XML refresh

Question

I'm loading data from an XML file into a xml connector -->
into a dataset --> into a datagrid components. The datagrid is
editable so the user can change values in it etc.
I want the user to be able to re-set the datagrid to its
original state at the click of a button. I was using
XmlConn.trigger(); method to do this - this means re-loading all
the xml data which can take a few seconds and is annoying if you
want to do this multiple times.
I'm not sure if this is correct but to my knoledge: When you
make changes to the dataGrid it doesnt make the change to the
loaded xml (i tested this by doing xmlcon.results after each change
to the datargid).
Is there a way of just refreshing the datagrid with the
already loaded xml data rather than having to reload the data each
time?

Answer 1

I tried doing this:
var test = items_ds.dataProvider;
items_ds.dataProvider = test;
trace(items_ds.dataProvider);
And it seems to do something: it pauses a split second as if
loading data, it resets the item in focus on the datagrid to the
first item, but it doesnt seem to refresh the data back to the
original values.
I tried using:
items_dg.redraw();
after, but it made no difference.
This is so annyoing, the data is there, i know this, i just
cant get it to refresh in anyway and the documentation on this is
so vague.
Anyone got more ideas?
