如何捕获将TDBGrid作为其父级的按钮的单击事件？

I have a small button I want to add to the top left corner of a Delphi TDBGrid component (in the header/title cells). I am able to place the button easily, but now the click event is not handled. I'm guessing the event is being caught by the grid. Any way I can force this specific event to go to the button instead? Note I still need the grid to handle click events for its title buttons like it currently does.I have a small button I want to add to the top
