Question

I’m very new to development and SO, i’m trying to build a small program to allow users to search for a employee name and return other info including a staff photo.

Building it in WPF, with C# code behind and the staff details stored in an XML file.

I can get the staff details back from the XML by searching but i need to get the image returned too so it can be displayed in the datatemplate as the results.

How is best to store the info in the XML and retrieve it along with the search results?

Thanks in advance.

     <Window.Resources>
            <DataTemplate x:Key="SearchResultsTemplate">
                <Grid Margin="4,0,4,8" Width="446" Height="68">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="Auto" />
                        <ColumnDefinition Width="*" />
                    </Grid.ColumnDefinitions>
                    <Border VerticalAlignment="Top" Margin="8" Padding="2" Background="White">
                        <Image Width="40" Height="40" Source="{Binding Path=Avatar, Mode=OneWay}" />
                    </Border>
                    <StackPanel Grid.Column="1" VerticalAlignment="Top" Margin="0,4,0,0">
                        <TextBlock x:Name="AuthorName" FontWeight="Bold" Text="{Binding Path=Author, Mode=OneWay}" />
                        <Grid Margin="0,6,0,0">
                            <Grid.RowDefinitions>
                                <RowDefinition Height="Auto" />
                                <RowDefinition Height="2" />
                                <RowDefinition Height="Auto" />
                            </Grid.RowDefinitions>
                            <TextBlock x:Name="Message" TextWrapping="Wrap" />
                        </Grid>
                    </StackPanel>
             </Grid>
            </DataTemplate>
        </Window.Resources>
        <ScrollViewer  HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Auto" BorderThickness="1">
 <ItemsControl x:Name="SearchResults" Margin="0,8,0,0" 
  Grid.Row="1" ItemTemplate="{StaticResource SearchResultsTemplate}" />
             </ScrollViewer>

Code behind:

 XDocument xdoc = XDocument.Load("data.xml");
 SearchResults.ItemsSource = from item in xdoc.Descendants("Item")
                             where (string)item.Element("Author") == searchInput
                             select new
                             {
                                Author = (string)item.Element("Author"),
                                Message = (string)item.Element("Message"),
                                Avatar = (string)item.Element("Avatar")
                            };
