What items can I apply transitions to?   

Hello,

I'm just starting to transition from WinForms to WPF and have a few 
questions. What items can I apply transitions to? The application I need to 
build requires many different media types transitioning in and out of the 
maid WPF screen - Video, Web Content, RSS Feed, static images, text, etc. 

I played with the basic fade transition demonstrated here: 
http://msdn2.microsoft.com/en-us/library/ms752312.aspx#otherWaysToAnimateSection 
which fades a rectangle object in and out, but I was unable to figure out how 
to apply it to web content shown in my grid. Here is what I converted the 
code to in my feeble attempt:

<Grid Name="myGrid" Loaded="myLoaded">
  <Frame Source="http://www.google.com/" />
    <Grid.Triggers>
        <EventTrigger RoutedEvent="Grid.Loaded">
           <BeginStoryboard Name="myStoryBoard">
              <Storyboard>
                 <DoubleAnimation
	   Storyboard.TargetName="myGrid"
	   Storyboard.TargetProperty="Opacity"
	   From="1.0" To="0.0" Duration="0:0:5"
	   AutoReverse="True" RepeatBehavior="Forever" />
              </Storyboard>
           </BeginStoryboard>
       </EventTrigger>
   </Grid.Triggers>   
</Grid>

Could anyone help me get a better handle on what my limitations are here? Do 
I need to load video and web content in a different type of object?

Thanks,

Glenn

You can apply transitions (and generally any kind of transforms) to 
DirectX content. Unfortunately, you cannot apply this to any content 
drawn to GDI. And as you had to find out the hard way, the Frame element 
is using Internet Explorer to display web pages, and guess what, IE 
draws against GDI... so no luck applying the transition there.

Video, images, text and other content can be transformed, so transitions 
will work.

Sorry :-(

Not that answer I was hoping for :(. But thanks so much for the response.
