Description

When wiring up (validationFailed) on IgxDatePicker, the handler appears to require an IDatePickerValidationFailedEventArgs type. However:

Importing the type from the package root fails because it is not exported:

// error: '"igniteui-angular"' has no exported member named 'IDatePickerValidationFailedEventArgs'. // Did you mean 'IgxTimePickerValidationFailedEventArgs'? 

Importing the type from an internal path (as found in older samples) forces a deep import:

import { IDatePickerValidationFailedEventArgs } from '@infragistics/igniteui-angular/lib/date-picker/date-picker.common'; 

which triggers an unrelated build error:

TS2307: Cannot find module '@infragistics/igniteui-angular/lib/dialog/dialog.component' or its corresponding type declarations. [plugin angular-compiler] src/app/button-enabled-dialog/button-enabled-dialog.token.ts:2:31 

This suggests the event-args type for the date picker’s validationFailed is either not publicly exposed

• igniteui-angular version: latest
• browser: all

Steps to reproduce

Demo Sample

1. Add a date picker with (validationFailed):
2. Implement the handler with the expected date-picker-specific args:
3. Try to import the args from the package root:
4. Observe the “not exported member” error.
5. Try to import from the internal path:
6. Observe the TS2307 module resolution error for .../lib/dialog/dialog.component.

Result

Errors. No public export for the date picker’s validationFailed event args.

Expected result

The validationFailed event should have a properly exported.
