I actually do not know the design of your "ChatbubbleControl" usercontrol but I found one issue why values are not getting bound.

<phone:PhoneApplicationPage.Resources>

<ItemsPanelTemplate x:Key="imgItemPanel">
    <StackPanel Orientation="Vertical" />
</ItemsPanelTemplate>
<DataTemplate x:Key="imgItemTemplate" >

    <chatbubble:ChatBubbleControl x:Name="ChatBubble" xyz="{Binding}" Hold="ChatBubbleControl_Hold_1"  />

</DataTemplate>

</phone:PhoneApplicationPage.Resources>

You are binding value to ItemsControl but you are not binding any value to actual control (here, chatbubblecontrol) that is displaying the value on screen. The solution is the you need to create a property to your usercontrol e.g.: Here, I made a test property named "xyz". and then try to bind the values to it.

Hope this will help you conceptually.
