# ButtonClicking
The client-side **ButtonClicking** event is raised when user clicks on a button orstep before the **RadWizard** responds to the click. You can handle this event in case you want to prevent the click.This article discusses the objects of the control's **ButtonClicking** event and shows an example of how to retrieve properties when the event occurs (**Example 1**).
To handle this event, simply write a JavaScript function that can be called when the event occurs. Then assign the name of this function as the value of the the **OnClientButtonClicking** property.
The client-side **ButtonClicking** event handler receives two arguments:
* Sender—the [RadWizard object](https://www.telerik.com/products/aspnet-ajax/documentation/controls/wizard/client-side-programming/wizard-object) that fired the event.
* Event arguments—an event arguments object that exposes the following methods:
