In order to show "No Data" message above the DataGrid when there is no data in it we can use the following technique:

1. create a canvas and place the data grid on it
2. place also a HBox/VBox on that canvas and in it place a label with the message you want (I.E "no data")
3. Control visibility of the HBox by using binding with the DataGrid length

See code

How to draw Alternative Row Background in TileList?
TileList inherits from TileBase. TileBase has a function called "drawTileBackground".

How do we select the color for the background color of the tile? We can create a class that extends TileList and override this function in order to change this color.

So the story is like this. I was using a FLEX SWFLoader to load some external SWF files, these SWF files have some objects in them and when played the objects(in this case images) appear out of the border of the SWFLoader. It seams that the images expand out of the border and hide other GUI elements that are near the SWFLoader.

This short example is meant to demonstrate the usage of data binging in FLEX to invoke method calls. Copy the code to an editor to be able to use the line numbers that will be specified later

I am working on a project where i use a custom item renderer. This renderer is a VBox that contains a label and a List control.

In the examples that adobe provide on CheckBox itemRenderer/itemEditor the check box editor is not what i wanted

After some looking around , i found out that i didn't see an easy example on how to add images to Column Headers in Flex Data Grid

Well ,this is not too complected to do in Flex3

this article shows how to use 2 slider controls to create a single "Time Picker" control in Flex.

There is no time selection control available in flex, in this example we use a simple FLEX TextInput to create a Time Selection Control.

Some times you want to change the background color of a row inside a FLEX DataGrid. You usually want to do so in order to mark that row as an error or to make it out stand from the other rows.

This may have happen to you too, you work with Eclipse and suddenly it stops coping and pasting and it is very annoying

To temporarily solve the problem you can disable "Folding" in the Java Editor
Go to: Window-->Preferences-->Java-->Editor-->Folding and un-check the folding option

This should do the trick

In order to draw a line over a flex graph you can use a CartesianDataCanvas element.

A simple way to build a data provider for a flex tree is to use XMLList

This simple application will use XMLList to populate the data provider of the FLEX Tree.

Sometimes you need to call a function that is defined in your Flex application from the JavaScript code that wraps it.

In order to add a timer to Flex use the following code:

import flash.utils.Timer;
import flash.events.TimerEvent;

private function createTimer():void {
