Couldn't you just have two columns in the grid, one beside the other? If not, what you may want to try is create a container class and place a textbox and command button in it, align as needed. Then you can add this container to the grid column. Be sure to update the controlsource for the textbox used to display whatever value is needed.

One drawback to this approach is that a container in a column looses the ability to scroll the grid with the arrow keys. You have to go through hoops to control this. It requires code in the containers textbox to check for arrow keys, issue a respective skip +/- and/or Grid.DoScroll() method. Then you have to issue a direct setfocus to the same object name so the new record would receive the focus on whatever the new row would be.
