问题
I have a ListBox which is made up of Grid Items in Multiple SelectionMode in Silverlight 3.0.
When I use ListBox.SelectedIndex it only returns the first item which is selected.
I would like to be able see all of the selected items such that it would return all of the selected item indexes' such as; 2, 5, and 7, etc.
Any help?
Cheers,
Turtlepower.

You can find the selected indexes by iterating through SelectedItems
and finding the objects in the Items
property, like this:
List<int> selectedItemIndexes = new List<int>();
foreach (object o in listBox.SelectedItems)
selectedItemIndexes.Add(listBox.Items.IndexOf(o));
Or if you prefer linq:
List<int> selectedItemIndexes = (from object o in listBox.SelectedItems select listBox.Items.IndexOf(o)).ToList();
