ASPxClientTextEdit.KeyDown Event

Occurs on the client-side when an end-user presses a key while the editor has focus.


KeyDown: ASPxClientEvent<ASPxClientEditKeyEventHandler<ASPxClientTextEdit>>

Event Data

The KeyDown event's data class is ASPxClientEditKeyEventArgs. The following properties provide information specific to this event:

Property Description
htmlEvent Gets a DHTML event object that relates to the processed event.


The editors’ client-side functionality provides the ability to respond to key presses and releases made by end users. Each time an end-user presses a key while an editor has focus, the KeyDown event fires. This event can be handled to implement custom processing of the pressed key.

Using the ASPxClientEditKeyEventArgs.htmlEvent property of the event’s argument, you can obtain the necessary information related to the pressed key (such as its key code, the modifier key pressed, etc).

The GetText and the GetValue methods can return an incorrect (empty or previous) value in the client-side UserInput, KeyDown, KeyPress, and KeyUp event handlers when you apply a format, mask, or null text settings to a text editor.

In this case, obtain the editor’s text from the editor’s input element:

function OnKeyDown(s, e) {  
    var currentText = s.GetInputElement().value;  

For more information refer to the following Support Center ticket: ticket.


  • Built-in editors within the grid’s Filter Row do not raise the client-side ValueChanged, UserInput, and KeyDown events because these editors apply internal filter mechanisms.


This example illustrates how to emulate the Tab key using the Enter key.
