You can loop through and assign the property to each object.

for each( var item:Object in dpHierarchy ) {
trace(item.Year); // null
item.Year = 2008;
trace(item.Year); // 2008
}

Dynamic objects can have properties assigned at runtime.

hi.. s this works fine..

Any idea how to make item name dynamic..
something like..

private function updateDP():void {
for(var i:int=0;i<10;i++)
{
arr[0].Year = "2008"; /// How to add that 'i' value over here?
}
}

i wanna add Year1, Year2, Year3 --------- like this...
is its possible??

thanks in Advance

Just a kindly word of advice...

I'm not sure of your exact purposes, but it seems like you are trying to turn a property into a variable. Why the extra number at the end? It seems like this would needlessly complicate things.

hi thanks for advice..

In my current project content in array get generated dynamically at runtime.
so i need to add content to arraycolelction at runtime.

And i am not going to use "Year" over there. just for example am using that word.
