How to use WPF Data Binding with an MVVM Model to Populate a StackPanel with Custom Controls

Question

I have a hierarchy of data that looks like this:

• Policy
  • Check
    • Action
    • Action
    • Action
  • Check
    • Action
  • Check

For each Policy/Check/Action, I have a custom control built in WPF. I have been programmaticly adding new instances of my controls to containers in the parent control. (IE. When a user clicks the "Add Check" in the Policy control, I will do a MyPolicy.StackPanelChecks.Children += new CheckControl() ). I am converting to an MVVM model and am trying to use data binding to populate this StackPanel (and don't want to embed DataTemplates into my code, especially with a hierarchy of data model objects).

What is the best known way to do this?

Answer 1

This looks more like a TreeView than a StackPanel to me.

In MVVM you bind to the hierarchy and define HierarchicalDataTemplates for each node type.
