An example of an AI chatbot conversation about WPF data binding validation techniques.
How can I implement data binding validation in WPF?
You can implement data binding validation in WPF by using the IDataErrorInfo interface or the ValidationRules class.
Can you explain how to use the IDataErrorInfo interface?
Sure! The IDataErrorInfo interface allows you to provide validation logic in your data model. You implement the Error and Item[] properties to return validation errors.
What about using ValidationRules? How does that work?
ValidationRules are used in XAML to define validation logic directly in your binding. You create a custom ValidationRule class and override the Validate method.
Are there any examples of custom validation rules?
Yes, you can create a custom validation rule by inheriting from ValidationRule and implementing your validation logic in the Validate method.
