OnClientTextChanged

The OnClientTextChanged client-side event occurs when the text currently present in the input area is changed and RadAutoComplete has lost its focus.

The event handler receives two parameters:

1. The instance of RadAutoCompleteBox firing the event.

2. An eventArgs parameter containing the following method:

• get_text() - returns the text currently present into the input area.

important The OnClientTextChanged client-side event is fired only when the input type of RadAutoCompleteBox is set to " Text ".

This event is used in scenarios when operations need to be preformed to RadAutoCompleteBox right after the text in the input area has been changed.

<script type="text/javascript">
	function textChanged(sender, eventArgs) {
		alert("The text currently present in the input area of RadAutoCompleteBox is: " + eventArgs.get_text());
	}
</script>
