Datagrid highlight row

[JontyMC]

I've seen some code for highlighting rows on a datagrid:

private void dataGrid1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e) 
{ 
  System.Drawing.Point pt = new Point(e.X, e.Y); 
  DataGrid.HitTestInfo hti = dataGrid1.HitTest(pt); 
  if(hti.Type == DataGrid.HitTestType.Cell) 
  { 
    dataGrid1.CurrentCell = new DataGridCell(hti.Row, hti.Column); 
    dataGrid1.Select(hti.Row); 
  } 
}

Trouble is, if you click a cell, hold down the mouse button and move off the row, it is still possible to edit the cell. I basically want a table where you single click to highlight, then double-click to open a new form to edit the data in that row. Surely must be a simple enough proposition?
