Approach: Set the item source of the ListBox to a dependency property. As the property changes, the items in the ListBox will also change.

Solution:

1. Create a dependency property and its wrapper CLR property.

/// <summary>        /// The Feed dependency property.        /// </summary>      public static readonly DependencyProperty FeedProperty = DependencyProperty.Register("Feed", typeof(SyndicationFeed), typeof(FeedViewer));
/// <summary>        /// Gets or sets the feed.        /// </summary>       /// <value>The syndication feed.</value>      public SyndicationFeed Feed        {            get { return (SyndicationFeed)GetValue(FeedProperty); }            set { SetValue(FeedProperty, value); }        }

Note that FeedViewer is the user control containing the ListBox.

2. Bind the ListBox item source to the property.

There are two ways (well, at least, I think) to accomplish this.

2.1 XAML

    <UserControl x:Class="Controls.Wpf.FeedViewer"              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"              x:Name="usrFeedViewer">        <Grid>            <ListBox x:Name="uxFeedListBox"                  ItemsSource="{Binding ElementName=usrFeedViewer, Path=Feed.Items}" HorizontalContentAlignment="Stretch"                  Grid.Row="1" Margin="12,0,12,12" />        </Grid>    </UserControl>

Note that the ItemSource accepts IEnumerable. Therefore, we assign the feed items for it instead of just Feed.

2.2 Code Behind

For this approach, we are to create a PropertyChangedCallback event to handle when the Feed property is changed.

There is no need to set the ItemSource property in XAML for the ListBox.

The dependency property will be changed to:

        /// <summary>

/// The Feed dependency property.

/// </summary>

public static readonly DependencyProperty FeedProperty = DependencyProperty.Register("Feed", typeof(SyndicationFeed), typeof(FeedViewer), new FrameworkPropertyMetadata(null, new PropertyChangedCallback(OnFeedChanged)));

Now we define the event named OnFeedChanged:

        /// <summary>        /// Called when [feed changed].        /// </summary>        /// <param name="sender">The sender.</param>        /// <param name="e">The <see cref="System.Windows.DependencyPropertyChangedEventArgs"/> instance containing the event data.</param>        private static void OnFeedChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)        {            var feedViewer = (FeedViewer)sender;            var newValue = (SyndicationFeed)e.NewValue;

            feedViewer.uxFeedListBox.ItemsSource = null;            feedViewer.uxFeedListBox.ItemsSource = newValue.Items;        }

Now when you set/change the Feed property for this control in your application, the ListBox will show you corresponding feed

One solution is to surround each sub-form with <asp:Panel> element and setting its DefaultButton property to a desired button.
This way, you can have many sub-forms on one page with their own default buttons

1. Type about:config in Firefox’s address bar and press Enter key.
2. In the Filter textbox, type network.automatic-ntlm-auth.trusted-uris and press Enter key.
   You should now see the specified setting appearing in the preference name section.
3. Double click the preference name (or right click and choose Modify) to modify the value.
4. In the appearing dialog, enter the SharePoint server URLs (with no tailing “/”) separated by a comma and click OK when done.

That’s all and you are good to go

Now the question is… why does the “Build Action” property of the files under “App_Code” is “Content”?

The following xpath do the search for “asu” which returns two string – “asus striker” and “asus”:

As we can see, using lower-caes() and contains() helps search for lower-case string even though the xml contains upper-case string.
The text() function indicates the value of the node in context.
You can also try name() which indicates the name of the node.
You can try using upper-case() with upper-case input string as well.

The fix is simple, just put the closing div tag </div> on the same line as the image and the problem is fixed:

If attaching the project to w3wp.exe doesn’t seem to be an option somehow (e.g. you just cannot find it), what you need to do now is to modify some project settings as shown below.

In my case, I’ve create a host record with local.dotnetnuke as the host name.  In your case, you may want to replace http://local.dotnetnuke with http://localhost/dotnetnuke, for example.  Please note that I’ve saved my project under /DesktopModules/ContactUsForm.  So my project url becomes http://local.dotnetnuke/DesktopModules/ContactUsForm.

Save the project and try running it again.  You should now be able to debug the project
