OnGroupCalc event

VCL TMS VCL UI Pack

Hi,

 
In a TAdvStringGrid, I use OnGroupCalc event to set the Res variable to a min date of the grouped rows.
 
So in the header row of each group, I would like to display the value as a date format.
 
How can I do this ?
 
Thanks & regards
 
Régent.

I'd recommend to use OnGetDisplText for this.
