I would like to sort the second level of my TreeView. The sorting depends on two different conditions depending on the FieldType and the Order properties. In my case it is possible that the order increases or decreases by the user. The user uses arrow up and down buttons. How can I keep the list sortet if an item is added or removed and the user changes the Order property?
My current TreeView:
<TreeView Grid.Row="0" x:Name="tvImages" ItemsSource="{Binding SelectedTemplate.Images}">
<TreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type entities:TemplateImageDTO}" ItemsSource="{Binding FieldSections}">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Order, StringFormat=Image {0}}" Margin="0,3,0,0"/>
</StackPanel>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate DataType="{x:Type entities:FieldSectionDTO}">
<DockPanel LastChildFill="False" HorizontalAlignment="Stretch" Width="Auto">
<StackPanel DockPanel.Dock="Left" Orientation="Horizontal">
<TextBlock Text="{Binding FieldType, Converter={StaticResource enumConverter}}" Margin="0,3,0,0" />
<TextBlock Text=" - Field " Margin="0,3,0,0" />
<TextBlock Text="{Binding Order, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Margin="0,3,0,0" />
</StackPanel>
<StackPanel Orientation="Horizontal" DockPanel.Dock="Right" Margin="0,0,10,0">
<Button Width="24" Height="24" Style="{DynamicResource MahApps.Metro.Styles.MetroCircleButtonStyle}">
<iconPacks:PackIconFontAwesome Kind="AngleUpSolid" Foreground="{DynamicResource AccentColorBrush}" />
</Button>
<Button Width="24" Height="24" Margin="10,0,0,0" Style="{DynamicResource MahApps.Metro.Styles.MetroCircleButtonStyle}">
<iconPacks:PackIconFontAwesome Kind="AngleDownSolid" Foreground="{DynamicResource AccentColorBrush}" />
</Button>
</StackPanel>
</DockPanel>
</HierarchicalDataTemplate>
</TreeView.Resources>
</TreeView>
I found my Solution here: https://stackoverflow.com/a/19363888/6751312
After the user clicked the arrow up and down button, I increase and decrease the order property and resort the list.

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>
I'm filling a two WrapPanel with Buttons via DataTemplate but they all align vertically for some reason, what exactly is wrong here?
It doesn't matter if I set the Orientation property or not.

<ColumnDefinition />
</Grid.ColumnDefinitions>
<DockPanel Grid.Column="0" Height="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Grid}},Path=ActualHeight}">
<ScrollViewer VerticalScrollBarVisibility="Auto" DockPanel.Dock="Top" Height="520" Margin="5">
<WrapPanel>
<ItemsControl ItemsSource="{Binding Dashboards}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Width="120" Height="120" Margin="5" Command="{Binding DataContext.DashboardCommand, RelativeSource={RelativeSource AncestorType=ItemsControl}}" CommandParameter="{Binding}">
<TextBlock TextWrapping="Wrap" HorizontalAlignment="Center" Text="{Binding Name}" />
</Button>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
<Button Width="120" Height="120" Margin="5" Command="{Binding DashboardAddCommand}" Content="+" FontSize="100" />
</WrapPanel>
</ScrollViewer>
<StackPanel Height="100" Margin="5">
<Label>Dashboardname:</Label>
<TextBox Text="{Binding SelectedDashboard.Name}" />
<RadioButton Content="Sichtbar" Margin="0 10" IsChecked="{Binding SelectedDashboard.IsVisibleOnDashboard, UpdateSourceTrigger=PropertyChanged}" />
<Button Content="Dashboard löschen" Command="{Binding DashboardRemoveCommand}" />
</StackPanel>
</DockPanel>
<StackPanel Grid.Column="1" Margin="0">
<ScrollViewer VerticalScrollBarVisibility="Auto" Height="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type StackPanel}},Path=ActualHeight}">
<WrapPanel>
<ItemsControl ItemsSource="{Binding SelectedDashboard.DashboardItems}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Width="200" Height="120" Command="{Binding DataContext.DashboardItemCommand, RelativeSource={RelativeSource AncestorType=ItemsControl}}" CommandParameter="{Binding}" Margin="10">
<TextBlock TextWrapping="Wrap" HorizontalAlignment="Center" Text="{Binding Name}" />
</Button>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
<Button Width="200" Height="120" Content="+" FontSize="100" Command="{Binding DashboardItemAddCommand}" Margin="10" />
</WrapPanel>
</ScrollViewer>
</StackPanel>
</Grid>
</UserControl>
This is what the WrapPanel looks like:
The Add Button is always cut off somehow, too.
If you want to put the children of the ItemsControl horizontally in a WrapPanel, you need to tell the ItemsControl to use a WrapPanel for its children via an ItemsPanelTemplate:
<WrapPanel Orientation="Horizontal">
<ItemsControl ItemsSource="{Binding Dashboards}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button
Width="120"
Height="120"
Margin="5"
Command="{Binding DataContext.DashboardCommand, RelativeSource={RelativeSource AncestorType=ItemsControl}}"
CommandParameter="{Binding}"
>
<TextBlock
TextWrapping="Wrap"
HorizontalAlignment="Center"
Text="{Binding Name}"
/>
</Button>
</DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
<Button
Width="120"
Height="120"
Margin="5"
VerticalAlignment="Top"
Command="{Binding DashboardAddCommand}"
Content="+"
FontSize="100"
/>
</WrapPanel>
I don't know what you want to do with the button. My guess is that you want it to the right of the ItemsControl, and I aligned it to the top because that makes more sense to me.
Instead of
<ScrollViewer>
<WrapPanel>
<ItemsControl ItemsSource="{Binding Dashboards}">
<ItemsControl.ItemTemplate ... />
</ItemsControl>
<Button Content="+" ... />
</WrapPanel>
</ScrollViewer>
You can use
<ScrollViewer>
<ItemsControl ItemsSource="{Binding Dashboards}">
<ItemsControl.ItemTemplate ... />
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
<Button Content="+" ... /> <!-- A -->
</ScrollViewer>
<Button Content="+" ... /> <!-- B -->
WrapPanel is moved inside ItemsControl to layout dashboards.
You can put button somewhere else (same as #EdPlunkett I don't have a good idea where to put it): A - will let you to scroll button together with dashboards and B will keep button fixed, disregards scrolling.
I am new to windows 8.1 development.
I created the pages below with the button on the xaml page
GroupedItemsPage.xaml.cs
GroupedItemsPage.xaml
<Button Style="{StaticResource mystyle}" Click="ItemView_ItemClick" x:Name="Testing">
I was thinking that on page load of the xaml page I will be able to have access to the button property
by doing something like this .. Testing.property as we normally do in the windows development environment. This is not happening. I want to be able to style some buttons programmatically.
How can I get the property of the button in the .cs file?
Thanks. Here is the xaml page below.

It depends on your XAML. If your button is just a child element (i.e. part of your logical tree) or a named resource of your page, there'll be no problem, there's a code generation process on build, that creates required fields (in this case Button Testing) and finds required elements in InitializeComponent() generated method.
But if your button is a part of control template the only way to get reference to your element is GetTemplateChild() (if you're writing your own control, as this method is protected) or manually observing Visual Tree.
So, if you have a problem with the child element of your page, past all of your XAML markup here, as the line in the question above is not enough to find solution. But if you've defined button in control template, look at the second paragraph.
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"
/>
I have almost tried everything but for some reason it is not working
<StackPanel Orientation="Vertical" Grid.Row="1" Margin="5,30,5,10">
<TextBlock Text="View Options" FontSize="25" Style="{StaticResource PhoneTextNormalStyle}"/>
<ListBox HorizontalContentAlignment="Stretch" Background="Red" ItemsSource="{Binding Path=ViewOptions}" Margin="10">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock HorizontalAlignment="Center" TextAlignment="Center" Text="{Binding}" FontSize="35" Margin="20" Style="{StaticResource PhoneTextNormalStyle}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
Above XAML give me
How to move the textblock to center of listboxitem?
<StackPanel Orientation="Vertical" Grid.Row="1" Margin="5,30,5,10">
<TextBlock Text="View Options" FontSize="25" Style="{StaticResource PhoneTextNormalStyle}"/>
<ListBox x:Name="listBox" HorizontalContentAlignment="Stretch" ItemsSource="{Binding Path=ViewOptions}" Margin="10,30,10,10">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock HorizontalAlignment="Center" TextAlignment="Center" Text="{Binding}" FontSize="35" Margin="20" Style="{StaticResource PhoneTextNormalStyle}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
You need to change the HorizontalContentAlignment to center
<StackPanel Orientation="Vertical" Grid.Row="1" Margin="5,30,5,10">
<TextBlock Text="View Options" FontSize="25" Style="{StaticResource PhoneTextNormalStyle}"/>
<ListBox HorizontalContentAlignment="Center" Background="Red" ItemsSource="{Binding Path=ViewOptions}" Margin="10">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock HorizontalAlignment="Center" TextAlignment="Center" Text="{Binding}" FontSize="35" Margin="20" Style="{StaticResource PhoneTextNormalStyle}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I just tried this and it worked. Two possible differences:
My data source was a simple List<string>.
I removed the references to your styles (i.e. PhoneTextNormalStyle).
Are you binding to simple data?
Does PhoneTextNormalStyle specify left-alignment?
