Specifies the name of the webroutine that is executed when the checkbox is clicked. (The name of the WAM containing the webroutine is specified in the on_click_wamname property.)

Note: It is not good user-interface design practice to initiate actions from the click of a checkbox. Devices such as a push button, menu item or anchor (hyperlink) should be used to accomplish this.

Default value
