strange behaviour frame in window

Question

the XAML+c# sample below, behave strange (and unwished) effect: when clicked on polygon and handler execute, main window "disappear", but application keep focus (as seen on taskbar) . Next click on app element on taskbar make focus lost by application, and next more click restore focus and window with its all content.

Anyone has some suggestion to override this behaviour (problem) ?

XAML:

<Window x:Class="UntitledProject1.Window1"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="Root Window"

WindowStyle="None" WindowState="Maximized" Topmost="True"

>

<Canvas x:Name="scatola">

<Canvas.Triggers>

<EventTrigger RoutedEvent="Ellipse.KeyUp">

<BeginStoryboard>

<Storyboard x:Name="anim_attivazione">

<DoubleAnimation

Storyboard.TargetName="contenuto"

Storyboard.TargetProperty="Width"

From="0" To="1024" Duration="0:0:5" AutoReverse="False" />

<DoubleAnimation

Storyboard.TargetName="contenuto"

Storyboard.TargetProperty="Height"

From="0" To="768" Duration="0:0:5" AutoReverse="False" />

</Storyboard>

</BeginStoryboard>

</EventTrigger>

</Canvas.Triggers>

<Polygon Canvas.Left="100" Canvas.Top="100" Points="40,80 40,64 80,64 80,16 40,16 40,0 0,40" Fill="Blue" Stroke="Black" StrokeThickness="2" MouseDown="attiva_sx"/>

<Frame x:Name="contenuto" Source="http://localhost" Canvas.Top="100" Canvas.Left="200" Width="0" Height="0" NavigationUIVisibility="Hidden" Content="Frame" Opacity="1"/>

</Canvas>

</Window>

Answer 1

any suggestions about this ?

It should be enough for me (at this moment) only to know if it is a bug or it is due to my mistake (maybe combining such types of classes ?)

Answer 2

Alberto,

Are you still seeing this issue? I tried your code, and I am not seeing the issue you reported.

Thanks,
Lauren

Answer 3

Yes Lauren,

problem for me is still open (same effect on two different PC); but I still use June CTP SDK/run-time due to lack of Orcas add-in in July CTP.

If last runtime solve the problem is enough for me, I can wait for next complete build.

thank you

Alberto

Answer 4

Lauren,

now I'm using RC1 release. So I checked it again and I can confirm the problem is gone away.

Thank you very much.
