The chances are that one of the events is firing: the DragEnter event.
But what gets dragged from the desktop is not text - it's files. So try this:

C#

private void textBox1_DragEnter(object sender, DragEventArgs e)
    {
    if (e.Data.GetDataPresent(DataFormats.FileDrop))
        {
        e.Effect = DragDropEffects.Copy;

        }
    else
        {
        e.Effect = DragDropEffects.None;
        }
    }

You should find the DragDrop event gets triggered now.
