In my silverlight app, I have two images of equal dimension.
When the user clicks on the image I would like to animate the transition of one image to the other as if it were a piece of paper being flipped with the first image on the front and the other on the back.
I haven't worked with silverlight animation, yet so I don't know where to begin.
Basically you will need two Storybards to begin with. Each Storyboard will be using PlaneProjection (in this case I am using RotationX which rotates the images around the x-axis of rotation) to do the flipping animation.
In the following example, I have created FlippingDown and FlippingUp two Storyboards. I attached a ControlStoryboardAction behavior to each of them, they will be triggered when MouseLeftButtonDown is fired.
You'll need to reference System.Windows.Interactivity and Microsoft.Expression.Interactions.

You could search for info on Projection animations in Blend. This looks like what you need: http://www.silverlightbuzz.com/2009/10/14/using-the-3d-tools-to-animate-in-blend/

I have a Storyboard at Window resources as shown below.
<Window.Resources>
<!-- Storyboard as a window resource -->
<Storyboard

The Storyboard can be started with the following string which is placed in regular Button.
<EventTrigger RoutedEvent="PreviewMouseLeftButtonDown">
<BeginStoryboard Storyboard="{DynamicResource NB}" />
</EventTrigger>
A question is How to use a data binding in order to start that Storyboard.
For example:
<DataTrigger Binding="{Binding Start_Storyboard}" Value="true">
<DataTrigger.EnterActions>
<BeginStoryboard Storyboard="{DynamicResource NB}"/>
</DataTrigger.EnterActions>
</DataTrigger>
In WPF, I'm trying to move an image from left to center, pause for a second, then move the image to the right.
I'm trying to achieve it using ObjectAnimationUsingKeyFrames.
<BeginStoryboard>
<Storyboard Storyboard.TargetName="RoundNumberText" >
<ObjectAnimationUsingKeyFrames Duration="0:0:1" Storyboard.TargetProperty="Left">
<DiscreteObjectKeyFrame Value="400" KeyTime="0:0:0.5"/>
<DiscreteObjectKeyFrame Value="1400" KeyTime="0:0:1.5"/>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</BeginStoryboard>
Somehow i got the error message on the TargetProperty that the object does not supported by this properties. I've tried with margin as well, but still giving error.
Appreciate if anyone could help.
To set the value for alignment, you need to do something like this:
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="MyImage"
Storyboard.TargetProperty="HorizontalAlignment">
<DiscreteObjectKeyFrame KeyTime="0:0:0">
<DiscreteObjectKeyFrame.Value>
<HorizontalAlignment>Center</HorizontalAlignment>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
Below is my example, where the image appears in the role of the Label:
<Grid>
<Grid.Triggers>
<EventTrigger SourceName="MoveToCenter" RoutedEvent="Button.Click">
<BeginStoryboard>
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="Test"
Storyboard.TargetProperty="HorizontalAlignment">
<DiscreteObjectKeyFrame KeyTime="0:0:0">
<DiscreteObjectKeyFrame.Value>
<HorizontalAlignment>Center</HorizontalAlignment>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames BeginTime="0:0:1"
Storyboard.TargetName="Test"
Storyboard.TargetProperty="HorizontalAlignment">
<DiscreteObjectKeyFrame KeyTime="0:0:0">
<DiscreteObjectKeyFrame.Value>
<HorizontalAlignment>Right</HorizontalAlignment>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Grid.Triggers>
<Label x:Name="Test" Content="Test" Width="300" Height="200" Background="Aqua" HorizontalAlignment="Left" />
<Button Name="MoveToCenter" Content="MoveToCenter" Width="120" Height="30" HorizontalAlignment="Right" VerticalAlignment="Bottom" />
</Grid>
I made a die for some game I'm making (in c#), it's a usercontrol which uses a storyboard to show several images after each other (like a slideshow) so it looks like a rolling 3D die. The problem is starting and stopping it at a specific keyFrame. It's seems logical to use Pause() and Resume() for this, but I can't figure out how to Pause at an exact keyFrame.
Some people use a seperate dispatcherTimer to do this, but this isn't precise enough to stop it at that exact keyframe. (for example, if you throw 4 it must stop on the 4 image).
So, it would be great if there was some method like this:
TimeSpan keyTime = new TimeSpan(0,0,0,0,750); // 750 miliseconds
myStoryBoard.ResumeTo(keyTime); // <- doesn't exist as far as I know
Here is a snippet from my storyboard in XAML:
<Storyboard x:Key="DieStoryBoard" RepeatBehavior="Forever">
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="image1">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<Visibility>Visible</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
<DiscreteObjectKeyFrame KeyTime="0:0:0.05">
<DiscreteObjectKeyFrame.Value>
<Visibility>Collapsed</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="image2">
<DiscreteObjectKeyFrame KeyTime="0:0:0.05">
<DiscreteObjectKeyFrame.Value>
<Visibility>Visible</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
<DiscreteObjectKeyFrame KeyTime="0:0:0.10">
<DiscreteObjectKeyFrame.Value>
<Visibility>Collapsed</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="image3">
<DiscreteObjectKeyFrame KeyTime="0:0:0.10">
<DiscreteObjectKeyFrame.Value>
<Visibility>Visible</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
<DiscreteObjectKeyFrame KeyTime="0:0:0.15">
<DiscreteObjectKeyFrame.Value>
<Visibility>Collapsed</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
.....
And some images to make things clearer:
try this...
my example is a rotating arrow,and I can stop it at a specified angle.
<Window.Resources>
<Storyboard x:Key="Storyboard1">
<DoubleAnimationUsingKeyFrames
Storyboard.TargetProperty="(UIElement.RenderTransform).
(TransformGroup.Children)[2].(RotateTransform.Angle)"
Storyboard.TargetName="RightPanelButton1">
<DiscreteDoubleKeyFrame KeyTime="0:0:0" Value="0.0"/>
<DiscreteDoubleKeyFrame KeyTime="0:0:1" Value="45.0"/>
<DiscreteDoubleKeyFrame KeyTime="0:0:2" Value="90.0"/>
<DiscreteDoubleKeyFrame KeyTime="0:0:3" Value="135.0"/>
<DiscreteDoubleKeyFrame KeyTime="0:0:4" Value="180.0"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</Window.Resources>
Storyboard st = ((Storyboard)this.Resources["Storyboard1"]);
st.Begin();
st.Seek(new TimeSpan(0,0,2));
st.Pause();

I have this button :
<Button x:Name="PrevAdIcon" Tag="-1" Visibility="Collapsed" Width="80" Height="80" Click="PrevAd">
<Button.Background>
<ImageBrush AlignmentY="Top" Stretch="None" ImageSource="/Images/prev.png"></ImageBrush>
</Button.Background>
</Button>
How can I change the background to /Images/prev-selected.png when a user pressed the button ? It'll give him a feedback, since it's a WP7 app
what I have so far (not working) :
<vsm:VisualState x:Name="Pressed">
<Storyboard>
<ObjectAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.0010000" Storyboard.TargetName="Background" Storyboard.TargetProperty="Background">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<ImageBrush ImageSource="/Images/prev-selected.png" Stretch="Fill"/>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</vsm:VisualState>
As far as I know, you can't change the value of the Source property on the Image element by using the VisualStateManager. However, you can just add two Image elements to the ControlTemplate: one for the Normal state and one for the Pressed state, and toggle the Visibility in the Pressed state.
<VisualState x:Name="Pressed">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="Img">
<DiscreteObjectKeyFrame KeyTime="0" Value="Collapsed" />
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="PressedImg">
<DiscreteObjectKeyFrame KeyTime="0" Value="Visible" />
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
See Peter Torr's post on "Why can't I change the Background of my Button on a Click event?" for an example and explanation of how to do this.
To add more information to Derek's answer, you should look at Gambit's answer here for full XAML that works
I want to change the source of an image using storyboard in silverlight blend on mouse over:
<VisualState x:Name="MouseOver">
<Storyboard>
---code here--
</Storyboard>
</VisualState>
Ok finally solved it :
On mouse hover i just turn out the visbility of an image to colapsed and made the visibility of other image to visible. That's it :)
<VisualState x:Name="MouseOver">
<Storyboard>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="Opacity" Storyboard.TargetName="fillColor">
<SplineDoubleKeyFrame KeyTime="0" Value=".35"/>
</DoubleAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="image">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<Visibility>Collapsed</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="hoverimage">
<DiscreteObjectKeyFrame KeyTime="0">

<Visibility>Visible</Visibility>
