  1. POUpdating Controls from Multiple Pages on Windows Phone
    text
    copied!<p>All, I am new to Windows 7 Phone. My situation is that I have a main page which contains a <code>ScrollViewer</code> which in turn houses a <code>StackPanel</code>. I want to populate this <code>StackPanel</code> with multiple sub-<code>StackPanel</code>s (at runtime) which are to hold an Image Thumb nail a hyperlink and some basic information about the image. </p> <p>This is all good when I do this from the main page, but I want to know how to update this control (which is on the main page), but from any page other than the main page. I would like to know what is considered best practice for updating a page's control (like that outlined above) from another page.</p> <p>Obviously there are a number of ways to pass data between pages</p> <pre><code>PhoneApplicationService.Current.State["yourparam"] = param NavigationService.Navigate(new Uri("/view/Page.xaml", UriKind.Relative)); </code></pre> <p>then in other page simply</p> <pre><code>var k = PhoneApplicationService.Current.State["yourparam"]; </code></pre> <p>and many others. But <strong>what is best practice for updating a generic control from a different page?</strong></p> <p>Note: There are many question about data access and passing between pages. </p> <ol> <li><a href="https://stackoverflow.com/questions/4953491/wp7-passing-data-from-page-to-page/5980718#5980718">Passing data from page to page</a></li> <li><a href="https://stackoverflow.com/questions/3213354/how-to-pass-the-image-value-in-one-xaml-page-to-another-xaml-page-in-windows-pho">How to pass the image value in one xaml page to another xaml page in windows phone 7?</a></li> <li><a href="https://stackoverflow.com/questions/6517745/passing-image-from-one-page-to-another-windows-phone-7">Passing image from one page to another windows phone 7</a></li> </ol> <p>and more. This is not what I am asking.</p>
