StringGrid.OnSelect

Why does clicking on a StringGrid cell when the DragMode is set dmAutomatic not call the OnSelect event? Instead I noticed that it calls the StartDrag event.  I want the StringGrid to allow the selection of a cell as if the DragMode was set dmManual, and when the the mouse button is held down to begin a drag of the StringGrid cell's object.  Many thanks.

In the mousedown event of the stringgrid do this...

if (Button = mbLeft) then
    StringGrid1.BeginDrag (false) ;

Please look at help for impact of BeginDrag parameters. Very important.
Then in the target control use the dragover and dragdrop method to handle your drop.

Hope this helps.

Thankyou RickJ for replying. I've tried your suggestion but the StringGrid still doesn't call the On Select event.

I dont think I am clear in what you are trying to do.
My comment was assuming that you would use dmManual.
But on reading your comment again, I see that you still want to use dmAutomatic?
And make onselect execute for dmAutomatic?
Why not use dmManual instead of dmAutomatic?
Just trying to get a picture of what you are actually trying to do.

Thanks
Rick.
