change

Fired when the value of the widget is changed by the user.

The event handler function context (available through the keyword this) will be set to the widget instance.

Important: The event is not fired when the value of the widget is changed from code.

Event Data

e.sender kendo.ui.TextBox

The widget instance which fired the event.

Example - subscribe to the "change" event during initialization

<input id="textbox" />
<script>
    $("#textbox").kendoTextBox({
        change: function(e) {
            var value = this.value();
/* The result can be observed in the DevTools(F12) console of the browser. */
            console.log(value);
            // Use the value of the widget
        }
    });
</script>

Example - subscribe to the "change" event after initialization

<input id="textbox" />
<script>
    function textbox_change(e) {
        var value = this.value();
/* The result can be observed in the DevTools(F12) console of the browser. */
        console.log(value);
        // Use the value of the widget
    };
    $("#textbox").kendoTextBox();
    var textbox = $("#textbox").data("kendoTextBox");
    textbox.bind("change", textbox_change);
</script>

The change event fires only once the value of widget is changed and the widget itself is blurred out. You can add a custom events/methods by extending the existing functionality of the TextBox. How to add a keyup event to the TextBox is demonstrated in this article.
