title: How do I get screen coordinates of the DBGrid cell
body: <p>I want to show popup button or fancy message (with coloured background, etc) just under right-bottom corner of particular cell of the current row. </p>
  
  <p>For now I only figured how to get grid coordinates:<br>
  x = DBGrid.DataSource.DataSet.RecNo<br>
  y = DBGrid.Columns[index]</p>
  
  <p>There is also TCustomGrid.CellRect, which would do what I want, but it's protected and I don't want to inherit and create another component class.</p>
  
  <p>One crazy workaround I can think of is to save TRect-s in onDrawColumnCell event to some array.</p>
  
  <p>So, what do you think ?</p>
  
  <p><strong>EDIT</strong><br>
  How do I get screen coordinates of, say, second cell in the current row ?</p>
