Hi All!

Im using WPF own popup control which provides nice way to popup notifications on wanted place with ready to use animation! In my case notification is prompted top of the button (Inside of UserControl).

Only problem is that when I use my UserControl in window and resize or chage its position my prompted popup will remain its original place, it wont move with button.

How I make my popup "sticky" with target button?

Here is my Xaml

<Popup x:Name="popUpnotifyIcon" AllowsTransparency="True" PopupAnimation="Fade" Placement="Top" PlacementTarget="{Binding ElementName=myButton}" HorizontalOffset="0" VerticalOffset="20" >
    <Viewbox VerticalAlignment="Top" >
        <Image Height="50" Width="50" Source="/MyImage.png" ></Image>
    </Viewbox>
</Popup>

As it shows target will be "myButton" and showing/hiding is handled in code using popUpnotifyIcon.IsOpen property.

I tried to hook popup redrawing in usercontrols LayoutUpdated event but it leaded endless loop because popUpnotifyIcon.IsOpen state change launches also LayoutUpdated which launches that event again and again...

Hope you got idea :)

Cheers!
