    According to the error messages, it seems that the viewstate has become "large". You can try fixing by chunking the viewstate into multiple fields using maxPageStateFieldLength in the web.config:

    <pages enableSessionState="true" enableViewState="true" enableViewStateMac="true" validateRequest

    For more information, please refer to the document:
