Delphi 5:

If DragMode is dmAutomatic I cannot select a row anymore.
If DragMode is dmManual the OnStartDrag isn't fired anymore.
What basic steps have to be taken to drag a row in a TDBGrid?

If DragMode = dmManual you need to call the grid's BeginDrag method to
initiate dragging.

which means that I have to watch OnMouseDown and start
a timer or watch for mouse movement?

I have implemented Drag&Drap with a tree control and
all I had to do was to but BeginDrag into the OnStartDrag
event (with DragMode=dmAutomatic, of course). This procedure
doesn't work with a table grid and my only explanation is
that this is a bug.

BeginDrag takes a parameter which tells it whether dragging should
start immediately. No need to monitor the mouse yourself - BeginDrag
does this for you.

I know about BeginDrag's parameter but where could I call
BeginDrag? OnMouseDown of the TDbGrid isn't fired when I
click on a row that contains data. It's only fired when
I click on an area of the grid that doesn't contain rows.
I used to start dragging by implementing the OnStartDrag
event and execute BeginDrag there. But OnStartDrag is only
fired when I set DragMode to dmAutomatic. If I set it to
dmAutomatic, I cannot select a row anymore. One setting
excludes the other, that's a neverending circle...
I'm really stuck with this problem, would you mind telling me
when and where to execute TDBGrid.BeginDrag?

You can try creating a TDBGrid descendant and override the MouseDown
method.
