Android validating input data
The following code example shows how validation occurs after a property change: This method retrieves the property to be validated, and attempts to validate it by calling the Try Validate Property method.
If the validation results change, for example, when new validation errors are found or when previous errors have been corrected, then the Errors Changed and Property Changed events are raised for the property.
Providing that validation succeeds, page navigation occurs, otherwise validation errors are displayed.
