_______________________________________________________________________

The above code adds controls programmatically with values driven from the
database. When the user hits the
save button, I am having a hard time to pull out the checkbox values
designed programmatically at runtime.
How do I pull out the checkbox values in the btnSaveRoleDesig_onclick event?
If I try to write response.write(chkRoleDesigval.checked) or
chkRoleDesigval_0.checked in the onclick event,
it gives the error message that 'chkRoleDesigval or chkRoleDesigval_0 is not
declared'.
Any ideas on how to grab the checkbox values which are designed in the Page
Load event?
Thanks,
Uma

Try to look into the CheckboxList Control. This may help you bind the data
instead of generating the checkboxes at runtime.
