Code:
include '%fasminc%\Win32ax.inc'
include '%fasminc%\macro\if.inc'

IDD_DLG1 equ 1
BTNEXIT equ 1000
IDC_GRP1 equ 1001
EDITTEXT equ 1002

main:
        invoke GetModuleHandle,0
        invoke DialogBoxParam,eax,1,0,DlgProc,0 
        invoke ExitProcess,0

proc DlgProc,hWnd,uMsg,wParam,lParam

.if [uMsg]=WM_CLOSE
        invoke EndDialog,[hWnd],1
.elseif [uMsg]=WM_COMMAND
        mov eax,[wParam]
        .if ax=BTNEXIT
                push [hWnd]
                call ExitProg
        .endif
.endif
xor eax,eax
ret

endp

proc ExitProg,hwnd
        invoke MessageBox,[hwnd],"Exit?","Dialog Test",MB_YESNO
        ;.if eax = IDNO  ;IF I UNCOMMENT CONDITIONS LIKE THIS THE DIALOG WON'T SHOW ANYMORE
        ;       ret                      ;WHAT'S WRONG? IT SEEMS THAT WHEN I ADD MORE CODE THE DIALOG WON'T SHOW
        ;.endif
        invoke EndDialog,[hwnd],1
        ret
endp

end data

.end main

I changed to this and worked:
Code:
include '%fasminc%\Win32ax.inc'
include '%fasminc%\macro\if.inc'

IDD_DLG1 equ 1
BTNEXIT equ 1000
IDC_GRP1 equ 1001
EDITTEXT equ 1002

main:
        invoke GetModuleHandle,0
        invoke DialogBoxParam,eax,1,0,DlgProc,0 
        invoke ExitProcess,0

proc DlgProc,hWnd,uMsg,wParam,lParam

.if [uMsg]=WM_CLOSE
        invoke EndDialog,[hWnd],1
.elseif [uMsg]=WM_COMMAND
        mov eax,[wParam]
        .if ax=BTNEXIT
                push [hWnd]
                call ExitProg
        .endif
.endif
xor eax,eax
ret

endp

data resource from 'test.res'
end data

proc ExitProg,hwnd
        invoke MessageBox,[hwnd],"Exit?","Dialog Test",MB_YESNO
        .if eax = IDNO  ;IF I UNCOMMENT CONDITIONS LIKE THIS THE DIALOG WON'T SHOW ANYMORE
              ret                      ;WHAT'S WRONG? IT SEEMS THAT WHEN I ADD MORE CODE THE DIALOG WON'T SHOW
        .endif
        invoke EndDialog,[hwnd],1
        ret
endp

.end main
    

Why?

If you end data - the assembler doesn't implicitly state that the next is .code section, but if you move your data section to the very end - the code section is contiguous.

it's recommended to preserve main registers in DlgProc (ebx,esi,edi)

it's required, not recommended. But he doesn't seem to change them anywhere
