Question

I have a listbox to which I have bound the data context to an object. This object has a number of properties some of which will have a particular attribute.

What I want to do from this is to have the items source set to the properties of the object but to only display those properties that have a particular attribute set.

Can anyone help with where I would start on this?

Answer 1

You could use LINQ and reflection to get the values of the properties which have that attribute set:

Class1 class1 = new Class1 { Name = "Sam", DOB = DateTime.Now, SSN = "123" };

MyListBox.ItemsSource = from p in typeof(Class1).GetProperties()
                        where p.IsDefined(typeof(Att), false)
                        select p.GetValue(class1, null);

Name and DOB are marked as [Att] in my test, and their values are added to the ListBox. SSN is not.
