ButtonClick

The server-side ButtonClick event occurs when the user clicks on a button, causing a postback.

The ButtonClick event handler receives two arguments:

1. The RadToolBar that contains the clicked button. This argument is of type object, but can be cast to the RadToolBar type.

2. A RadToolBarEventArgs object. This object has an Item property that you can use to access the button that was clicked.

Use the ButtonClick event handler to respond when the user clicks a button in the toolbar.

e.Item is of type RadToolBarItem . Therefore, you should first cast the e.Item object to RadToolBarButton type if you need to use the clickedbutton.
