I have a SL4.0 XamGrid bound to a collection of objects that is 2 levels deep.
I only want to display the top level in the grid. How do you get rid of that Expansion indicator?
You can explicitly define your columns and just leave out the properties that expose the sub collections. A great article on defining columns and column layouts is here:
