Nested AdvancedDataGrid

Flex them Grids! (AdvancedDataGrid as a subgrid with flat data)

A grid inside a grid is a common requirement; I thought. Yet, I scoured the internet for a solution and I couldn’t find it anywhere (…at least not something that could be done with “flat data”). The following is something I wanted to achieve.


Adobe LiveDocs show an example here http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7bf2.html where they put a chart in an itemrenderer. However they show this example with “Hierarchical” collection. Their data structure looks like:

   1: [Bindable]

   2:      private var dpHierarchy:ArrayCollection= new ArrayCollection([

   3:        {name:"Barbara Jennings", region: "Arizona", total:70, children:[  

   4:          {detail:[{amount:5},{amount:10},{amount:20},{amount:45}]}]},

   5:        {name:"Dana Binn", region: "Arizona", total:130,  children:[ 

   6:          {detail:[{amount:15},{amount:25},{amount:35},{amount:55}]}]},

   7:        {name:"Joe Smith", region: "California", total:229,  children:[ 

   8:          {detail:[{amount:26},{amount:32},{amount:73},{amount:123}]}]},

   9:        {name:"Alice Treu", region: "California", total:230, children:[ 

  10:          {detail:[{amount:159},{amount:235},{amount:135},{amount:155}]}

  11:        ]}

  12:      ]);      

However, this is almost never how one would get data from the server. We generally get a flat data-structure as ArrayCollection. The the trick would be to convert this flat structure into a Hierarchy of objects.

Take that Times-of-India

I read the Times of India almost every morning. I like to consume the news and the rest of the “masala”  with my “Cup’O Joe”. However, people running the newspaper’s electronic version seem to have forgotten that they are in the business of delivering news and not advertisements (…purely from a consumer point of view). I am aware there are ads everywhere, but nytimes.com, wsj.com, they do it “unobtrusively”.
Why don’t you try, TOI?

Adobe Flex 3 Certified (...at last)

I have been procrastinating for a long time. Every time I set a date for the exam, something came up, (...as it usually does); I promptly procrastinated. Blame the laziness (a programmer's best virtue). In that regard I am quite up there (where programming is concerned, of course).

30th July '10 was the day my stars aligned; I walked into a PearsonVue testing center nearby and I committed myself to the dreaded 9A0-082.

Well, here's my testimony and advice:
The exam was not that hard contrary to what many claim. I finished it in about 25 minutes and had lots of time to review the flagged questions. If you've covered LiveDocs, that's more than sufficient; for practice, Attest worked. I found I either knew the answer or I didn't. I didn't spend too much time pondering over each question (there isn't much to ponder). Maybe a few seconds to understand the code in the options.

If anyone needs any guidance, feel free to write; I'll gladly help.
