WPF Wrap ListView, or Grid DataTable

i am trying to make a XAML with wrapping list view, or is it a grid, or table. I am just not sure. Please take a look at the image. How would i go about formatting my "list" that needs to wrap around the view, can someone please give me sample XAML, as i have no idea how to realize how to make this view.
It seems i need to use a ListView inside a Wrappanel of some sort? The data is dynamic, such as i can have any number of key/value pairs as seen here (open, high, lose, close, etc...) so keep in mind the pairs can have any number and they need to wrap around the control/window.
Any idea how to define such a XAML?
Thanks.

I've since figured it out. I'm using an itemcontrol instead of a list and put a wrappanel. Like this.
<ItemsControl ItemsSource="{Binding DataItems}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Width="100" Text="{Binding KeyText}"></TextBlock>
<TextBlock Width="100" Text="{Binding ValueText}"></TextBlock>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>

Custom ComboBox layout

Im trying to make a custom selector that fills the whole page and looks like this (each box represents different selection):
The elements have to be loaded from xml, allways 3 per row, infinite amount of rows possible (based on xml file).
So far i have gotten to building custom DataTemplate with this example:

But i have no idea how to approach making selection show fullscreen with multiple rows.

Since you have a fixed number of columns you can use an ItemsControl or a ListBox using a UniformGrid as the ItemPanel used to lay out the items
Sample Xaml Template
<ListBox VerticalContentAlignment="Center" HorizontalContentAlignment="Center" ItemsSource="{Binding MyElementsLoadedFromXml}">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock FontSize="26" VerticalAlignment="Center" HorizontalAlignment="Center" Text="{Binding AFieldInMyXmlElement}" />
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="3" IsItemsHost="True" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
It should look like this by default:
The IsItemsHost="True" is optional when not using a scrollviewer but as it is meant to be used in this use case I think it is better to use it here anyway
Edit: I forgot it was about ComboBox but as they behave really close to each other, if you replace ListBox by ComboBox you get what I think is your expected result :

Windows Phone 8.1 flow container for dynamic buttons

SOF Tribe,
I have a request for the identity of a flow container into which I can pour an indeterminate number of dynamically created XAML buttons. Said buttons should wrap the text as closely as possible (I think I have a template for this). But the buttons should wrap like a gridview, but run like a stackpanel. Does anyone know a container that will allow me to accomplish what the image portrays?
Currently, for the existing image below, I'm using a gridview, but the gridview sets a specific width but does flow unevenly. A stackpanel has the desired end-to-butt style but won't wrap. So, any ideas?

There is what is called the UniversalWrapPanel made by Greg Stoll. So, that's the direction I'll be taking. Now however, I've got the last little bit to tackle. How to get the bound data to respect the parent container's ability to wrap content and not just stack it up in a vertical column.
The below XAML gives me the below image result which is not quite what I want. Statically added buttons work just fine to the UniversalWrapPanel. But trying to get a binding and ItemsSource to work, well, that's beyond me at this time.
<support:UniversalWrapPanel Orientation="Horizontal" Background="White">
<ItemsControl x:Name="GridViewRecipients" ItemsSource="{Binding}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Style="{StaticResource ButtonLozengeStyle}" Content="{Binding FullName}"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</support:UniversalWrapPanel>
OK, so a bit more searching and I found this:
http://www.visuallylocated.com/post/2015/02/20/Creating-a-WrapPanel-for-your-Windows-Runtime-apps.aspx
and so here is the correct way to reference the UniversalWrapPanel within the ItemsControl:
<ItemsControl x:Name="GridViewRecipients" ItemsSource="{Binding}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<support:UniversalWrapPanel Orientation="Horizontal" Background="DodgerBlue"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Style="{StaticResource ButtonLozengeStyle}" Content="{Binding FullName}"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
For the result of:

WrapPanel in a ListView (Metro)

I have the following code in a Metro app. The listview binds up to a list of objects. My problem is that the WrapGrid assigns them equal width. But some Titles are longer then others so width should be set width to Auto. But this dont work.. anyone have any idea?
<ListView>
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" >
<TextBlock Text="{Binding Title}"/>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListView.ItemsPanel>
</ListView>

This works for me:
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid ItemWidth="250" ItemHeight="80" MaximumRowsOrColumns="7" VerticalAlignment="Center" HorizontalAlignment="Center" />
</ItemsPanelTemplate>
</ListView.ItemsPanel>
The key point here is MaximumRowsOrColumns property. Have fun :)

I think it's not the WrapGrid, but the ListView itself through the ListViewItem/ItemContainerStyle that makes them same size. I don't think there really is a workaround for that though. You could use your own ItemsControl and custom panel or calculate the desired size of each item and based on that - put the items in something like a VariableSizedWrapGrid, setting RowSpan/ColumnSpan appropriately to match that desired size. Other than that - you can either make all items wide enough to fit everything or simply clip the content and display the full strings in the detailed view once the user clicks an item.

Getting only 3 items of the text block visible on the list

I have a list box that is scrolls horizontally, it has a text block within, am binding data to the text block dynamically , this data is coming from a server,i have folders coming from the server and am displaying only the names of these folders in this list box.suppose there are 10 folders on the start of the App i want only first three names to be visible on the list(the effect should be something like the Panorama page), then when i scroll next three names should be visible and which ever is closest to the middle that folder should get expanded... and which ever name is highlighted for that name the BG of the list box should change to Green.
Please help me out am very new to WP7
the code am using is
<ListBox BorderBrush="White" Background="LightGray" ItemsSource="{Binding DisplayItem}" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Disabled" Margin="36,122,34,500" Grid.Row="2">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal">
</StackPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Height="75" Width="250" FontSize="28" Foreground="Black" Text="{Binding WidgetName}" HorizontalAlignment="Center">
</TextBlock>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

In order to achieve the panorama view, listbox is not your best choice. Code Samples has an example called Panorama/Pivot Sample.
Check it, i think this is what you're looking for, it describes the method used in addition to sample codes.
