ASPxClientTextEdit.KeyPress Event
Occurs on the client-side when an end-user presses and releases a key while the editor has focus.
Declaration
KeyPress: ASPxClientEvent<ASPxClientEditKeyEventHandler<ASPxClientTextEdit>>Event Data
The KeyPress 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. |
Remarks
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 and releases a key while an editor has focus, the KeyPress event fires. This event can be handled to implement custom processing of a key being pressed and released.
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).
Note
The GetText method returns a string calculated based on a current editor’s value and the editor’s formatting settings (mask settings, the DisplayFormatString and EditFormatString properties, etc.). In this case, it is required to synchronize a text entered by an end user with an editor’s value before you use the GetText method. For example, if an editor loses focus, the editor automatically calculates (synchronizes) its value based on the entered text.
The GetText method returns an empty value or a previous editor’s text if you call this method before the editor calculates its a new editor’s value. For example, in the client-side UserInput, KeyDown, KeyPress, KeyUp event handlers, this method will return an empty value or a previous editor’s text. In this case, obtain an editor’s text directly from the editor’s input element:
function OnUserInput(s, e) {
var currentText = s.GetInputElement().value;
}
Example
This example demonstrates how the default browser processing of the Enter key, pressed while an ASPxTextBox has input focus, can be canceled with the help of a specific client method of a service ASPxClientUtils client object.
Note that the client script implementing the ASPxClientUtils object should be explicitly registered, to make this object available on the client:
protected void Page_Load(object sender, EventArgs e){
DevExpress.Web.ASPxWebControl.RegisterBaseScript(Page);
}
