    <p>This question is a follow-up to one I asked and got answered here: <a href="https://stackoverflow.com/questions/8636128/how-to-display-xps-document-using-a-selected-combobox-item">How to display XPS document using a selected combobox item</a></p> <p>I've created a WPF app using VB 2010. I set the comboboxitems via the XAML. However, I can't seem to figure out how to set the value of each item to a file path.</p> <p>The objective is for a user to be able to select an item from a drop-down list, then that selection opens an XPS file in the DocumentViewer. The code below was provided to me by COMPETENT_TECH (thanks) to read and display the value of the selected comboboxitem in the DocumentViewer.</p> <p>The path to the files I want opened is C:\folder\file.xps</p> <pre><code>Private Sub Button4_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button4.Click Try Dim sFileName As String sFileName = DirectCast(ComboBox1.SelectedValue, String) If Not String.IsNullOrEmpty(sFileName) Then Dim theDocument As New System.Windows.Xps.Packaging.XpsDocument(sFileName, System.IO.FileAccess.Read) DocumentViewer1.Document = theDocument.GetFixedDocumentSequence() End If Catch ex As Exception MessageBox.Show("ERROR: " &amp; ex.Message) End Try End Sub </code></pre> <p>Thanks in advance for your assistance.</p> <p><strong>Update</strong></p> <p>Here's the XAML I'm using: </p> <pre><code>&lt;ComboBox Width="Auto" IsReadOnly="True" IsEditable="True" Name="ComboBox1" Height="Auto" Margin="0" Padding="1" Grid.Column="2"&gt; &lt;ComboBoxItem&gt;123456&lt;/ComboBoxItem&gt; &lt;ComboBoxItem&gt;123457&lt;/ComboBoxItem&gt; &lt;ComboBoxItem&gt;123458&lt;/ComboBoxItem&gt; &lt;/ComboBox&gt; </code></pre>

    2. COSorry, just saw your posting. Here's the XAML I'm using - nothing fancy: <ComboBox Width="Auto" IsReadOnly="True" IsEditable="True" Name="ComboBox1" Height="Auto" Margin="0" Padding="1" Grid.Column="2"> <ComboBoxItem>123456</ComboBoxItem> <ComboBoxItem>123457</ComboBoxItem> <ComboBoxItem>123458</ComboBoxItem> </ComboBox>

    3. COOk, are the files that you want named something like c:\folder\123456.xps where the value in the combobox is the name of the file without the the .xps? Or is there something else that determines the file name?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
