Borderstyle was already set to None. I can have the same combobox outside of the grid, and it displays the entire text without problems. The combobox in the grid remains the same size the entire time, but the entire right half of the text portion of the combobox is just missing. For example, I have 9 items listed in the combobox, all "Chemical 1" thru "Chemical 9". When the dropdown is selected, I see the full text of every item. When the item is selected, all I see is "Chemi ". I put the extra spaces in here to show that I have plenty of room in the combobox display area to show the full name. I'm totally at a loss as to why this is happening!
