Hi everyone !
I whant to apply a little storyboard to a collection of labels in my window.
My storyboard is like that :
<Storyboard x:Key="Storyboard1" AutoReverse="True" RepeatBehavior="Forever">
<ColorAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="label" Storyboard.TargetProperty="(Label.Foreground).(SolidColorBrush.Color)">
<SplineColorKeyFrame KeyTime="00:00:00.1000000" Value="#FFFFFF"/>
</ColorAnimationUsingKeyFrames>
</Storyboard>
I have a window composed of that :
<Grid Background="#FF000000">
<Viewbox HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="Uniform">
<UniformGrid x:Name="grid" Background="#FF000000" />
</Viewbox>
</Grid>
When I want to start my storyboard I do that :
Storyboard.SetTarget( _stb, myLabel );
_stb.Begin();
where _std is my storyboard loaded by the window's resources.
The animation works fine, but on all labels (not only the one I want).
I tried to switch SetTarget by SetTargetName but labels are created into my window by the constructor and names can not be founded when I try "SetTargetName".
Do you have any ideas ?
Thanks :)
------------ Edit : We asked me to be more descriptive --------------------------------------------------------------------
Label are not created directly in the xaml, they are created by the constructor of the window :
public SpellerWindow(IKeyboard keyboard, int colomnNumber, SolidColorBrush background, SolidColorBrush foreground )
{
InitializeComponent();
grid.Columns = colomnNumber;
int i = 0;
foreach( IKey key in keyboard.Zones.Default.Keys )
{
Label lb = new Label();
lb.Foreground = foreground;
lb.Name = "label"+(i++).ToString();
lb.Content = key.ActualKeys[keyboard.CurrentMode].UpLabel;
lb.HorizontalAlignment = HorizontalAlignment.Center;
lb.VerticalAlignment = VerticalAlignment.Center;
Viewbox box = new Viewbox();
box.Stretch = Stretch.Fill;
box.Child = lb;
box.Tag = key;
grid.Children.Add( box );
}
}
Animations are started by an event handler :
void Highlighter_StartAnimation( object sender, HiEventArgs e )
{
Storyboard stb;
if( !_anims.TryGetValue( e.Step.Animation.Name, out stb ) )
{
stb = (Storyboard)_window.FindResource( e.Step.Animation.Name );
_anims.Add( e.Step.Animation.Name, stb );
}
DoAnimations( _zones[e.Step.Zone], stb );
}
Finally, animations are started by DoAnimations :
void DoAnimations( List<Label> labels, Storyboard stb )
{
foreach( Label lb in labels )
{
Storyboard.SetTarget( stb, lb );
stb.Begin();
}
}
I want to highlight a collection of labels, but all labels are flashing.
I don't know why, but I try to create a label into the Xaml directly, and set a Storyboard.TargetName (bound to the name of the label) in the Xaml of the storyboard. And it's working ...
Now you know everything.
Thanks for you help :)
