User Control values

Question

My Windows form has a user control which has a couple of windows controls including a gridview.
I am binding the gridview in the user controls load event. The grid view has a check box column
along with other data bound columns.I am trying to enable all the checkboxes in the checkbox column
in the grid. when the form is displayed I can see the checkbox column in the grid but cannot
see the selections of the checkbox. In debug I can see the values being set in the controls
load event but are being reset to null in the forms load event. I tried setting the controls values explicitly from
the form's load event but still cannot see the check box selections. Can you let me know
what I am missing.
