  Storyboard/State Issues beta 2?

  Jun 24, 2008 09:04 AM | LINK

  I have had a look around and have not been able to figure out if this a bug or me totally missing something.

   Create a storyboard in xaml and then trying to refrence it in the code behind file. 

   So there are 2 ways i would expect to be able to refrence this storyboard 1 being Show.Storyboard.*, the other being storyboard1.* , and then be able to modify them. So event handlers cannot be created either which is a bit annoying.

  Both these cause a null pointer on either Show or storyboard1

  Either way i am trying to either set the Value of the property to be an integer in the codebehind declared as private int newWidth = 150; so if anyone could show a different way to do that it would be great i had a brief attempt at binding but with no results.

  Thanks in advance
  J

  Xaml below

  <vsm:VisualState x:Name="Show">

  <Storyboard x:Name="storyboard1">

  <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.0010000" Storyboard.TargetName="mVideoPlayer" Storyboard.TargetProperty="(FrameworkElement.Width)">

  <SplineDoubleKeyFrame KeyTime="00:00:00" Value="320"/>

  </DoubleAnimationUsingKeyFrames>

  </Storyboard>

  </vsm:VisualState>

  Hi,

  What kind of error are you having?

  Are you writting this code by hand or are you using Blend? You should use Blend unless you really dominate the XAML.

  Where is this code? Inside a style?

  Can you post more code?

  Thx,

  Nuno

  Nullrefrence exception being thrown, pretty sure it used to work doing it this way, for storyboards etc

  Xaml:

  </Grid>

  cs:

  using System.Windows;

  using System.Windows.Controls;

  namespace SilverlightApplication4

  {

  public partial class Page : UserControl

  {

  public Page()

  {

  // Required to initialize variables

  InitializeComponent();

  }

  private void RedButton_Click(object sender, RoutedEventArgs e)

  {

  Red.Storyboard.Begin();

  }

  private void BlueButton_Click(object sender, RoutedEventArgs e)

  {

  BlueStory.Begin();

  }

  }

  }

   

  I am looking to edit the storyboard targets once they have been created / run indivdually

  you dont need VSM here. you could just move the Storyboards in to the UserControl Resources section and when the button is clicked you can do

  (this.Resources["sb1"] as Storyboard).Begin(); //sb1 is the key given for the storyboard
