I am making a quiz with answers are pics. I put them i a grid. I used story board to make each image change to full screen.But now I have 2 problems with it.
- How can I get width and height from grid container of answers and put them in storyboard?
-How can we make the image when we on hold,it will be full the grid container base on story board?
Cause I'm newbie with WP so maybe my code is not good. Please help me to solved these problems. Here is my code

In my xaml page:

Code:
<Grid Grid.Row="1" Name="layoutPortrait">
            <Grid.RowDefinitions>
                <RowDefinition Height="50"/>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="*"/>
            </Grid.RowDefinitions>
            <Grid Grid.Row="0" ColumnSpan="2" Margin="10">
                <ProgressBar Name="TimeBar" VerticalContentAlignment="Stretch" HorizontalAlignment="Stretch" SmallChange="0.2" Value="{Binding Timer}" Maximum="5000"/>
            </Grid>
            <TextBlock Grid.Row="1" Text="{Binding Question}" HorizontalAlignment="Stretch" VerticalAlignment="Center"/>
            
            <Grid Grid.Row="2" Margin="20">
                <Grid.RowDefinitions>
                    <RowDefinition/>
                    <RowDefinition/>
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition/>
                    <ColumnDefinition/>

In my cs file:

        {
            Image img = sender as Image;
            switch (img.Name)
            {
                case "Answer0Image":
                    Answer0Animation.Begin();
                    break;
                case "Answer1Image":
                    Answer1Animation.Begin();
                    break;
                case "Answer2Image":
                    Answer2Animation.Begin();
                    break;
                case "Answer3Image":
                    Answer3Animation.Begin();
                    break;
                case "Answer0LandScapeImage":
                    Answer0LandscapeAnimation.Begin();
                    break;
                case "Answer1LandScapeImage":
                    Answer1LandscapeAnimation.Begin();
                    break;
                case "Answer2LandScapeImage":
                    Answer2LandscapeAnimation.Begin();
                    break;
                case "Answer3LandScapeImage":
                    Answer3LandscapeAnimation.Begin();
                    break;
            }
        }
        private void OnMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
        {
            Image img = sender as Image;
            switch (img.Name)
            {
                case "Answer0Image":
                    Answer0Animation.Stop();
                    break;
                case "Answer1Image":
                    Answer1Animation.Stop();
                    break;
                case "Answer2Image":
                    Answer2Animation.Stop();
                    break;
                case "Answer3Image":

                    Answer0LandscapeAnimation.Stop();
                    break;
                case "Answer1LandScapeImage":
                    Answer1LandscapeAnimation.Stop();
                    break;
                case "Answer2LandScapeImage":

                case "Answer3LandScapeImage":
                    Answer3LandscapeAnimation.Stop();
                    break;
            }
        }

So..to be straight, you want to use a value of one of the grids in a storyboard somewhere and you want to have the image "stretch" to the full length of the grid when it's held, correct?

Yes, I do. At the moment, I'm not sure about the stretching on tap part, but I do know for the value for the Grid. In your xaml, you can give the grid a name and then use that with the ElementName attribute for the data binding, where the value for ElementName is the name of another component in your xaml.

Code:
[COLOR=blue]<[/COLOR][COLOR=#a31515]Binding[/COLOR] [COLOR=red]ElementName[/COLOR][COLOR=blue]=[/COLOR][COLOR=black]"[/COLOR][COLOR=blue]nameString[/COLOR][COLOR=black]" [COLOR=#ff0000]Path[/COLOR]=[COLOR=black]"[/COLOR][COLOR=blue]propertyValue[/COLOR][COLOR=black]"[/COLOR][/COLOR][COLOR=blue]/>[/COLOR]

Edit: I forgot about the path attribute. It's all fixed now.
