Event Name	Components	Description
onChange	textbox datebox decimalbox doublebox intbox combobox bandbox	Event: InputEvent Denotes the content of an input component has been modified by the user.
onChanging	textbox datebox decimalbox doublebox intbox combobox bandbox	Event: InputEvent Denotes that user is changing the content of an input component. Notice that the component's content (at the server) won't be changed until onChange is received. Thus, you have to invoke the getValue method in the InputEvent class to retrieve the temporary value.
onSelection	textbox datebox decimalbox doublebox intbox combobox bandbox	Event: SelectionEvent Denotes that user is selecting a portion of the text of an input component. You can retrieve the start and end position of the selected text by using the getStart and getEnd methods.
onFocus	textbox datebox decimalbox doublebox intbox combobox bandbox button toolbarbutton checkbox radio	Event: Event Denotes a component obtained focus. Please note that event listeners execute at the server, so the focus at the client might have changed when the event listener for onFocus is called.
onBlur	textbox datebox decimalbox doublebox intbox combobox bandbox button toolbarbutton checkbox radio	Event: Event Denotes a component lost focus. Please note that event listeners execute at the server, so the focus at the client might have changed when the event listener for onBlur is called.
