Question

I’m developing a Windows Phone 7.1 application.

I have the following folders structure:

- Images (**folder**)
   |
   - appbar.questionmark.rest.png

- Views(**folder**)
   |
   - About.xaml

- MainPage.xaml

…

I’m trying to create an app bar programmatically with:

private void SetUpAppBar()
    {
        // Set the page's ApplicationBar to a new instance of ApplicationBar.
        ApplicationBar = new ApplicationBar();

        // Create a new button and set the text value to the localized string from AppResources.
        ApplicationBarIconButton helpButton = new ApplicationBarIconButton(new Uri("..//Images//appbar.questionmark.rest.png", UriKind.Relative));
        helpButton.Text = AppResources.Help;
        helpButton.Click += new EventHandler(helpButton_Click);
        ApplicationBar.Buttons.Add(helpButton);

        // Create a new menu item with the localized string from AppResources.
        ApplicationBarMenuItem appBarHelpMenuItem = new ApplicationBarMenuItem(AppResources.Help);
        appBarHelpMenuItem.Click += new EventHandler(helpButton_Click);
        ApplicationBar.MenuItems.Add(appBarHelpMenuItem);
    }

But I can’t see the icon on app bar. What am I doing wrong?

I have test with this:

ApplicationBarIconButton helpButton = new ApplicationBarIconButton(new Uri("..//Images//appbar.questionmark.rest.png", UriKind.Relative))

But I get an invalid path exception. I’ve also changed UriKind to Relative, Absolute and with AbsoluteOrRelative.

appbar.questionmark.rest.png is marked as Resource, and copy to directory is set to “don’t copy”.

Answer 1

The pictures Build Action should be Content.

ApplicationBarIconButton helpButton = new ApplicationBarIconButton(new Uri("/Images/appbar.questionmark.rest.png", UriKind.Relative));

Try this i hope this will work.:)

This is how MSDN describes how to add a button to the AppBar

ApplicationBarIconButton button1 = new ApplicationBarIconButton();
button1.IconUri = new Uri("/Images/YourImage.png", UriKind.Relative);
button1.Text = "button 1";
ApplicationBar.Buttons.Add(button1);

I think your problem is that your picture is set as a Resource and not as Content.
