LostFocusEvent Class

An event that occurs when the control loses focus.

Declaration

export class LostFocusEvent extends RichEditEvent<EventArgs>

You can define the LostFocus event handler either at the server side, at the client side, or at runtime.

Use the OnLostFocus(String) method to specify the event handler.

cshtml

@(Html.DevExpress().RichEdit("richEdit")
 .OnLostFocus("function(s,e){ /* your custom actions */ }")
 // ...

Use the lostFocus property to specify the event handler.

javascript

const options = DevExpress.RichEdit.createOptions();
options.events.lostFocus = function(s,e) { /* your custom actions */ };

The lostFocus property provides access to the addHandler(handler), removeHandler(handler), and clearHandlers methods that allow you to dynamically add and remove event handlers.

javascript

richEdit.events.lostFocus.addHandler(function(s, e) { /* your custom actions */ });

The event handler receives an argument of the EventArgs type.
