You need to bind to new collection of ITRDescriptionList, containing values, rather than directly to the Property itself.

As an example, try putting this in your Public Sub New() in your xaml.cs, under InitializeComponent()

Public Sub New()


    InitializeComponent()

    ITRDescriptionList = New List(Of ITRDescription)

    ITRDescriptionList.Add(New ITRDescription With {.ITRDate = Date.Today, .ITRDescription = "Test Description", .ITRUserName = "Joe Bloggs"})

    accordion1.ItemsSource = ITRDescriptionList

End Sub
