INotifyDataErrorInfo.GetErrors Method
Gets the validation errors for a specified property or for the entire entity.
Namespace: System.ComponentModel
Assembly: System (in System.dll)
Parameters
- propertyName
- Type: System.String
The name of the property to retrieve validation errors for; or null or Empty, to retrieve entity-level errors.
This method returns an IEnumerable that can change as asynchronous validation rules finish processing. This enables the binding engine to automatically update the user interface validation feedback when errors are added, removed, or modified.
The return value can change to a different IEnumerable, or it can reuse a previously returned IEnumerable and change its contents. Any changes to the return value should raise the ErrorsChanged event, even if the return value implements INotifyCollectionChanged.
