Your WPF application needs to display a list of employees and their performance ratings from a database. Explain how you would implement data binding with sorting and filtering capabilities.

To implement data binding with sorting and filtering capabilities in a WPF application, you can use CollectionViewSource along with the ICollectionView interface. CollectionViewSource provides a wrapper around your data source, while ICollectionView offers sorting and filtering functionalities. You can bind your employee data to a CollectionViewSource and then apply sorting and filtering criteria through the ICollectionView interface, allowing users to interactively sort and filter the employee list in the UI. This approach provides a flexible and efficient way to handle sorting and filtering requirements while maintaining a clean separation between UI and data logic. The other options may not offer built-in support for dynamic sorting and filtering or may require more manual coding effort.
