Remarks

The ValidationMode property specifies when the data form validates the user input. The following modes are supported:

LostFocus—the form validates a data field when an editor loses focus.
Input—the form validates a data field when its value changes.
Manually—the form validates data fields when the Validate() method is called. You can also call the Validate(String) method to validate a specific data field.

Note

The form also validates data fields when the Commit() method is called. If values are not valid, they are not committed to the underlying data object.
