Ruben,do You mean a Border, or just changing the get-color itself ?
Frances,I think it is not supported, tested but nothing happens.
From DTPICKER.CH :
[ <oDTPicker> := ]
TDatePick():ReDefine( <nId>, bSETGET(<uVar>),;
<oDlg>, <nHelpId>, <nClrFore>, <nClrBack>, <oFont>, <oCursor>,;
<cMsg>, <.update.>, <{uWhen}>, <{uValid}>,;
[\{|nKey, nFlags, Self| <uChange>\}], <pic> )
[ <oTMPicker> := ]
TTimePick():Redefine( <nId>, bSETGET(<uVar>),;
<oDlg>, <nHelpId>, <nClrFore>, <nClrBack>, <oFont>, <oCursor>,;
<cMsg>, <.update.>, <{uWhen}>, <{uValid}>,;
[\{|nKey, nFlags, Self| <uChange>\}] )
Best Regards
