Create column on execute time in TcxGrid like tDbGrid in delphi

Question

I use TcxGrid But I cant create fields on execution time because I have a pivot query and columns are variable

Can I fill cxGrid like tDbGrid?

Answer 1

I solved the problem like this

grdCevapDBTableView2.BeginUpdate;
grdCevapDBTableView2.ClearItems;
fillGridView(grdCevapDBTableView2,command);
grdCevapDBTableView2.DataController.CreateAllItems;
grdCevapDBTableView2.EndUpdate;

Answer 2

I like to use the TcxGrid.DataController.CreateAllItems method which creates all columns that exists in the datasource. It takes a boolean parameter with which you can decide wether to add all columns or only those missing.

Answer 3

Try something like this:

function TForm1.AddIntegerColumn(const ACaption, AName: string): TcxGridColumn;
begin
  Result := TableView.CreateColumn;
  Result.DataBinding.ValueTypeClass := TcxIntegerValueType;
  Result.Caption := ACaption;
  Result.Name := AName;
end;
