I use TcxGrid I have create fields on execution time because I have a pivot query and columns are variable
I filled my grid like theese codes
grdCevapDBTableView2.BeginUpdate;
grdCevapDBTableView2.ClearItems;
fillGridView(grdCevapDBTableView2,command);
grdCevapDBTableView2.DataController.CreateAllItems;
grdCevapDBTableView2.EndUpdate;
Now I want to get sum values from these columns. How can create summary footer on runtime?
