Hello
I've a XML datafield contening this kind of XML data (see bellow)
<items>
<item>
<att1>abcd</att1>
<att2>efgh</att2>
</item>
<item>
<att1>ijkl</att1>
<att2>mnop</att2>
</item>
</items>

I want to render this part of XML in a data grid looking like :

att1 att2
abcd efgh Apply cancel
ijkl mnop Edit

What dataXpath should I use to perform this.
How can I do to have only the att2 columns to be editable?

Many thanks
