Hi,

I investigated the provided screenshots, however, I am not sure I completely understand what is the issue you are experiencing.

If you would like to have only one option selected (Yes/No) you might consider using RadioButton controls. This way you would not need to use additional code to keep only one option selected.

This said, would you elaborate in more detail what is the issue that you have? What are your requirements and what should be the expected result?
