One SelectedItem For Multiple Wpf Controls

I have a list box Bound to XML data correctly , but i have multiple Tree Views inside this listbox which you can select item for every one of them!
i want single item selecting from all of these tree views. which every one of those are inside an unique expander.
if you look at my xml data ,consider i have 2 groups inside xml , i can select item for both of those groups in listbox which now they are different treeviews in my ui , and i want single item selecting for all this listbox items.
<ListBox Background="Transparent" BorderThickness="0" SelectedValue="{Binding SelectedMenuValue,Mode=TwoWay}" ItemsSource="{Binding Path=Items,Source={StaticResource XmlSourceMenu}}">
<ListBox.Resources>
<DataTemplate DataType="{x:Type revoxml:Group}">
<Expander Header="{Binding Title}">
<TreeView ItemsSource="{Binding Menus}">
<TreeView.ItemTemplate>
<HierarchicalDataTemplate ItemsSource="{Binding}">
<StackPanel Orientation="Horizontal" Margin="10 0">
<fa:ImageAwesome Height="30" Width="30" VerticalAlignment="Center" Margin="5" Icon="{Binding Icon}" />
<TextBlock Text="{Binding Title}" Height="30" VerticalAlignment="Center" Margin="5"/>
</StackPanel>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
</TreeView>
</Expander>
</DataTemplate>
<DataTemplate DataType="{x:Type revoxml:SubMenu}">
<StackPanel Orientation="Horizontal" Margin="10 0">
<fa:ImageAwesome Height="30" Width="30" VerticalAlignment="Center" Margin="5" Icon="{Binding Icon}" />
<TextBlock Text="{Binding Title}" Height="30" VerticalAlignment="Center" Margin="5"/>
</StackPanel>
</DataTemplate>
</ListBox.Resources>
</ListBox>
for easier understanding data for this listbox comming from xml file like this :
<MainMenu>
<Group Title="title">
<SubMenu Icon="Inbox" Title="inbox" Tag="38"/>
<SubMenu Icon="CommentingOutline" Title="New Message" Tag="37"/>
<SubMenu Icon="Tachometer" Title="Archive" Tag="39"/>
<Menu Icon="CartArrowDown" Title="purchases" >
<SubMenu Icon="CartArrowDown" Title="new" Tag="26"/>
<SubMenu Icon="CartPlus" Title="list" Tag="28"/>
</Menu>
</Group>
<SubMenu Icon="InfoCircle" Title="info" Tag="6000" />
<SubMenu Icon="Close" Title="close" Tag="0"/>
</MainMenu>

this should solve it ! but you need to implement your own selected item, or you could change groupboxes to expander and items control to tree view to match your code
<Style TargetType="StackPanel" x:Key="HoverStackPanelStyle">
<Setter Property="Background" Value="Transparent"></Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" Value="Red"/>
</Trigger>
</Style.Triggers>
</Style>
<ScrollViewer>
<HeaderedItemsControl Background="Transparent" ItemsSource="{Binding Path=Items,Source={StaticResource XmlSourceMenu}}">
<ItemsControl.Resources>
<DataTemplate DataType="{x:Type revoxml:SubMenu}">
<StackPanel Orientation="Horizontal" Margin="10 0" Style="{StaticResource HoverStackPanelStyle}">
<fa:ImageAwesome Height="30" Width="30" VerticalAlignment="Center" Margin="5" Icon="{Binding Icon}" />
<TextBlock Text="{Binding Title}" FontFamily="{StaticResource nazanin}" Height="30" VerticalAlignment="Center" Margin="5"/>
</StackPanel>
</DataTemplate>
<HierarchicalDataTemplate DataType="{x:Type revoxml:Menu}" ItemsSource="{Binding Menus}">
<GroupBox Header="{Binding Title}" Margin="0 5">
<ItemsControl ItemsSource="{Binding Menus}">
<ItemsControl.Resources>
<DataTemplate DataType="{x:Type revoxml:SubMenu}">
<StackPanel Name="StackPanel" Orientation="Horizontal" Margin="10 0" Style="{StaticResource HoverStackPanelStyle}">
<fa:ImageAwesome Height="30" Width="30" VerticalAlignment="Center" Margin="5" Icon="{Binding Icon}" />
<TextBlock Text="{Binding Title}" FontFamily="{StaticResource nazanin}" Height="30" VerticalAlignment="Center" Margin="5"/>
</StackPanel>
</DataTemplate>
</ItemsControl.Resources>
</ItemsControl>
</GroupBox>
</HierarchicalDataTemplate>
</ItemsControl.Resources>
</HeaderedItemsControl>
</ScrollViewer>

how to show complete data in listbox using c# for windows phone

I am developing an app where i need to show data from web service in a listbox. I am able to show data in my listbox but its not showing the complete data. There is some problem on managing the width of my box which i am not able to fix. Can anyone please help. Here is the code:
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<ScrollViewer Margin="0,17,0,49" VerticalScrollBarVisibility ="Visible" AllowDrop="False" ManipulationMode="Control">
<ListBox Name="listBox1" Margin="68,106,58,662">
<ListBox.ItemTemplate>
<DataTemplate>
<Button Width="300" Height="120">
<Button.Content>
<StackPanel Orientation="Horizontal" Height="80" Width="80" Margin="0,0,0,0">
<StackPanel Orientation="Vertical" Height="80">
<TextBlock Text="{Binding Path=News_Title}" TextWrapping="Wrap" ></TextBlock>
<TextBlock Text="{Binding Path=News_Description}" TextWrapping="Wrap"></TextBlock>
<TextBlock Text="{Binding Path=Date_Start}" TextWrapping="Wrap"></TextBlock>
</StackPanel>
</StackPanel>
</Button.Content>
</Button>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</ScrollViewer>
</Grid>

Everything is fine here, just few things were making the code messy, I have fixed them.
See the updated grid now :)
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<ListBox Name="listBox1">
<ListBox.ItemTemplate>
<DataTemplate>
<Button>
<Button.Content>
<ScrollViewer HorizontalScrollBarVisibility="Auto" Height="80" Width="400">
<StackPanel Orientation="Horizontal" Margin="0,0,0,0">
<StackPanel Orientation="Vertical" Height="80">
<TextBlock Text="{Binding Path=News_Title}" TextWrapping="Wrap" ></TextBlock>
<TextBlock Text="{Binding Path=News_Description}" TextWrapping="Wrap"></TextBlock>
<TextBlock Text="{Binding Path=Date_Start}" TextWrapping="Wrap"></TextBlock>
</StackPanel>
</StackPanel>
</ScrollViewer>
</Button.Content>
</Button>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
Check this, it would help :)

Multi-column stackpanel or alternative

I have the following XAML code:
<StackPanel Background="White" Margin="267,207,0,44" Grid.ColumnSpan="2">
<ScrollViewer Margin="30,30,0,30" Height="444">
<ItemsControl Name="ListCountries">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0,0,10,0" Width="100">
<TextBlock Text="{Binding Key}" Foreground="Red" />
<ItemsControl ItemsSource="{Binding}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0,10,0,0">
<TextBlock TextWrapping="Wrap" Text="{Binding title}" Foreground="Black" />
<TextBlock TextWrapping="Wrap" Text="{Binding desc}" Foreground="Gray" />
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</ScrollViewer>
</StackPanel>
I set the itemSource of the itemsControl named ListCountries, with a IEnumerable> and it prints a list of titles, followed by a list of objects of the OtherClass.
My problem is that , the columns that are filled sometimes are bigger than the height of the Stackpanel that they are inserted to, i want to be able to split my inner list of into columns.
as you can see in the image, Belgium country gets splited into 2 columns
right now all my countries are single column with vertical scroll.

You should use a GridView for this. Here's some code slightly modified from a Grid app in Visual Studio
<GridView
x:Name="itemGridView"
Grid.RowSpan="2"
Padding="116,137,40,46"
ItemsSource="{Binding Source={StaticResource groupedItemsViewSource}}"
SelectionMode="None"
Height="600">
<GridView.ItemTemplate>
<DataTemplate>
<Grid HorizontalAlignment="Left" Width="200">
<TextBlock Text="{Binding Description}" Foreground="{ThemeResource ListViewItemOverlayForegroundThemeBrush}" Style="{StaticResource TitleTextBlockStyle}" Height="60" Margin="15,0,15,0"/>
</Grid>
</DataTemplate>
</GridView.ItemTemplate>
<GridView.GroupStyle>
<GroupStyle>
<GroupStyle.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{Binding Title}" Style="{StaticResource SubheaderTextBlockStyle}" TextWrapping="NoWrap" />
</DataTemplate>
</GroupStyle.HeaderTemplate>
</GroupStyle>
</GridView.GroupStyle>
</GridView>
Here's a screenshot of what this looks like, with sample data

LongListSelector's performance is very bad. How to improve?

here is my code
<phone:LongListSelector ItemsSource="{Binding MovieTimeInDetailItems}"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch">
<phone:LongListSelector.ItemTemplate>
<DataTemplate>
<StackPanel Margin="24,0,0,12">
<TextBlock Text="{Binding Theater}" FontSize="34"/>
<ListBox ItemsSource="{Binding TimeItems}" HorizontalAlignment="Stretch" VerticalAlignment="Top" ScrollViewer.VerticalScrollBarVisibility="Disabled">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Grid Width="115" Margin="0,0,0,0">
<TextBlock Text="{Binding Time}"
TextWrapping="Wrap"
HorizontalAlignment="Left"
VerticalAlignment="Top"
FontSize="26"
Foreground="{StaticResource PhoneSubtleBrush}"/>
<Border Margin="92,0,0,0" HorizontalAlignment="Left" Width="{Binding Width}" Height="25" BorderThickness="1.5,0,0,0" BorderBrush="{StaticResource PhoneSubtleBrush}" />
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</DataTemplate>
</phone:LongListSelector.ItemTemplate>
</phone:LongListSelector>
In each LLS item contains a Listbox which display time list.
my question is ...
Can I display a time list without Listbox ? It seems Listbox cause the low performance.

Stretching of Border's width for ListBoxItem

I have wrote some class, named as Employe. Employees collection I set as source for ListBox WPF control. I have wrote such template for ItemTemplate:
<ResourceDictionary>
<DataTemplate x:Key="tmpEmploye">
<Border BorderThickness="3" BorderBrush="Gray" CornerRadius="5"
HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Path=Surname}"
HorizontalAlignment="Stretch" Margin="2"
FontWeight="Bold" TextWrapping="Wrap"/>
<TextBlock Text="{Binding Path=Name}"
HorizontalAlignment="Stretch" Margin="2"/>
<TextBlock Text="{Binding Path=Patronymic}"
HorizontalAlignment="Stretch" Margin="2"
TextWrapping="Wrap"/>
</StackPanel>
<TextBlock Text="{Binding Path=Post}" Foreground="Gray"
HorizontalAlignment="Stretch" Margin="2"
FontStyle="Italic" TextWrapping="Wrap"/>
</StackPanel>
</Border>
</DataTemplate>
</ResourceDictionary>
Each item has border. The border must be expanded according width of ListBox. I set HorizontalAlignment="Stretch" for Border, but it is not occured as I want.
How can I correct it?

Try this:
<ListBox Name="lbEmployees" ItemTemplate="{StaticResource tmpEmploye}"
HorizontalContentAlignment="Stretch"
/>
