extending cxGrid with cxgridDbTableview

Question

I have created a component by extending cxGrid and added some required properties, I want to do same and add some extra functionalities to cxGridDBTableView, I tried extending the cxGridDBTableView and added properties, but I am not able to access those properties because when i drop my TdxdmGrid It is using the default cxgridTableView but I want to use TdxdmGridDbtableView,

I tried like below, But it is showing 2 different components and the view I designed is not linked to the grid.

How can this be achieved? Please help.

Thank you.

**Please** don't post source code as screenshots! SO has an "Insert code" functionality for that. — Uli Gerhardt, May 06 '19 at 06:36

You must register View with cxGridRegisteredViews, not with RegisterComponets()
If you want TDXPDMGridDBTableView as default View you must override TcxGrid.GetDefaultViewClass(). DefaultView is View which is created when you put your Grid to Form

  TDXPDMGrid = class(TcxGrid)
    ...
    protected
      function GetDefaultViewClass: TcxCustomGridViewClass; override;
    ...
  end;
...
function TDXPDMGrid.GetDefaultViewClass: TcxCustomGridViewClass;
begin
  Result := TDXPDMGridDBTableView;
end;
...
initialization
  cxGridRegisteredViews.Register(TDXPDMGridDBTableView, 'PDM Table');
...
finalization
  cxGridRegisteredViews.Unregister(TDXPDMGridDBTableView);
