If you put the textblock in a canvas, that will not clip.

How to update TabControl resources?

I have a tab control in my view, bound to an observable collection. But when I call RaisePropertyChanged on it nothing gets updated. The tabs enabled do, but the views inside the tabs do not. How do I refresh the views in my Data templates?
<TabControl IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding DeviceListViewModel.SelectedDevice.TabViewModelsCollection, UpdateSourceTrigger=PropertyChanged}" SelectedItem="{Binding DeviceListViewModel.SelectedDevice.SelectedTabItemVm}" >
<TabControl.Resources>

<local:HomeTab/>
</DataTemplate>
<DataTemplate DataType="{x:Type vms:ConfigurationViewModel}">
<Grid>
<local:ConfigurationFileView Visibility="{Binding Configuration, TargetNullValue=Collapsed, FallbackValue=Visible}"/>
<local:ErrorTab Visibility="{Binding Path= Configuration, TargetNullValue=Visible, FallbackValue=Hidden}"/>
</Grid>

actually i can't understand why doesn't update your view, i think you must show me your behind code.
any way you can try:
tabControl.UpdateLayout();
and
tabControl.UpdateDefaultStyle();

Why are ListView and grouped CollectionViewSource not showing any items?

Here is code (minified):

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
DataContext="{Binding HubViewModel, Source={StaticResource Locator}}"
mc:Ignorable="d" Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">

</Grid>
</Border>
</DataTemplate>

</Page.Resources>
<ListView AutomationProperties.AutomationId="ItemListViewSection4"
AutomationProperties.Name="Items In Group"
SelectionMode="None"
IsItemClickEnabled="True"
ItemsSource="{Binding Source={StaticResource CollectionViewSourceCategories}}"
ContinuumNavigationTransitionInfo.ExitElementContainer="True"
ItemTemplate="{StaticResource DefaultItemTemplate}" AllowDrop="True">
<ListView.GroupStyle>
<GroupStyle HidesIfEmpty="True">
<GroupStyle.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}" />
</DataTemplate>
</GroupStyle.HeaderTemplate>
</GroupStyle>
</ListView.GroupStyle>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
</ListView>
As you can see, the CollectionViewSource is binded to the ListView and its IsSourceGrouped property is set to True. Categories contains 2 categories with 3 items in each category. But the ListView doesn't show anything, it's totally empty. What's wrong?

you need to add an itemPresenter in the GroupStyle.
<ListView Name="MyList" ItemsSource="{Binding Source={StaticResource CollectionViewSourceCategories}}" Grid.Row="1" Grid.Column="0">
<ListView.GroupStyle>
<GroupStyle>
<GroupStyle.ContainerStyle>
<Style TargetType="{x:Type GroupItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type GroupItem}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
<!-- ItemsPresenter -->
<ItemsPresenter />
<TextBlock Text="{Binding Name}" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</GroupStyle.ContainerStyle>
</GroupStyle>
</ListView.GroupStyle>
<ListView.View>
<GridView>
<GridView.Columns>
<GridViewColumn Header="NAME" DisplayMemberBinding="{Binding name}" />
</GridView.Columns>
</GridView>
</ListView.View>
</ListView>
Something else that might be helpful if you're grouping items Is to add a PropertyGroupDescription to your collectionViewSource:
First add this to your declarations:
xmlns:dat="clr-namespace:System.Windows.Data;assembly=PresentationFramework" xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"
then your CollectionViewSource:
<CollectionViewSource x:Key="CollectionViewSourceCategories" Source="{Binding Categories}">
<CollectionViewSource.GroupDescriptions>
<dat:PropertyGroupDescription PropertyName="Categories" />
</CollectionViewSource.GroupDescriptions>
<CollectionViewSource.SortDescriptions>
<scm:SortDescription PropertyName="Names" />
</CollectionViewSource.SortDescriptions>
</CollectionViewSource>
This will group by your category, then sort by names. here's the link explaining it:
https://msdn.microsoft.com/en-us/library/ff407126(v=vs.100).aspx
hope this helps!

You have to bind to the View property of the CollectionViewSource:
ItemsSource="{Binding Source={StaticResource CollectionViewSourceCategories}, Path=View}"

WPF : How to bind Button's visibility inside ListBox ItemsControl using selecteditem information ?

I have a list box binds to a ObservableCollection of Items. Each listboxItem contains a few textblocks and a few buttons. I would like to show the buttons inside the listboxItem only when the listbox item is selected or hightlight. If the listbox item is not highlighted, the button should be hidden. I tried to use datatrigger to bind to the IsSelected property. However it does not work. Please advice. thanks

</Button>
</StackPanel>
</DockPanel>
</Grid>
</DockPanel>
</Grid>
</Border>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

I attached a simple example to show button in listbox item when you selected. it should have to bind as RelativeSource and have to use Converter
Example:
<Window.Resources>
<BooleanToVisibilityConverter x:Key="booleanVisibleConverter" />
</Window.Resources>
<Grid>
<ListBox ItemsSource="{Binding ObservableCollection}" Grid.Row="0" SelectedItem="{Binding Path=Item}"
SelectionMode="Single" IsSynchronizedWithCurrentItem="True" Margin="1" ScrollViewer.HorizontalScrollBarVisibility="Disabled" SelectedIndex="0">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Label Content="{Binding}" />
<Button Content=" X " Visibility="{Binding RelativeSource={RelativeSource AncestorType={x:Type ListBoxItem}}, Path=IsSelected, Converter={StaticResource booleanVisibleConverter}}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>

You can create a style to associate with each of your buttons as follows:
<Style TargetType="{x:Type Button}">
<Setter Property="Visibility" Value="Collapsed"/>
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource
Mode=FindAncestor, AncestorType={x:Type ListBoxItem}},
Path=IsSelected}" Value="True">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
</Style>

How Does This Grid App Template Scroll without a Scrollviewer? (C#/XAML Windows 8.1)

I've been trying to understand Scrollviewers, and thought I'd take a look at Microsoft's template for a Grid App for 8.1, whose content extends off the screen. What's odd is that there doesn't seem to even be a Scrollviewer in the XAML page. Can anyone tell me what is enabling the scrolling?

If we go check out the default GridView template and look for the ItemsPresenter we see it's embedded in a ScrollViewer at the template level. Since now we know there's one there, if we look up towards the top in the Setter declarations we've got some Properties available to us to interact with that ScrollViewer from the GridView itself by seeing;
<Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto"/>
<Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Disabled"/>
<Setter Property="ScrollViewer.HorizontalScrollMode" Value="Enabled" />
<Setter Property="ScrollViewer.IsHorizontalRailEnabled" Value="False" />
<Setter Property="ScrollViewer.VerticalScrollMode" Value="Disabled" />
<Setter Property="ScrollViewer.IsVerticalRailEnabled" Value="False" />
<Setter Property="ScrollViewer.ZoomMode" Value="Disabled" />
<Setter Property="ScrollViewer.IsDeferredScrollingEnabled" Value="False" />
<Setter Property="ScrollViewer.BringIntoViewOnFocusChange" Value="True" />
So if we wanted that GridView to not scroll anymore we could tell it not to like;
<GridView ScrollViewer.HorizontalScrollBarVisibility="Disabled"/>
since it's set to "Auto" at the template level by default.
That's the thing about templates, sometimes it just takes digging one level deeper. Hope this helps, cheers.
