When I hand over focus with key TAB to ListView, ListView not select first item. 
How on it?

Answer:

We have two ListView components. First component with name ListView1 contains two 
events.


1   procedure TForm1.ListView1Enter(Sender: TObject);
2   begin
3     HookHandle := SetWindowsHookEx(WH_KEYBOARD, @MsgHook, 0, GetCurrentThreadID);
4   end;
5   
6   procedure TForm1.ListView1Exit(Sender: TObject);
7   begin
8     UnHookWindowsHookEx(HookHandle);
9   end;



Second component with name ListView2 is activate with procedure MsgHook.

10  
11  function MsgHook(Code: Integer; WParam: WPARAM; LParam: LPARAM): Integer; stdcall;
12  const
13    KeyTAB: Integer = 983041;
14  begin
15    if (Code = HC_ACTION) then
16    begin
17      if LParam = KeyTAB then
18      begin
19        frmMain.lsvCCM.SetFocus;
20        SendMessage(Form1.ListView2.Handle, WM_KEYDOWN, VK_DOWN, 1);
21  
22        Result := -1;
23        Exit;
24      end;
25    end;
26  
27    Result := CallNextHookEx(HookHandle, Code, WParam, LParam);
28  end;
