DBgrid Memo field autosizing on and off

VCL TMS VCL UI Pack

I am would like to turn autosizing of rows on or off.

grid.AutoSizeRows(false,4)
Now rows adjust to content of cells.
 
There are occasions where a more compact look is required
 
Haven't been able to figure out how to set rows to single line. That is no autosizing.

You can set it back to the desired row height with grid.DefaultRowHeight
