How do I get a datagrid to register a data change from a custom control cell (combobox)?

How do I get a datagrid to register a data change from a custom control cell (combobox)
I've got a Windows Application with a Windows Form Datagrid that has a custom combobox column. When the user clicks on a new row in the datagrid and tries to select or enter a new value in the combobox, the datagrid doesn't seem to register the change, so if the user tabs through the columns and onto the next row, the data is cleared and not saved

Does anyone have any insight into how to register a change in the datagrid when my combobox changes?
