RE: [flexcoders] Dymanic data/headers for DataGrid

Hey Dhiren,

Folling is simple example, where you can switch dataProvider of datagrid to
two different Arrays with different structure of objects..One with two
properties and other with three...

What do you mean by 2d Object array?

Does your array look like this:

var dp =        [
                        {Name:"Dhiren", Age:20},
                        {Name:"Abdul", Age:23}
                ];

Hi guys,

I'm sure this question has been asked before, however I can't find a 
suitable answer searching the forum.

What's the best way to display dynamic data resulting from a remote 
object in a DataGrid. I have no way of knowing the headers or the 
data which will result. I have it as follows now:

<mx:DataGrid id="dg3" dataProvider="{my_list.dataValues}">
</mx:DataGrid>

dataValues is a 2D Object array containing Strings and Doubles.

This has a few problems:

1. The data is displayed in opposite order. i.e. col 0 is displayed 
last and col n is displayed first.

2. I cannot display headers.

Any help would be appreciated. Thanks.

Dhiren
