This method allows you to programmatically perform client-side validation of editors belonging to a specific container.
Note
If the containerID parameter is set to null, the method validates all/visible (under the validateInvisibleEditors parameter value) editors which belong to a specific validation group.
If the validationGroup parameter is set to null, the method validates all/visible (under the validateInvisibleEditors parameter value) editors located within the specified container.
If both the containerID and validationGroup parameters are set to null, the method clears all/visible (under the validateInvisibleEditors parameter value) editors on a page.
