grid with node-based columns

[mcgaffin]

I have an xml data source that I would like to display in a grid, but its columns are definied like:

<data>
<row>
<name />
<address />
</row>
</data>

instead of:

<data>
<row name="" address="" />
</data>

Can I make the grid component dynamically create columns from the subnode? By default, it only seems to work with attribute-based columns.

The structure of the xml data is dynamic, so I can't just create <gridcolumn> definitions with the appropriate datapath for each column.

Thanks,

david

What you want to do is to similar to what the basegrid function "inferColumns" does. In fact, you could override this method in your instance.

This answer doesnt make sence??

I am trying to work out the same thing.... Been searching and testing for hours...

How can I use the <node> xml instead of attribute xml, as described below?
