Hi,

Can you please help how to validate the currency in the textinput...
For example when the user type the amount as 2T then amount should be converted to 2,000.00.

Below is the code:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
			   xmlns:s="library://ns.adobe.com/flex/spark" 
			   xmlns:mx="library://ns.adobe.com/flex/mx" 
			   minWidth="955" minHeight="600" xmlns:curr="*">
		<curr:CurrencyTextInput/>
	</s:Application>

CurrencyTextInput.as

package {
	import flash.events.KeyboardEvent;
	import mx.controls.TextInput;
	import mx.formatters.NumberFormatter;
	

	public class CurrencyTextInput extends TextInput
	{	
		override protected function keyUpHandler(event:KeyboardEvent):void
		{
			super.keyUpHandler(event);
			
			if( text.length == 0 )
			{
				return;
			}

			var numberString:String= text;
			
			if(numberString.charAt(numberString.length -1) == "k" )
	{
				
				numberString=numberString.substr( 0, numberString.length - 1 );
				var number:Number=Number(numberString);
				
				if(number>=1 || number<=1)
				{
					super.text=(number*1000).toString();
					var result:String=super.text;
             					valResult(result);
					validateNow();
					textField.setSelection(super.text.length,super.text.length);
				}
			}
			
			}			
		
	
	public function valResult(result:String):void
		{
			 var formatter:NumberFormatter = new NumberFormatter();
			 formatter.precision = 2;
			super.text=formatter.format(result);
		}
		
		
	}
	}
