How to get Narrator to read the text in a WPF Popup?

Question

I've got a WPF application which contains a button. When you press the button, a Popup opens. The Popup contains information about the meeting in question.

With Narrator turned on, the contents of the Popup are not being read. How do I get Narrator to read the Popup's contents?

Here's a sample of the Popup's contents:

                       Text="{x:Static languages:Resources.Label_MeetingID}"
                       VerticalAlignment="Top"/>
            <TextBlock Grid.Column="2"
                       Grid.Row="1"
                       AutomationProperties.AutomationId="MeetingId"
                       AutomationProperties.Name="{Binding MeetingID}"
                       AutomationProperties.LabeledBy="{Binding ElementName=MeetingIdLabel}"

                . . .
            </Grid>
        </Grid>
    </Border>
</Popup>

EDIT: The rest of the Popup consists of more TextBlocks and a couple of buttons for copying a link or all of the data into the clipboard. I didn't include it because I don't believe it matters.

Answer 1

You need to set Popup.IsKeyboardFocused to true. The default value is false.

This will move the tab focus to the popup. Just remember that you'll need to move the focus back (preferably to the trigger that opens the popup) when the user closes it.
