RadChat supports a number of client-side events that let you customize the behavior of the chat:
OnActionClick occurs when an action button is clicked inside an attachment template, or when a suggestedAction is clicked.
OnInitialize occurs when the RadChat starts initializing on the client-side, before the underlying Kendo UI Chat widget is initialized.
OnLoad occurs after the RadChat has been fully initialized on the client-side.
OnPost occurs when a message is posted to the RadChat control.
OnSendMessage occurs when a message is posted through the chat message box.
OnTypingEnd occurs when the user clears the chat message box, signaling that he stopped typing. The event is also triggered when the user submits the currenlty typed in message.
OnTypingStart occurs when the user starts typing in the chat message box. The event is fired only once, and not upon each keystroke.
