Dynamically creat controlls / components

[Amun-Rah]

I have a Problem regarding the dynamic construction of a view. When i dynamically create controls (via code) in my view (e.g. IWCGJQTreeView) the treeview is not displayed. It is also not existent in the resulting HTML. When i create the same control with the delphi design editor is is correctly displayed. Is there something that needs to be done adittionally to enable the dynamic construction?

Hi,
You have to check if you gave a name and a parent to your component

Code: Select all

 
  Tv:=TIWCGJQTreeView.Create(Self);
  Tv.Parent:=RegionTests;
  Tv.Align:=alclient;
  Tv.Name:=CGFindUniqueComponentName(RegionTests,'tv_');
  for I := 0 to 9 do
  begin
    with Tv.TreeNodes.Add do begin
      Caption:=Format('Node %d',[i]);
    end;
  end;

Hi Amun-Rah,

If you are creating on some async Event, you need use AjaxReRender function.
Check the forum for more information.

Best Regards.
