checkboxes bound to table not acting as expected

[kateryn]

I have a table to which I have used late-databinding to bind the textboxes and checkboxes on my windows form.

I use a bound combo box to that same table to display the correct info.

The textboxes are working perfectly in displaying the data from the correct row in the table when I select a different row using the combobox.

However, when I add a late-bound checkbox - my combo box ceases to work.
chkTowerStaked.DataBindings.Add("Checked", _
tResults, "Tower_Staked_YN&quot

The tower_staked_Yn field is defined as a bit in the SQL table.

Is there another setting on my form or in the control that I am overlooking?

Thank you
