    // do what ever you need to do with the row
}
