+# Events Overview
+
+This article lists the clients-side events of the **RadSpreadsheet** and how to use them. Apart from the OnClientChange event, all other events are available as of R3 2019.
+
+All events follow the MS AJAX client events convention and receive two arguments:
+
+1. `sender` - the [RadSpreadsheet]({%slug spreadsheet/client-side-programming/overview%}) instance that raised the event
+1. `event arguments` - event-specific data provided to the developer
+
+**RadSpreadsheet** is a wrapper over the Kendo UI Spreadsheet widget and so it exposes the [client events](https://docs.telerik.com/kendo-ui/api/javascript/ui/spreadsheet#events) and data it does. You can find a list below.

+To get some intellisense inside the event handlers and check what methods are available in the arguments and values they contain, the browser's developer tools can be used. Here is a blog post article that shows one way to do it: Improve Your Debugging Skills with Chrome DevTools, section [Get IntelliSense for the Client-Side Object](https://www.telerik.com/blogs/improve-your-debugging-skills-with-chrome-devtools#get-intellisense-for-the-client-side-object).
