      &lt;ItemsControl.ItemTemplate&gt;
          &lt;DataTemplate&gt;
              &lt;StackPanel&gt;
                  &lt;HyperlinkButton Content="{Binding Time}"&gt;

                      &lt;/ToolTipService.ToolTip&gt;
                      &lt;i:Interaction.Triggers&gt;
                          &lt;i:EventTrigger EventName="Click"&gt;
                              &lt;i:InvokeCommandAction 
                                  Command="{Binding HyperLinkButtonCommand}" 
                                  CommandParameter="{Binding 
                                      ElementName=transcriptionTextControl }" /&gt;
                          &lt;/i:EventTrigger&gt;
                      &lt;/i:Interaction.Triggers&gt;
                  &lt;/HyperlinkButton&gt;
                  &lt;sdk:Label Content="{Binding Description}"/&gt;
              &lt;/StackPanel&gt;
          &lt;/DataTemplate&gt;
      &lt;/ItemsControl.ItemTemplate&gt;
  &lt;/ItemsControl&gt;
