I have a sample code here. Here my list box first item is behaing like header of list box. So now i dont want to scroll header. and rest of item's should be scrollable.`

I've just started learning WPF. However, now I'm having issues with my UI (which remains empty). This is the code I'm using; What I'm trying to do is to display the properties of the River in the UI.
<Window.Resources>
<local:River x:Key="theRiver" Name="Colorado River" MilesLong="1450" />
<StackPanel x:Key="stackey" DataContext="theRiver">
<StackPanel.Resources>
<DataTemplate x:Key="key" DataType="{x:Type local:River}" >
<Border x:Name="bdr" BorderBrush="Blue" BorderThickness="3" CornerRadius="12" Padding="2">
<Grid Margin="5">
<TextBlock x:Name="txt" FontFamily="Bookman old style">
<Run Text="The"/>
<TextBlock Text="{Binding Name}"/>
<Run Text="is"/>
<TextBlock Text="{Binding MilesLong}" />
<Run Text="miles long." />
</TextBlock>
</Grid>
</Border>
<DataTemplate.Triggers>
<Trigger SourceName="bdr" Property="IsMouseOver" Value="True">
<Setter TargetName="bdr" Property="Background" Value="Red"/>
<Setter TargetName="txt" Property="Foreground" Value="Green"/>
<Setter TargetName="bdr" Property="CornerRadius" Value="40"/>
</Trigger>
</DataTemplate.Triggers>
</DataTemplate>
</StackPanel.Resources>
</StackPanel>
</Window.Resources>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<!--<StackPanel Grid.Column="1" Grid.Row="1" Margin="10" Background="Gold" DataContext="{StaticResource theRiver}>-->
<ContentControl Content="{StaticResource ResourceKey=stackey}" Grid.Column="1" Grid.Row="1" Margin="10" Background="Gold" />
</Grid>
There are a few issues in your code.
<StackPanel x:Key="stackey" DataContext="theRiver">
<StackPanel.Resources>
<DataTemplate x:Key="key" DataType="{x:Type local:River}" >
Here you want to provide an unnamed DataTemplate for the type that will be loaded into the ContentControl. The StackPanel wrapper here is unnecessary, as is the x:Key on the DataTemplate.
<ContentControl Content="{StaticResource ResourceKey=stackey}"
This says that the source for the ContentControl's content is the StackPanel you declared in your resources, rather than an instance of River.
Corrected/working code looks like:
<Window.Resources>
<local:River x:Key="theRiver" Name="Colorado River" MilesLong="1450" />
<DataTemplate DataType="{x:Type local:River}">
<Border x:Name="bdr"
BorderBrush="Blue"
BorderThickness="3"
CornerRadius="12"
Padding="2">
<Grid Margin="5">
<TextBlock x:Name="txt" FontFamily="Bookman old style">
<Run Text="The" />
<TextBlock Text="{Binding Name}" />
<Run Text="is" />
<TextBlock Text="{Binding MilesLong}" />
<Run Text="miles long." />
</TextBlock>
</Grid>
</Border>
<DataTemplate.Triggers>
<Trigger SourceName="bdr" Property="IsMouseOver" Value="True">
<Setter TargetName="bdr" Property="Background" Value="Red" />
<Setter TargetName="txt" Property="Foreground" Value="Green" />
<Setter TargetName="bdr" Property="CornerRadius" Value="40" />
</Trigger>
</DataTemplate.Triggers>
</DataTemplate>
</Window.Resources>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<!-- <StackPanel Grid.Column="1" Grid.Row="1" Margin="10" Background="Gold" DataContext="{StaticResource theRiver}> -->
<ContentControl Grid.Row="1"
Grid.Column="1"
Margin="10"
Background="Gold"
Content="{Binding Source={StaticResource theRiver}}" />
</Grid>
Just define the DataTemplate in Windows.Resources like below (remove the Stackpanel):
<DataTemplate x:Key="stackey" DataType="{x:Type local:River}" >
<Border x:Name="bdr" BorderBrush="Blue" BorderThickness="3" CornerRadius="12" Padding="2">
<Grid Margin="5">
<TextBlock x:Name="txt" FontFamily="Bookman old style">
<Run Text="The"/>
<TextBlock Text="{Binding Name}"/>
<Run Text="is"/>
<TextBlock Text="{Binding MilesLong}" />
<Run Text="miles long." />
</TextBlock>
</Grid>
</Border>
<DataTemplate.Triggers>
<Trigger SourceName="bdr" Property="IsMouseOver" Value="True">
<Setter TargetName="bdr" Property="Background" Value="Red"/>
<Setter TargetName="txt" Property="Foreground" Value="Green"/>
<Setter TargetName="bdr" Property="CornerRadius" Value="40"/>
</Trigger>
</DataTemplate.Triggers>
</DataTemplate>
and then bind your ContentControl like
<ContentControl Grid.Column="1" Grid.Row="1" DataContext="{StaticResource theRiver}" Content="{StaticResource theRiver}" ContentTemplate="{StaticResource stackey}" Margin="10" Background="Gold" />
I have ObservableCollection with items which I want to display in a ListBox.
Also I write a template for ListboxItem for correct display of my collection.
On this stage everything works fine.
in .cs
Sensors = new ObservableCollection<Sensor>();
...
lstBox.ItemsSource = Sensors;
in .xaml
...
<DataTemplate x:Key="SensorTileTemplate">
<Border>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="70"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Name}" Grid.Row="0" Grid.ColumnSpan="3"></TextBlock>
<Image Source="{Binding ImageModel.ImgSource}" Style="{StaticResource ImageGlowStyle}" Height="72" Grid.Row="1" Grid.Column="0"></Image>
<StackPanel Grid.Row="1" Grid.Column="1" Margin="5">
<TextBlock Text="IP:"></TextBlock>
<TextBlock Text="Port:"></TextBlock>
<TextBlock Text="Command port:"></TextBlock>
</StackPanel>
<StackPanel Grid.Row="1" Grid.Column="2" Margin="5">
<TextBlock Text="{Binding DeviceAddress}"></TextBlock>
<TextBlock Text="{Binding DeviceDataPort}"></TextBlock>
<TextBlock Text="{Binding DeviceControlPort}"></TextBlock>
</StackPanel>
</Grid>
</Border>
</DataTemplate>
<Style x:Key="ContainerStyle">
<Style.Triggers>
<DataTrigger Binding="{Binding IsSelected}" Value="True">
<Setter Property="ListBoxItem.Visibility" Value="Collapsed"/>
</DataTrigger>
</Style.Triggers>
</Style>
...
<ListBox Name="lstBox" Focusable="False"
SelectionChanged="lstBox_SelectionChanged"
HorizontalContentAlignment="Stretch"
ItemTemplate="{StaticResource SensorTileTemplate}"
ItemContainerStyle="{StaticResource ContainerStyle}">
</ListBox>
The problem appears when I need to group certain items using expander as a group container.
in .cs
...
ICollectionView view = CollectionViewSource.GetDefaultView(Sensors);
view.GroupDescriptions.Add(new PropertyGroupDescription("GroupNumber"));
lstBox.ItemsSource = view;
...
in .xaml
<!--Same Template and Style-->
...
...
<Style x:Key="GroupContainerStyle" TargetType="{x:Type GroupItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type GroupItem}">
<Expander IsExpanded="True">
<Expander.Header>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Group #" />
<TextBlock Text="{Binding Name}" />
</StackPanel>
</Expander.Header>
<Expander.Content>
<ItemsPresenter />
</Expander.Content>
</Expander>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
...
<ListBox Name="lstBox" Focusable="False"
SelectionChanged="lstBox_SelectionChanged"
HorizontalContentAlignment="Stretch"
ItemTemplate="{StaticResource SensorTileTemplate}"
ItemContainerStyle="{StaticResource ContainerStyle}">
<ListBox.GroupStyle>
<GroupStyle ContainerStyle="{StaticResource GroupContainerStyle}" />
</ListBox.GroupStyle>
</ListBox>
This code works and groups items but items become invisible.
So without grouping items display correctly but with grouping expanders show nothing in it.
I think there is something about ItemsPresenter in Expander but can't figure out what.
The problem was in one third party theme I use in my app. That theme has a ListBox template like:
<Style TargetType="{x:Type ListBox}">
...
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBox}">
<Grid>
<Border x:Name="Border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="2" Background="{DynamicResource ControlBackgroundBrush}" />
<ScrollViewer Margin="1" Style="{DynamicResource NuclearScrollViewer}" Focusable="false" Background="{x:Null}">
<StackPanel Margin="1,1,1,1" IsItemsHost="true" />
</ScrollViewer>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Background" Value="{DynamicResource DisabledBackgroundBrush}" TargetName="Border" />
<Setter Property="BorderBrush" Value="{DynamicResource DisabledBorderBrush}" TargetName="Border" />
</Trigger>
<Trigger Property="IsGrouping" Value="true">
<Setter Property="ScrollViewer.CanContentScroll" Value="false" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
So I use an ItemsPresenter instead of the StackPanel in that template and everything works now.
I'm using a listView based on itemTemplate.
So i need in my template to alternate the background color :
- fist row: white
- second row:gray
- third row: white
- forth: gray
this is my template:
<DataTemplate x:Key="ItemFlight" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="60"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Border Background="#28AADB" Margin="2">
<Image Source="{Binding Path=IsArrival, Converter={StaticResource BooleanToImageDisplayConverter}}" Width="30" Height="30" VerticalAlignment="Center" Margin="5"/>
</Border>
<Grid Grid.Column="1" VerticalAlignment="Center">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="4*"/>
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="6*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBlock Text="{Binding FlightName}" FontWeight="Bold" Grid.Column="0" Grid.Row="0" Margin="10" Style="{StaticResource MyTextBlockStyle}"/>
<TextBlock Text="{Binding ArrivalOrDepartDateTime, Converter={StaticResource DateTimeConverter}}" FontWeight="Bold" Grid.Column="0" Grid.Row="1" Margin="10" Style="{StaticResource MyTextBlockStyle}"/>
<TextBlock Text="{Binding Terminal, Converter={StaticResource StringUpperConverter}}" Grid.Column="1" Grid.Row="0" Margin="10" Visibility="{Binding Path=IsArrival,Converter={StaticResource BooleanToVisibilityReverseConverter}}" Style="{StaticResource MyTextBlockStyle}"/>
<TextBlock Text="{Binding CityInfo.Name}" Grid.Column="1" Grid.Row="0" Margin="10" Visibility="{Binding Path=IsArrival,Converter={StaticResource BooleanToVisibilityConverter}}" Style="{StaticResource MyTextBlockStyle}"/>
<TextBlock Text="{Binding DepartureTime}" Grid.Column="1" Grid.Row="1" Margin="10" Style="{StaticResource MyTextBlockStyle}"/>
<TextBlock Text="{Binding CityInfo.Name}" Grid.Column="2" Grid.Row="0" Margin="10" Style="{StaticResource MyTextBlockStyle}" Visibility="{Binding Path=IsArrival,Converter={StaticResource BooleanToVisibilityReverseConverter}}"/>
<TextBlock Text="{Binding Terminal, Converter={StaticResource StringUpperConverter}}" Visibility="{Binding Path=IsArrival,Converter={StaticResource BooleanToVisibilityConverter}}" Grid.Column="2" Grid.Row="0" Margin="10" Style="{StaticResource MyTextBlockStyle}"/>
<TextBlock Text="{Binding ArrivalTime}" Grid.Column="2" Grid.Row="1" Margin="10" Style="{StaticResource MyTextBlockStyle}"/>
<TextBlock Text="{Binding Status}" Grid.Column="3" Grid.Row="0" Grid.RowSpan="2" Margin="15" Style="{StaticResource MyTextBlockStyle}" Foreground="#EA6A1E" FontSize="20" TextWrapping="Wrap" />
</Grid>
</Grid>
</DataTemplate>
How Can I do this please??
I tried this and it works for me.
<Window x:Class="TryResponses.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<vm:MainWindowViewModel x:Key="MainWindowViewModel" />
</Window.Resources>
<Grid Background="LightGray" DataContext="{StaticResource MainWindowViewModel}">
<Grid.Resources>
<Style TargetType="ListViewItem">

<Trigger Property="ItemsControl.AlternationIndex" Value="0">

</Trigger>
<Trigger Property="ItemsControl.AlternationIndex" Value="1">
<Setter Property="Background" Value="LightGray" />
</Trigger>
</Style.Triggers>
</Style>
<DataTemplate DataType="system:String">
<!-- put your data template here -->
</DataTemplate>
</Grid.Resources>
<ListView ItemsSource="{Binding Items}" AlternationCount="2" />
</Grid>
I hope this will help.

You should use AlternationCount property and it works on ListBox,ListView or any other control that inherits from ItemsControl.
The property definition and two examples are included at
https://msdn.microsoft.com/en-us/library/system.windows.controls.itemscontrol.alternationcount%28v=vs.110%29.aspx)
To view more clearly the selected lines, you can try this : (don't take care about the colors and final render, i've not spent the necessary time to make it sexy)
<Grid DataContext="{StaticResource MainWindowViewModel}">
<Grid.Resources>
<local:FalseToCollapsedConverter x:Key="FalseToCollapsedConverter" />
</Grid.Resources>
<ListView ItemsSource="{Binding Items}" AlternationCount="2" HorizontalContentAlignment="Stretch">
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<VirtualizingStackPanel />
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.Resources>
<Style TargetType="ListViewItem">

<TextBlock Grid.Column="1" Text="V" Margin="4" Visibility="{Binding IsSelected, RelativeSource={RelativeSource AncestorType=ListViewItem, Mode=FindAncestor}, Converter={StaticResource FalseToCollapsedConverter}}" />
<Border Grid.ColumnSpan="2" Background="#5500FF00"
BorderBrush="Blue" BorderThickness="2"

I have adapted a TreeViewItemStyle to my need and it works great when I have hardcoded my TreeViewItems like so:
<TreeView Grid.Column="0"
HorizontalAlignment="Stretch"
Name="treeView1"
VerticalAlignment="Stretch" >
<TreeView.Items>
<TreeViewItem Header="McDonalds" IsExpanded="True">
<TreeViewItem.Items>
<TreeViewItem Header="Burger" IsExpanded="True" IsSelected="True">
<TreeViewItem.Items>
<TreeViewItem Header="Meat" />
</TreeViewItem.Items>
</TreeViewItem>
</TreeViewItem.Items>
</TreeViewItem>
<TreeViewItem Header="KFC" >
<TreeViewItem.Items>
<TreeViewItem Header="Chicken"/>
</TreeViewItem.Items>
</TreeViewItem>
<TreeViewItem Header="Hungry Jacks">
<TreeViewItem.Items>
<TreeViewItem Header="Onion Rings" />
</TreeViewItem.Items>
</TreeViewItem>
</TreeView.Items>
</TreeView>
(I cannot post images, so I must link to them)
Images of Differences
First image is perfect, but the second is created when I try to databind my TreeView. The code below works fine as far as Hierachical Data goes, but it displays differently than I want it to.
<TreeView DataContext="{Binding TopLevelCategories}">
<TreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type model:Category}" ItemsSource="{Binding Path=Category1}">
<TreeViewItem Header="{Binding Path=Name}" Tag="{Binding}" />
</HierarchicalDataTemplate>
</TreeView.Resources>
You can see the yucky effect that it creates.
What is going wrong?

From the looks of the image this might be a problem with the item container. When you bind a collection to some ItemsControl you should not put the container item inside the DataTemplate, the ItemsControl will wrap your DataTemplate in an appropriate container itself (in this case a TreeViewItem).
So since your DataTemplate has another container in it you end up with two,
I have a little issue.
I have a a ListBox that is bound to a list of object. These Objects have a property that can be set. I have in the LIstBox ItemTemplate (a datatemplate) a combobox that is about to the objects property and the combobox has some hardcoded values.
My problem is that when the list box is displayed and I click ont he combo, only the ListBoxItem is selected, The click never makes it to the combobox!
just to give you an idea.

Make sure you don't have IsHitTestVisible="False" on the ComboBox's style. Can you please post here the styles you're using?
I found the problem.
My ItemContainerStyle Template had a rectangle and i guess it was implying zindex somehow. When I expclicity told it to draw the content before the border and it's rectangle, it worked. i just had to add Panel.ZIndex="1" and it worked.
