editing bit columns

[Dean]

I'm trying to edit a table with a text columnand a bit column. The text
column works fine and the bit column displays the checkbox template column
ok but I can't seem to figure out how to get the selected value into my row
field the Updatecommand event. I'm trying to do the following:

private sub myGrid_UpdateCommand(byval........
..
..
myrow.textfield = CType(e.item.cells(0).controls(0), TextBox).text <--
works fine
myrow.bitfield = CType(e.item.cells(1).controls(0), boolean) < --value of
UI can't be converted to boolean


How can I get the value of the check box into the bit field?
Thanks,
Dean
