I mean when you show the textdraw, create a timer using SetTimerEx, that hides the textdraw and shows the dialog.
Example:

pawn Код:

public OnPlayerConnect(playerid)
{
    TextDrawShowForPlayer(playerid, textdrawname);
    SetTimerEx( ... );
}

forward TimerName(playerid)
public TimerName(playerid)
{
    TextDrawHideForPlayer(playerid, textdrawname);
    ShowPlayerDialog(playerid, ... );
}
