wpf help binding data to controls in TabControl

So I have a TabControl with two TabItems, each TabItem has the same controls on it (8 TextBlocks) and will display data under the same bindings as their counterparts on the other TabItem.
The xaml and cs code that I have is below, but when I try execute it I get this error.
Items collection must be empty before using ItemsSource.
XAML for TabItem Structure
<TabControl Name="tbcIndividualStats" HorizontalAlignment="Left" Height="652" VerticalAlignment="Top" Width="1338" ItemsSouce="{Binding tabcontrolitems}">
<!--Template for all tabs (idea is to have them dynamically created eventually)-->
<!--Content template-->
<TabControl.ContentTemplate>
<DataTemplate>
<Grid>
<!--Border just holds the stuff-->
<Border BorderBrush="#FF53535B" BorderThickness="3" HorizontalAlignment="Left" Height="452" VerticalAlignment="Top" Width="520" Margin="10,135,0,0">
<StackPanel Margin="0,0,-1,0">
<TextBlock Name="txtVenue" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding Venue}" />
<TextBlock Name="txtTopSpeed" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding TopSpeed}" />
<TextBlock Name="txtDistRun" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding DistRun}" />
<TextBlock Name="txtTimeLow" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding TimeLow}" />
<TextBlock Name="txtTimeMed" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding TimeMed}" />
<TextBlock Name="txtTimeHigh" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding TimeHigh}" />
<TextBlock Name="txtTimeSprint" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding TimeSprint}" />
<TextBlock Name="txtSprintDist" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding SprintDist}" />
</StackPanel>
</Border>
</Grid>
</DataTemplate>
</TabControl.ContentTemplate>
<!--Item Template-->
<TabControl.ItemTemplate>

<!--Border just holds the stuff-->
<Border BorderBrush="#FF53535B" BorderThickness="3" HorizontalAlignment="Left" Height="452" VerticalAlignment="Top" Width="520" Margin="10,135,0,0">
<StackPanel Margin="0,0,-1,0">
<TextBlock Name="txtVenue" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding Venue}" />
<TextBlock Name="txtTopSpeed" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding TopSpeed}" />

</StackPanel>
</Border>
</Grid>
</DataTemplate>
</TabControl.ItemTemplate>
<TabItem Header="PlayerName" Background="Transparent" />
<TabItem Header="PlayerName2" Background="Transparent" />
</TabControl>
C# for Binding Data
public class TabItemContent
{
public string Venue { get; set; }
public string TopSpeed { get; set; }
public string DistRun { get; set; }
public string TimeLow { get; set; }
public string TimeMed { get; set; }
public string TimeHigh { get; set; }
public string TimeSprint { get; set; }
public string DistSprint { get; set; }
}
public void foo()
{
//All one line of code
//FileLoadData is a List of another class where all my data is stored
var tabitemcontents = new List<TabItemContent> { new TabItemContent { Venue = FileLoadData[0].Venue, TopSpeed = FileLoadData[0].TopSpeed.ToString(), DistRun = FileLoadData[0].TotalDistance.ToString(), TimeLow = FileLoadData[0].TimeLow.ToString(),
TimeMed = FileLoadData[0].TimeMed.ToString(), TimeHigh = FileLoadData[0].TimeHigh.ToString(), TimeSprint = FileLoadData[0].TimeSprint.ToString(), DistSprint = "null"},
new TabItemContent { Venue = FileLoadData[1].Venue, TopSpeed = FileLoadData[1].TopSpeed.ToString(), DistRun = FileLoadData[1].TotalDistance.ToString(), TimeLow = FileLoadData[1].TimeLow.ToString(),
TimeMed = FileLoadData[1].TimeMed.ToString(), TimeHigh = FileLoadData[1].TimeHigh.ToString(), TimeSprint = FileLoadData[1].TimeSprint.ToString(), DistSprint = "null"}};
//Error here, supposed to add to the TabItems
tbcIndividualStats.ItemsSource = tabitemcontents;
}
I've been looking for a solution for ages and I can't get one to work. I just need to bind that data from FileLoadData[0] and FileLoadData[1] to the two TabItems respectivly.

I would adopt a different strategy:
Add to your model, the name that you want to show in the Header of the Tabitem:
public class TabItemContent
{
public string PlayerName {get; set;} // New Property for the Tabitem Header
public string Venue { get; set; }
public string TopSpeed { get; set; }
public string DistRun { get; set; }
public string TimeLow { get; set; }
public string TimeMed { get; set; }
public string TimeHigh { get; set; }
public string TimeSprint { get; set; }
public string DistSprint { get; set; }
}
Then i'd change the Xaml considering this new attribute:
<TabControl Name="tbcIndividualStats" HorizontalAlignment="Left" Height="652" VerticalAlignment="Top" Width="1338">
<!--Template for all tabs (idea is to have them dynamically created eventually)-->
<!--Content template-->
<TabControl.ContentTemplate>
<DataTemplate>
<Grid>
<!--Border just holds the stuff-->
<Border BorderBrush="#FF53535B" BorderThickness="3" HorizontalAlignment="Left" Height="452" VerticalAlignment="Top" Width="520" Margin="10,135,0,0">
<StackPanel Margin="0,0,-1,0">
<TextBlock Name="txtVenue" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding Venue}" />
<TextBlock Name="txtTopSpeed" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding TopSpeed}" />
<TextBlock Name="txtDistRun" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding DistRun}" />
<TextBlock Name="txtTimeLow" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding TimeLow}" />
<TextBlock Name="txtTimeMed" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding TimeMed}" />
<TextBlock Name="txtTimeHigh" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding TimeHigh}" />
<TextBlock Name="txtTimeSprint" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding TimeSprint}" />
<TextBlock Name="txtSprintDist" Margin="10,7" FontSize="30" Foreground="White" Text="{Binding SprintDist}" />
</StackPanel>
</Border>
</Grid>
</DataTemplate>
</TabControl.ContentTemplate>
<!--Item Template-->
<TabControl.ItemTemplate>
<DataTemplate>
<Border>
<Textblock = Text="{Binding PlayerName}"/>
</Border>
</DataTemplate>
</TabControl.ItemTemplate>
</TabControl>
EDIT: the item template is the template for the tabitem button and content template is for its content. Some references here: TabItem.ItemTemplate vs TabItem.ContentTemplate
I've also removed the two TabItem defined inside TabControl.
Remember also to set the ItemsSource -> if you set it in code-behind, remove this line: ItemsSouce="{Binding tabcontrolitems}".

Remove these <TabItem> elements from the XAML:
<TabItem Header="PlayerName" Background="Transparent" />
<TabItem Header="PlayerName2" Background="Transparent" />
You can't both add individual items to the TabControl and use an ItemsSource. It's one way or the other.

filter xaml gridview with combo box

I am just starting off with windows 8 apps development and I want to be able to filter a gridview using the selected value in a combobox
my xaml page code behind
public sealed partial class MainPage : Page
{
public ObservableCollection<Recording> MyMusic = new ObservableCollection<Recording>();
public MainPage()
{
this.InitializeComponent();
// Add items to the collection.
MyMusic.Add(new Recording("Chris Sells", "Chris Sells Live",
new DateTime(2008, 2, 5)));
MyMusic.Add(new Recording("Luka Abrus",
"The Road to Redmond", new DateTime(2007, 4, 3)));
MyMusic.Add(new Recording("Jim Hance",
"The Best of Jim Hance", new DateTime(2007, 2, 6)));
// Set the data context for the combo box.
//ComboBox1.DataContext = MyMusic;
this.DataContext = new CollectionViewSource { Source = MyMusic };
}
}
Class
public class Recording
{
public Recording() { }
public Recording(string artistName, string cdName, DateTime release)
{
Artist = artistName;
Name = cdName;
ReleaseDate = release;
}
public string Artist { get; set; }
public string Name { get; set; }
public DateTime ReleaseDate { get; set; }
// Override the ToString method.
public override string ToString()
{
return Name + " by " + Artist + ", Released: " + ReleaseDate.ToString("d");
}
}
Xaml mark up
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<ComboBox x:Name="ComboBox1" HorizontalAlignment="Left" Margin="542,108,0,0" VerticalAlignment="Top" Width="360" ItemsSource="{Binding}">
<ComboBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="2">
<TextBlock Text="Artist:" Margin="2" />
<TextBlock Text="{Binding Artist}" Margin="2" />
<TextBlock Text="CD:" Margin="10,2,0,2" />
<TextBlock Text="{Binding Name}" Margin="2" />
</StackPanel>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
<!--<StackPanel x:Name="RecordingDetails" Margin="542,150,10,30">
<TextBlock Text="{Binding Artist}" FontWeight="Bold" FontSize="30" />
<TextBlock Text="{Binding Name}" FontStyle="Italic" FontSize="30" />
<TextBlock Text="{Binding ReleaseDate}" FontSize="30" />
</StackPanel>-->
<GridView
x:Name="itemGridView"
AutomationProperties.AutomationId="ItemGridView"
AutomationProperties.Name="Grouped Items"
Grid.RowSpan="2"
Padding="116,137,40,46"
ItemsSource="{Binding}"
SelectionMode="None"
IsSwipeEnabled="false" >
<GridView.ItemTemplate>
<DataTemplate>
<Grid HorizontalAlignment="Left" Width="250" Height="250">
<StackPanel VerticalAlignment="Bottom" Background="{ThemeResource ListViewItemOverlayBackgroundThemeBrush}" Name="test">
<TextBlock Text="{Binding Artist}" Foreground="{ThemeResource ListViewItemOverlayForegroundThemeBrush}" Style="{StaticResource TitleTextBlockStyle}" Height="60" Margin="15,0,15,0"/>
<TextBlock Text="{Binding Name}" Foreground="{ThemeResource ListViewItemOverlaySecondaryForegroundThemeBrush}" Style="{StaticResource CaptionTextBlockStyle}" TextWrapping="NoWrap" Margin="15,0,15,10"/>
<TextBlock Text="{Binding ReleaseDate}" Foreground="{ThemeResource ListViewItemOverlaySecondaryForegroundThemeBrush}" Style="{StaticResource CaptionTextBlockStyle}" TextWrapping="NoWrap" Margin="15,0,15,10"/>
</StackPanel>
</Grid>
</DataTemplate>
</GridView.ItemTemplate>
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsWrapGrid GroupPadding="0,0,70,0"/>
</ItemsPanelTemplate>
</GridView.ItemsPanel>
so essentially I just need to filter the gridview dynamically using combo box value selected.
Kindly appreciate help and guidaince please.

}
// No need to implement converting back on a one-way binding
public object ConvertBack(object value, Type targetType,

{
throw new NotImplementedException();
}
}
And this produces the following output

C# ListBox, different background for each item

I have ListBox in xaml:
<ListBox Name="feedListBox" Height="758" HorizontalAlignment="Center" Margin="0,10,0,0" VerticalAlignment="Top" Width="480" ScrollViewer.VerticalScrollBarVisibility="Auto" SelectionChanged="feedListBox_SelectionChanged" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="1" Background="White">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel VerticalAlignment="Top" Width="480">
<TextBlock FontWeight="Bold" FontSize="24" Name="feedTitle" TextWrapping="Wrap" Margin="12,0,0,0" HorizontalAlignment="Left" Foreground="#FF000000" Text="{Binding Title.Text, Converter={StaticResource RssTextTrimmer}}" />
<TextBlock Name="feedSummary" Foreground="#FF000000" TextWrapping="Wrap" Margin="12,0,0,0" Text="{Binding Summary.Text, Converter={StaticResource RssTextTrimmer}}" />

<Border BorderThickness="1" Height="2" HorizontalAlignment="Center" VerticalAlignment="Top" Width="480" BorderBrush="Black" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
How can I specify different background for each item?

add a Brush property to your viewmodel and bind the controls in your DataTemplate to it
ViewModel:
using System.ComponentModel;
using System.Windows.Media;
...
public class YourViewModel : INotifyPropertyChanged{
...
private Brush _backgroundCol = Brushes.Red; //Default color
public Brush BackgroundCol
{
get { return _backgroundCol; }
set
{
_backgroundCol = value;
OnPropertyChanged("BackgroundCol");
}
}
...
}
xaml:
<TextBlock Name="feedPubDate" Background="{Binding Path=BackgroundCol}" />
for Information about how to implement the INotifyPropertyChanged interface have a look at: Implementing INotifyPropertyChanged - does a better way exist?

Try this:
XAML:
<ListBox Name="feedListBox" Height="758" HorizontalAlignment="Center" Margin="0,10,0,0" VerticalAlignment="Top" Width="480" ScrollViewer.VerticalScrollBarVisibility="Auto" SelectionChanged="feedListBox_SelectionChanged" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="1" Background="White">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel VerticalAlignment="Top" Width="480">
<Grid Background="{Binding feedTitleBack}">
<TextBlock FontWeight="Bold" FontSize="24" Name="feedTitle" TextWrapping="Wrap" Margin="12,0,0,0" HorizontalAlignment="Left" Foreground="#FF000000" Text="{Binding Title}"/>
</Grid>
<Grid Background="{Binding feedSummaryBack}">
<TextBlock Name="feedSummary" Foreground="#FF000000" TextWrapping="Wrap" Margin="12,0,0,0" Text="{Binding Summary}" />
</Grid>
<Grid Background="{Binding feedPubDateBack}">
<TextBlock Name="feedPubDate" Foreground="#FF939393" Margin="12,0,10,10" Text="{Binding PublishDate}" HorizontalAlignment="Right" />
</Grid>
<Border BorderThickness="1" Height="2" HorizontalAlignment="Center" VerticalAlignment="Top" Width="480" BorderBrush="Black" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
CS:
public class data
{
public string Title { get; set; }
public string feedTitleBack { get; set; }
public string Summary { get; set; }
public string feedSummaryBack { get; set; }
public string PublishDate { get; set; }
public string feedPubDateBack { get; set; }
public data() { }
public data(string Title, string feedTitleBack, string Summary, string feedSummaryBack, string PublishDate, string feedPubDateBack)
{
this.Title = Title;
this.feedTitleBack = feedTitleBack;
this.Summary = Summary;
this.feedSummaryBack = feedSummaryBack;
this.PublishDate = PublishDate;
this.feedPubDateBack = feedPubDateBack;
}
}
void loadData()
{
List<data> obj = new List<data>();
obj.Add(new data("Title1", "Red", "Summary1", "Green", "Date", "Blue"));
obj.Add(new data("Title1", "#DD4B39", "Summary1", "#006621", "Date", "#1A0DAB"));
feedListBox.ItemsSource = obj;
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
base.OnNavigatedTo(e);
loadData();
}

How to set tooltip with many rows for each (dynamic) listbox item in Silverlight

I would like to set in Silverlight for each item in a ListBox a tooltip with many rows.
In XAML i have a listbox and a button:
<ListBox Height="100" HorizontalAlignment="Left" Margin="24,136,0,0" Name="listBox1" VerticalAlignment="Top" Width="109" ItemsSource="{Binding}">
<Button Content="Add" Name="button_add" VerticalAlignment="Top" Width="118" Click="add_Click">
in c#
private void button_add_Click(object sender, RoutedEventArgs e)
{
ObservableCollection<Person> obs1 = new ObservableCollection<Person>();
obs1.Add(new Person(){Name="Name1", Age=1});
obs1.Add(new Person(){Name="Name2", Age=2});
listBox1.ItemsSource = obs1;
// This Line of Code MUST NOT BE USED!! listBox1.DisplayMemberPath = "Name";
}
public class Person
{
public String Name { get; set; }
public int Age { get; set; }
public override string ToString()
{
return Name;
}
}
I would like to show for each item the Age as my tooltip.
Edit: Ok, this is the Solution for showing only AGE as tooltip. That is one Line/Row.
<ListBox Height="100" HorizontalAlignment="Left" Margin="24,136,0,0" Name="listBox1" VerticalAlignment="Top" Width="109" ItemsSource="{Binding}">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}" ToolTipService.ToolTip="{Binding Age}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
But what if i want to show a Tooltip with 2 Lines? something like:
Name: Name1
Age: 1
Edit: 3 rows, 2 columns. i also added public String Comment { set; get; } to class Person
<ListBox Height="100" HorizontalAlignment="Left" Margin="24,136,0,0" Name="listBox1" VerticalAlignment="Top" Width="109" ItemsSource="{Binding}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<ToolTipService.ToolTip>
<ToolTip>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="20"></RowDefinition>
<RowDefinition Height="20"></RowDefinition>
<RowDefinition Height="40"></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="80"/>
<ColumnDefinition Width="250"/>
</Grid.ColumnDefinitions>
<TextBlock Text="Name: " Grid.Row="0" Grid.Column="0" />
<TextBlock Text="{Binding Name}" Grid.Row="0" Grid.Column="1"/>
<TextBlock Text="Age: " Grid.Row="1" Grid.Column="0"/>
<TextBlock Text="{Binding Age}" Grid.Row="1" Grid.Column="1"/>
<TextBlock Text="Comment: " Grid.Row="2" Grid.Column="0"/>
<TextBlock Text="{Binding Comment}" Grid.Row="2" Grid.Column="1" TextWrapping="Wrap" />
</Grid>
</ToolTip>
</ToolTipService.ToolTip>
<TextBlock Text="{Binding Name}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
But there is stil a problem. The comment can be short or long, so i would like to make the ROWS/LINES/SPACE for Comment to be variable or else Text is cut off.

You can use any controls for tooltip content:
<ToolTipService.ToolTip>
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Name}" />
<TextBlock Text="{Binding Age}" />
</StackPanel>
</ToolTipService.ToolTip>
Other possibility would be to use a converter, that returns the Name and Age separated by \r\n.
