    <p>The absolute best way to do this is create your hierarchical tree in your data model. So for every node that has children, if you have a selected property, you would also modify the selected property on those children. This way, your ADG is merely a view of the state of the data. You then tie the change event of the checkbox to this selected property.</p> <p>[Edit to show Tree sample]</p> <p>So similar to XML, you're data structures can have a tree leaf/node paradigm For Example (psuedo code):</p> <p>A tree of "People":</p> <pre><code>var gf:Person = new Person(); gf.name = 'Frank'; var gm:Person = new Person(); gm.name = 'Elise'; var c1:Person = new Person(); c1.name = 'Mary'; var c2:Person = new Person(); c2.name = 'Frank Jr'; var c3:Person = new Person(); c3.name = 'Sam'; var couple:PersonGroup = new PersonGroup(); couple.relation = [gm, gf]; couple.children = [c1, c2, c3]; //now you add another 'married PersonGroup to child one, and their children' </code></pre> <p>So since you have a 'children' property the HierarchicalData knows how to work with this, but their is a field which allows you to set it to something else if your 'node' is named something else.</p> <p>So to extend this each 'Person' would have a property that is 'selected, enabled, alive, whichever', and that property needs to be a setter, which then modifies that property also present in it's children. In this way the state of your data is always preserved in your data model, and the ADG just happens to be the current view that you use to display that representation.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
