How can I make my animation not starting when the program starts, but to trigger it when I want with stop and start buttons? Here' s my XAML:
1 <Window2 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"3 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"4 x:Class="WpfTest.MainWindow"5 x:Name="Window"6 Title="MainWindow"7 Width="640" Height="480">8 <Window.Resources>9 <Storyboard x:Key="Storyboard1" RepeatBehavior="Forever">10 <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="BlueEllipse" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.X)">11 <SplineDoubleKeyFrame KeyTime="00:00:01" Value="406"/>12 </DoubleAnimationUsingKeyFrames>13 </Storyboard>14 </Window.Resources>15 <Window.Triggers>16 <EventTrigger RoutedEvent="FrameworkElement.Loaded">17 <BeginStoryboard Storyboard="{StaticResource Storyboard1}"/>18 </EventTrigger>19 </Window.Triggers>20 21 <Grid x:Name="LayoutRoot">22 <Button x:Name="Start" HorizontalAlignment="Left" VerticalAlignment="Top" Width="75" Content="Start" Click="StartClick"/>23 <Button x:Name="Stop" HorizontalAlignment="Left" VerticalAlignment="Top" Width="75" Content="Stop" Margin="75,0,0,0" Click="StopClick"/>24 <Ellipse x:Name="BlueEllipse" Fill="#FF132282" HorizontalAlignment="Left" Margin="75,120,0,0" VerticalAlignment="Top" Width="79" Height="79" RenderTransformOrigin="0.5,0.5">25 <Ellipse.RenderTransform>26 <TransformGroup>27 <ScaleTransform/>28 <SkewTransform/>29 <RotateTransform/>30 <TranslateTransform/>31 </TransformGroup>32 </Ellipse.RenderTransform>33 </Ellipse>34 </Grid>35 </Window>
Here' s my code:
1 using System;2 using System.Collections.Generic;3 using System.Linq;4 using System.Text;5 using System.Windows;6 using System.Windows.Controls;7 using System.Windows.Data;8 using System.Windows.Documents;9 using System.Windows.Input;10 using System.Windows.Media;11 using System.Windows.Media.Imaging;12 using System.Windows.Shapes;13 14 namespace WpfTest15 {16 /// <summary>17 /// Interaction logic for MainWindow.xaml18 /// </summary>19 public partial class MainWindow : Window20 {21 public MainWindow()22 {23 this.InitializeComponent();24 25 // Insert code required on object creation below this point.26 }27 28 private void StartClick(object sender, System.Windows.RoutedEventArgs e)29 {30 // TODO: Add event handler implementation here.31 }32 33 private void StopClick(object sender, System.Windows.RoutedEventArgs e)34 {35 // TODO: Add event handler implementation here.36 }37 }38 }
