Hello everyone,

Please help me how to set my list-type CDF

when a checkbox is checked, I can change the value of list-type CDF.
when checkbox is unchecked, the list-type CDF is read-only.

Thank you in advance.

You can implement a table extension for the table where you added the CDF. For the CDF itself create the Is ReadOnly hook and return true or false depending on the checkbox value. Note that you need to be on at least ES10.5 to have this extensibility support.
