title: How to make the TScrollBox automatically scroll when DragMode is dmAutomatic?
body: <p>I have a ScrollBox in which I have a GridPanel in which I have Buttons.
  I set DragMode to dmAutomatic for all buttons so I can move the buttons around (drag and drop).</p>
  
  <p>But I have a problem: because the GridPanel is larger than the ScrollBox, the ScrollBox has the vertical scrollbar visible. I want to make the ScrollBar to automatically scroll down so I can drop a bottom from the visible (top) rows into the inaccessible rows at the bottom (this is typical behavior for all Windows programs, right?)</p>
  
  <p>I have simple code that is doing this: In MouseMove I detect when the mouse is getting close to the bottom of the ScrollBox and I adjust ScrollBox.VertScrollBa.Position to scroll down. This works ONLY if I am NOT in "drag and drop" mode (if I am not dragging a button).</p>
  
  <p>If I start a drag and drop operation <a href="https://stackoverflow.com/questions/14516629/onclick-and-mousedown-not-working-when-using-dragmode-dmautomatic">NO mouse events are fired</a>.</p>
  
  <p>What can I do to receive MouseMove event even if I am in "drag and drop" mode?<br>
  A solution would be not to use dmAutomatic and implement my own drag and drop alternative (based on mousedown, mousemove, mouseup). Is these a quicker fix? </p>
