bind two datasets together

[LarryLiang]

Hey guys,

Basically what I need to do is to bind two datasets together so they each have
a copy of the same data. Then I'll put a filter on one of them which will be
later served as the dataprovider of a combo box.

After I tried to bind the two datasets' dataproviders together in flash
authoring, at runtime, flash did not copy the data from one into the other one.
Then I tried to bind them together using actionscript by creating endpoints. it
still did not work.

Can anyone tell me if it's possible to bind two datasets together and if
possible, how?

Btw, what's the difference in concepts between the "items" property of a
dataset and the "dataprovider" property of the dataset. It seems that they hold
the same data as long as u do not use filters.


Thanks

I am not sure I understand your question. First, in Flex, the word "dataset"
has no specific meaning. What do you mean when you use the term? Second, the
word "bind" has a very specific meaning in Flex. Are you using the word in
that sense?

All data aware controls have a dataProvider property. For heirarchical
controls, the dataProvider is typically set to an object or XML. For
list-based controls the dataProvider is typically an array of objects. An
"item" is one of the array elements, an object.
