  Hi,
  
  How to hide columns in cell detail form ?
  I would like to hide columns directly on the double click event.
  
  I find no examples.
  
  thanks

  Add fcxDetailGrid in uses.
  
  Hi.
  
  Standard code:
  
  procedure TfcxSliceDataZone.DblClick(X, Y: Integer);
  var
  DataPoint: TfcxDataPoint;
  begin
  DataPoint := PointToDataPoint(Point(X, Y));
  if Assigned(Grid.OnDataDblClick) then
  Grid.OnDataDblClick(Self, DataPoint.x, DataPoint.y)
  else
  begin
  if not Assigned(FDetailColumns) then
  FDetailColumns := TfcxCubeDataColumns.Create;
  ShowDetails(Grid.Slice, Grid.PaintStyle, Point(DataPoint.X, DataPoint.Y), FDetailColumns, Grid);
  end;
  inherited;
  end;
  
  
  Example of OnDataDblClick event:
  SliceGrid1DataDblClick(Sender: TfcxSliceDataZone; XAxisIndex, YAxisIndex : Integer)
  var
  DetailColumns: TfcxCubeDataColumns;
  NeedHideItemIndex: integer;
  begin
  DetailColumns := TfcxCubeDataColumns.Create;
  DetailColumns.Update(Sender.Grid.Slice.Cube);
  NeedHideItemIndex := 0; //!!!! Set index of field to hide
  DetailColumns.AbsItems[NeedHideItemIndex].Visible := False;
  ShowDetails(Sender.Grid.Slice, Sender.Grid.PaintStyle, Point(XAxisIndex, YAxisIndex), DetailColumns, Sender.Grid);
  end;
