However, it is currently internal as it is used for the Angular JS integration. There is another event called which is triggered when the state of the validation is changed (either for the single input element for the the entire form). The 'change' event doesn't fire when the value is not changed.

Introduction This article shall address the use of the error provider control in Win Forms application development.
The error provider control is most useful in displaying errors associated with data entry tasks on a Windows form.
As a result of the test, the error provider control is configured; if the string is empty, the error provider is associated with the text box control and the error provider's control is set to display "This field must contain text".
If the string is not empty, the error provider is set to display nothing; this disables the error provider as applied to that control.
Normally one would write a custom validation method for each of the controls and test the control's content against that validation method whenever that specific control is validated.
If the string is not empty, the error provider icon will not appear and there will be no tooltip.
The method used to validate the control is as follows: This simple method is configured to return a boolean value; if the text box control contains text, the function will return false and no error provider indication will be shown on the form.
The result is that, whenever the text box control is validated, the test will execute and, if failed, the error provider icon will be displayed.
If the user hovers the cursor over the error provider's icon, the tool tip text will be displayed.
