KeyDownEvent Class

An event that occurs when a key is pressed while the RichEdit’s document has focus.

Declaration

export class KeyDownEvent extends RichEditEvent<KeyboardEventArgs>

Remarks

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

.NET Core Server Settings

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

@(Html.DevExpress().RichEdit("richEdit")
 .OnKeyDown("function(s,e) {
   console.log('The pressed key is: ' + e.htmlEvent.key);
 }")
 // ...

Client Settings

Use the keyDown property to specify the event handler.

const options = DevExpress.RichEdit.createOptions();
options.events.keyDown = function(s,e) {
  console.log('The pressed key is: ' + e.htmlEvent.key);
};

Runtime Settings

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

richEdit.events.keyDown.addHandler(function(s, e) {
  console.log('The pressed key is: ' + e.htmlEvent.key);
});

The event handler receives an argument of the KeyboardEventArgs type. The argument’s properties provide information specific to this event.
