Point clientPoint = dataGridView1.PointToClient(new Point(e.X, e.Y));
DataGridView.HitTestInfo info = dataGridView1.HitTest(clientPoint.X, clientPoint.Y);
if (info.Type == DataGridViewHitTestType.Cell)
{
if (dataGridView1.Columns[info.ColumnIndex].HeaderText == "Name")
dataGridView1.Rows[info.RowIndex].Cells[info.ColumnIndex].Value = item;
MessageBox.Show("data is " + item);
}

}
private void dataGridView1_DragEnter(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent(typeof(System.String)))
e.Effect = DragDropEffects.Copy;
