Jim,

>That is exactly what I am trying to do: field the Format event. But I can't figure out how to do it using the mmDataGrid class. I can't find the binding to change it and I can't figure out how to set it up during the instantiation of the mmDataGrid.

Even though we have enhanced the data binding for Windows Forms controls, behind the scenes we are still using standard .NET data binding. That said, what you're trying to do may be best accomplished by enhancing the DataGridTextBoxColumn class. Check out this link:
