The DoubleAnimation doesn't work - wpf

Question

//Create my grid and child controls
var layoutRoot = new System.Windows.Controls.Grid
{
Background = new SolidColorBrush(Colors.Blue),
Name = "layaoutRoot1",
Height = 400.0,
VerticalAlignment = System.Windows.VerticalAlignment.Stretch,
HorizontalAlignment = System.Windows.HorizontalAlignment.Stretch
};
layoutRoot.ColumnDefinitions.Add(new ColumnDefinition()
{
Width = new GridLength(1, GridUnitType.Auto)
});
layoutRoot.ColumnDefinitions.Add(new ColumnDefinition()
{
Width = new GridLength(1, GridUnitType.Star)
});
var myImage = new Image
{
Source = new BitmapImage(new Uri(#"C:\Path\to\Image\img.png")),
Stretch = Stretch.UniformToFill,
Margin = new Thickness(3),
Width = 50.0,
Height = 50.0,
};
var textBlocklbl = new TextBlock
{
Text = "Label Here",
FontFamily = new FontFamily("Arial"),
FontSize = 14.0,
FontWeight = FontWeights.Bold,
Margin = new Thickness(3)
};
layoutRoot.Children.Add(myImage);
layoutRoot.Children.Add(textBlocklbl);
System.Windows.Controls.Grid.SetColumn(myImage, 0);
System.Windows.Controls.Grid.SetColumn(textBlocklbl, 1);
grid1.Children.Add(layoutRoot); //grid1 is placed on the MainWindow
Storyboard myStorboard = new Storyboard();
DoubleAnimation myDoubleAnimation = new DoubleAnimation();
myDoubleAnimation.From = 0.0;
myDoubleAnimation.To = 300.0;
myDoubleAnimation.Duration = new Duration(TimeSpan.FromSeconds(3));
myDoubleAnimation.RepeatBehavior = RepeatBehavior.Forever;
//myDoubleAnimation.AutoReverse = true;
myStorboard.Children.Add(myDoubleAnimation);
Storyboard.SetTargetName(myDoubleAnimation, layoutRoot.Name);
Storyboard.SetTargetProperty(myDoubleAnimation, new PropertyPath(System.Windows.Controls.Grid.HeightProperty));
myStorboard.Begin();

Answer 1

Your animation cannot find source for animation. Setting TargetName will not work until you put animation into logical tree. Use StoryBoard.SetTarget(layoutRoot) instead of StoryBoard.SetTargetName(layoutRoot.Name).
Here is what you could do to resolve it:
1) First of all you could debug it. You just launch the code in Visual Studio in debug mode and keep looking into Output window until you see error there. I believe you will see it there soon - then you can fix it. There is still a chance that you won't see any errors.
2) Second, you should try to debug it again. Take your code, paste it into clean solution. Still doesn't work? Great! Keep removing parts of the code which doesn't look related to the issue. VerticalAlighnment, HorizontalAlignment, do you really need them? Can the issue be reproducible without those properties? Remove them. Less code - easier to debug. Ok, finally you have 10 lines of code but it still doesn't work. Take a sample from MSDN which is working and looks as close to your as possible and find the difference. You can even replace parts of your code with MSDN one to see whether it will help or not.
3) And ok, it still doesn't work, you haven't found any samples and there is no way for you to debug it - you need community help. Ask question correctly. If you are a professional developer then probably you've seen it many times - users coming with only one statement it doesn't work. You have to test/debug/fix it completely on your own. But those are your clients, they will pay you money eventually. This is free community which is driven only on behalf of our interest. If we are not interested to answer your question - we will never answer it. So ask a question which worth answering. Pasting the code which doesn't work is not enough. You should also provide an information regarding the part which doesn't work. And what have you tried to fix it yourself. If we will think that you're trying to exploit us - we won't answer your question.
Thanks for your time.
UPDATE Ok, just tried to debug it. Exactly as I said. Your code gives an exception that layoutRoot cannot be found. The exact message is: No applicable name scope exists to resolve the name 'layaoutRoot1'.. You just had to run your own code in VS, exactly as you said.
