Wpf 无法从Radcombobox获取所需的功能

我希望在cbo下拉列表中显示图像列表，在cbo的文本框中显示图像的名称，并将图像的路径存储回数据库

以下代码绑定cbo：

Dim logoImages As List(Of Logos) = New List(Of Logos)
Dim theLogoName As String = String.Empty
Dim theLogoPath As String = String.Empty

thisCombo.ItemsSource = Nothing

Dim listOfImages() As String = Directory.GetFiles("C:\XXX\logo", "*.*")

For i As Integer = 0 To listOfImages.Count - 1
theLogoPath = New Uri(listOfImages(i)).AbsolutePath
theLogoName = Mid(theLogoPath, 13)
logoImages.Add(New Logos() With {.logoImage = New Uri(listOfImages(i)), .logoName = theLogoName, .logoPath = theLogoPath})
Next

thisCombo.ItemsSource = logoImages

XAML：

下拉列表正确显示图像。我无法获取要显示在cbo文本部分的图像名称，也无法获取返回数据库的路径

---

有人能告诉我我做错了什么吗？谢谢

这是显示图像名称所需的。来自和的想法：

将SelectedValue用于数据库是存储回数据库的路径所需的
