Group header row

Good afternoon,

there's a way to insert into a header group row one check box ?



I try with



for I := 1 to SG1.LastRow do

begin

    if SG1.IsNode(I) then

    Begin

        SG1.AddCheckBox(1,I,False,True);

    End;

end;



The check box is really drawed but i loose the rest of text ...

There is another way ??



Thanks



Daniele
