Question

I am new in windows phone ,

Now am doing a sample just trying to show an image in a stack panel.

I want to show the image in its actual height and width. But the actual height and width returns 0.

Actually the image with height of 360px and width of 480 px.

I posted my code below. Pls help.

Thanks.

MaingPage.xaml

<Grid x:Name="LayoutRoot" Background="Transparent">
    <StackPanel Name="imagePanel" ></StackPanel>
</Grid>

MainPage.xaml.cs

namespace ImageResizing
{
public partial class MainPage : PhoneApplicationPage
{
    Image myImage;
    BitmapImage bit;

    // Constructor
    public MainPage()
    {
        InitializeComponent();

        myImage = new Image();
        Uri uri = new Uri("Penguins.jpg", UriKind.Relative);
        bit = new BitmapImage(uri);
        myImage.Source = bit;

        myImage.Width = myImage.ActualWidth; // Returns 0
        myImage.Height = myImage.ActualHeight; // Returns 0

        myImage.Width = bit.PixelWidth;  // Also tried this. It returns 0 too
        myImage.Height = bit.PixelHeight; // Also tried this. It returns 0 too


        myImage.Stretch = Stretch.Fill;
        imagePanel.Children.Add(myImage);
    }
  }
}

Answer 1

They are zero until AFTER that call to myImage.Source = bit; Prior to that myImage is just an empty image that doesn’t have any content.
