    <p>I have a Page <strong>Ingredients.xaml</strong> with a GridView. This GridView displays a list of <code>Ingredient</code> objects. For each item, an image is displayed by binding to a string property of the <code>Ingredient</code> object containing the file's path (in the app's local folder). </p> <p>When I click on an item, the app navigates to <strong>Ingredient.xaml</strong>, a details page, where the image as well as all the details are displayed. There is functionality to set a new image or replace/remove the current one. </p> <p>When there is no image yet, everything works like a charm. However, as soon as a file exists already, I get the following error when trying to either delete or replace the current file: "Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))". </p> <p>At first I thought the Image in <strong>Ingredient.xaml</strong> was the issue, since it was still showing the image I was trying to delete. So i added the following line to the code: </p> <pre class="lang-cs prettyprint-override"><code>this.ingredientImage.Source = null; </code></pre> <p>The code was still throwing the exception, though. So I tried something else: I removed the Image from the GridView in <strong>Ingredients.xaml</strong>. The only place the image is shown not is in <strong>Ingredient.xaml</strong>. When I try to replace/delete the image, <code>Image.Source</code> is set to null and the file is successfully replaced/deleted. </p> <p>Apparently the Image in the GridView on the previous Page is still blocking the file, but I have no idea how I could release the file when I navigate away.</p>

    1. COHow do you display the images in Ingredients.xaml? Depending on how they are loaded - there might be different ways to close the image files.

    2. COI was setting the Source property to the URI string, that was causing the error above. I have now changed the way I use the images: I load them when I need them and copy them to a BitmapImage instead of just a string. That's working perfectly now.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
