Need lock for model and view?

They may access/modify data simultaneously.

For example, it's possible that the model is deleting data while the view is accessing deleted data. But with a lock, the view becomes slower, and it locked data frequently.

What's the proper way?

Are you using multiple threads?

Maybe.
Posting event to the UI thread seems a good solution.
