Thanks for the reply, Tracy, about the ItemRenderers.
+1 on the htmlText warning. I've used the htmlText of the TextArea in an
AIR app, which I'm converting from local DB to webservice mode now. The
html rendering in Flex of the sort of html markup example I gave below
is better than bad but is far from rich. Adobe gets a very low passing
grade from me on its htmlText + CSS rendering in Flex. I don't need
typographic control (kerning, ligatures, etc) but I do want support for
basic CSS-- I could never get padding and margins to work. Font-family,
bold, italics, font-size do work.

Be aware that htmlText only renders a small subset of html tags.

*Subject:* [SPAM] [flexcoders] rendering HTML markup in AdvancedDataGrid
I am considering using an AdvancedDataGrid in hierarchical mode but am
not sure it can do what my app needs to do, or if it can, whether the
approach will be efficient--execute quickly and use up a lot of memory.
I haven't worked with the AdvancedDataGrid before.
The grid will look like this:
[v] Category A
[v] Title 1
* passage one blah blah blah
* passage two
[v] Title 2
[v] Title 3
.
.
.
[v] Title n
[v]Category B
[v] Title 1
[v] Title 2
[v] Title 3
.
.
.
Title n
etc
etc
When the user clicks on a Title node to expand it, some passages
excerpted from the corresponding document would be fetched from the
database, already formatted as HTML like this:
span class='foo'this is an excerpt span class='abc'100 to
1000/span characters in length/span.
A style sheet must control how the css classes in the passage excerpts
are rendered. The grid might have as many as 100 rows, and each row
could contain a couple of paragraphs of html text. Up to 1K each, but
more typically around 100-200 characters.
If I create an item-renderer using TextArea, will 100 TextAreas be
created if the grid has 100 Title rows even if only 3 titles are
expanded by the user? Or are the item renderers created only for the
rows that actually get expanded and displayed? Is there another way to
render HTML markup in the ADG?
Thanks
