I don't see how your posted method would ever have anything to do with view, insert, update, delete, if you're talking about that in regards to your backend database. And it shouldn't anyway .. databinding to UI controls is totally separate from the DataAccess, which should be done in a different layer (or at least a different class) than the UI.

You are databinding to a DataSource that is either a DataTable, or a class that implements an interface for databinding (I think it's IBinding, but don't quote me on that ... I never have used it, since I do all my databinding to DataTables), or a BindingSource. You are NOT databinding directly to the database.

What you have shown should work, assuming a couple of things when the control parameter you pass is a CheckBox.

1) The dataMember that you are passing is of a boolean datatype.
2) The propertyName that it is binding to is "Checked".

Now, that said, you *can* databind a CheckBox to a string instead of a boolean, however you'd have to sub-class the CheckBox and add Format and Parse event handlers to the Binding object. If you need to databind to a string datatype rather than a boolean, let me know and I can post an example CheckBox sub-class.
