You can set the Format property of the textbox to

"";"Yes";"No";""
"";"True";"False";""

if you want the -1 to display as Yes/True, 0 as No/False. This rather obscure
four-value format applies four different formats to numeric fields that are
positive, negative, zero and NULL respectively. Since a yes/no field is either
0 or -1, the other options aren't needed.
