Datagridview Checkbox Show value "F" as unchecked, "T" as checked

Hi folks,

I have a datagridView on my form.

One of the columns that is bound to either has "T" or "F". I want to use a DataGridViewCheckBoxColumn in the grid but when I try it,  I am getting error message:

System.FormatException: F is not a valid value for Boolean...Makes senese I suppose

Is there an easy way around this ?
