WP7 Dynamic icons in ApplicationBar

Question

Dynamic icons in ApplicationBar

It's possible to have dynamic icons in ApplicationBar with dynamic images loaded from url? I tried this:

xaml:

<phone:PhoneApplicationPage.ApplicationBar>
    <shell:ApplicationBar IsVisible="True" IsMenuEnabled="True">
        <shell:ApplicationBarIconButton IconUri="" Text="Button 1"/>
        <shell:ApplicationBarIconButton IconUri="" Text="Button 2"/>
        <shell:ApplicationBar.MenuItems>
            <shell:ApplicationBarMenuItem Text="MenuItem 1"/>
            <shell:ApplicationBarMenuItem Text="MenuItem 2"/>
        </shell:ApplicationBar.MenuItems>
    </shell:ApplicationBar>

cs:

var myIcon = ApplicationBar.Buttons[1] as ApplicationBarIconButton;
myIcon.IconUri = new Uri(iconImageUrl, UriKind.Absolute);

I'm getting error: Path cannot be absolute.

Chage the second parametr to UriKind.Relative if the uri is relative - looks like this one:

"/Images/icon.png"

From a webpage? you can't. Use http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest%28v=VS.95%29.aspx – Lukasz Madon Jan 04 '11 at 12:29
Please explain more, I know how to work with dynamic Bitmaps using HttpWebRequest, but I don't know how to assign dynamic Bitmap to ApplicationBar icon. – Janci Jan 04 '11 at 16:07

I think the best idea is to save your image in isolated storage and call it with UriKind.Relative.

@Janci I suppose, you can download to Isolated Storage and use it as relative. When required, download the image in background. Even this way can serve dynamism. Are you looking for something different? – Prakash Jan 04 '12 at 19:57
