Binding data to XAML while runtime

I build a Chart with a Grid and some Rectangles, like in this Post:
Drawing a chart in WPF C# design questions
Now I save this Chart to an XAML-File to fill it later by another program.
In this chart I need to bind three Values:
1. Labels
2. MaxHeight - Height (by each bar)
3. Height
My Problem is, that I don't know how to bind it correctly for using it in another application.
The other Application could give me a list or an array with the values and the label, but I dont know how I should bind unknown values to the Rectangles.
In the code below I binded the "ChartLabel" but I need all Chart Labels not only one.
When I creating the chart I don't now how much bars I will have later.
<Grid ShowGridLines="True" Background="#FFF5F5DC" Width="Auto" Margin="5,5,5,5" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Rectangle Fill="#FF0000FF" Grid.Column="{Binding Path=Test6_Val, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
<TextBox Text="{Binding Path=ChartLabel, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" BorderBrush="#00FFFFFF" Background="#00FFFFFF" HorizontalAlignment="Center" Grid.Column="5" Grid.Row="10" />
<Rectangle Fill="#FF0000FF" Grid.Column="{Binding Path=Test7_Val, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
<TextBox Text="{Binding Path=ChartLabel, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" BorderBrush="#00FFFFFF" Background="#00FFFFFF" HorizontalAlignment="Center" Grid.Column="6" Grid.Row="10" />
<Rectangle Fill="#FF0000FF" Grid.Column="{Binding Path=Test8_Val, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
<TextBox Text="{Binding Path=ChartLabel, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" BorderBrush="#00FFFFFF" Background="#00FFFFFF" HorizontalAlignment="Center" Grid.Column="7" Grid.Row="10" />
<Rectangle Fill="#FF0000FF" Grid.Column="{Binding Path=Test9_Val, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
<TextBox Text="{Binding Path=ChartLabel, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" BorderBrush="#00FFFFFF" Background="#00FFFFFF" HorizontalAlignment="Center" Grid.Column="8" Grid.Row="10" />
<Rectangle Fill="#FF0000FF" Grid.Column="{Binding Path=Test10_Val, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
<TextBox Text="{Binding Path=ChartLabel, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" BorderBrush="#00FFFFFF" Background="#00FFFFFF" HorizontalAlignment="Center" Grid.Column="9" Grid.Row="10" />
</Grid>

I'm not sure I follow your description of which part you're having a problem with.
You will have a List.
You want to use a string from that as label and a number as height.
If you iterate that you can find the max and hence calculate some sort of scaling factor so a value of half the max ends up about half the height of your chart.
The way I'd do a series like that is with an itemscontrol. Bind an observablecollection to the itemssource. An itemscontrol has a stackpanel it's contents go in. Make the orientation horizontal and define an itemtemplate. That would have a textblock for the label, (maybe rotated) and a rectangle whose height is bound to your scaled value.
Which is roughly how the terrain visualiser I wrote works.
There are no labels - so this is to give you the idea rather than cut and paste.
<ListBox ItemsSource="{Binding TerrainPointList}"
..
>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<VirtualizingStackPanel IsItemsHost="True"
Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
...
A listbox has scrollers and selecteditem. I use selecteditem in mine and that might or might not be useful to you.

UWP WrapPanel / VariableSizedGrid

i'm currently on some design issues. I need a WrapPanel which contains multiple Expander which should fit corretly as i the image shown.
So if the user opens one, some commands should appear. (can be 3 up to 10 commands.) i think a scrollview starting with 5 items should fit best)
Currently i didn't get it to work. If i toggle the first box, each box is toggled.
And if i toggle another box, it takes also the complete height.
And here the Image, if the first box is closed.
I think i need multiple Controls for this.
First is the Expander-Menu and second the VariableSizedWrapGrid. But both together doesn't work, as expected. here my current code.
<controls:DockPanel Grid.Row="1" Grid.Column="1" Background="#efefef" >
<GridView x:Name="CommandList" controls:DockPanel.Dock="Top" Margin="15" SelectionMode="None" VerticalContentAlignment="Top" >
<GridView.ItemTemplate>
<DataTemplate>
<controls:WrapPanel Name="VerticalWrapPanel" Margin="2"
VerticalSpacing="10" HorizontalSpacing="10" Orientation="Vertical">
<controls:Expander Style="{StaticResource ExpanderStyleCheckBox}" VerticalAlignment="Top" Margin="20,20,0,20" VerticalContentAlignment="Top"
IsExpanded="True" Width="500"
ExpandDirection="Down" Background="White" Tapped="Expander1_Tapped" VariableSizedWrapGrid.RowSpan="{Binding RowSpan}" >
<controls:Expander.Content>
<ListView ItemsSource="{Binding Phrases}" Margin="30,0,0,0" Background="#efefef" SelectionMode="None">
<DataTemplate>
<TextBlock TextWrapping="WrapWholeWords" VerticalAlignment="Center" />
</DataTemplate>
</ListView>
</controls:Expander.Content>
<controls:Expander.Header>
<TextBlock Margin="10" HorizontalAlignment="Left" FontSize="18" TextWrapping="WrapWholeWords" VerticalAlignment="Center">
<Run Text="{Binding Heading}" />
</TextBlock>
</controls:Expander.Header>
</controls:Expander>
</controls:WrapPanel>
</DataTemplate>
</GridView.ItemTemplate>
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<VariableSizedWrapGrid Margin="20" ItemWidth="530" VerticalAlignment="Top" VerticalChildrenAlignment="Top"
Orientation="Horizontal" MaximumRowsOrColumns="5" >
</VariableSizedWrapGrid>
</ItemsPanelTemplate>
</GridView.ItemsPanel>
</GridView>
</controls:DockPanel>
If someone could help me, this would be great.
Thanks and have a nice weekend.

Preview in designer wpf DataGrid DataGridTemplateColumn column

Is there a way to preview in the XAML designer how my DataGridTemplateColumn will looks like ?
Example:
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button Margin="2" BorderThickness="0" Background="Transparent">
<Button.Content>
<StackPanel Orientation="Horizontal">
<Image Source="/WpfImages;component/images/16x16/wheels.png"
Width="16" Height="16" ToolTip="Show wheels" />
</StackPanel>
</Button.Content>
</Button>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

Use a design-time data context bound to a design-time specific ViewModel to have data displayed in the IDE while you code your UI.
MSDN has a pretty comprehensive article on it here: (clicky!)

Listview in WinRT using C#

I want my ListView to display the items in a group horizontally as displayed in the image below. I could not find anything relating to this online. This screen was taken from the Groove music application. Since I am new to asking questions here it seems I don't have enough reputation to post images therefore I provided a link to the image in question sorry for the inconvenience.

Edit:
I am trying to imitate the groove music player for a school project this link below shows my app. Hopefully this give you a better idea of the problem.

My Xaml Code:
<ListView
x:Name="itemGridView"
Grid.Row="1"
ItemsSource="{Binding Source={StaticResource artistsItemsViewSource}}"
SelectionMode="None"
IsSwipeEnabled="false"
IsItemClickEnabled="True"
RequestedTheme="Light">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel MaxWidth="200">
<Ellipse Height="150" Width="150">
<Ellipse.Fill>
<ImageBrush Stretch="Fill" ImageSource="Assets/Artist.png"/>
</Ellipse.Fill>
</Ellipse>
<TextBlock Text="{Binding ArtistName}" FontSize="18" HorizontalAlignment="Center" Margin="0,5,0,0" TextWrapping="Wrap"/>
<TextBlock Text="{Binding AlbumCount}" FontSize="15" HorizontalAlignment="Center" Margin="0"/>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsStackPanel Width="200" HorizontalAlignment="Left" Margin="30,0,0,0"/>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.GroupStyle>
<GroupStyle>
<GroupStyle.HeaderTemplate>
<DataTemplate>
<Grid Margin="0,0,0,2">
<TextBlock Text="{Binding AlphaLetter}" FontSize="20" Foreground="{StaticResource SideButtonBlue}" />
</Grid>
</DataTemplate>
</GroupStyle.HeaderTemplate>
</GroupStyle>
</ListView.GroupStyle>
</ListView>

I think you can change the view in the listview settings to LargeIcon and then you can set Icons for each value in your listview.
But you could maybe use the ObjectListView its better than the plain ListView and you have more functions. check this out: click
I found something similar on the site of the objectlistview: here

for horizontal placement of the elements in ListView do this:
<ItemsStackPanel
Orientation="Horizontal" />
also, remove Width="200"
also you can use GridView instead of ListView

Trouble with multiple selection of a list box in wp8

I'm using ListBox to list a group of items and i want the user to select multiple items from the list. I tried it with the following code,
<ListBox x:Name="List" SelectionMode="Multiple" HorizontalAlignment="Left" Height="559" Margin="14,1,-1,0" VerticalAlignment="Top" Width="443" SelectionChanged="List_SelectionChanged_1">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical" Width="420" Height="60">
<TextBlock x:Name="tbName" Width="318" Foreground="{Binding color}" Height="35" FontSize="22" Text="{Binding Name}" Margin="-350,13,69,12" />
<Canvas x:Name="ContentPanelCanvas" Grid.Row="1" Background="Transparent" Margin="0,0,12,0">
<Line X1="0" Y1="00" X2="420" Y2="0" Stroke="Gray" StrokeThickness="0.3"/>
</Canvas>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
But still i didn't get a checkbox to select multiple items.
What is the problem?

I think it will be better if you use LongListMultiSelector from Windows Phone Toolkit
You can find code samples here. Also take a look of this question.
