I am trying to have a leftheader fixed in a scrollviewer but its height is not equal to the itemspresenter. I have given the code snippet.
<ItemsControl>
<ItemsControl.Template>
<ControlTemplate>
<ScrollViewer ScrollViewer.HorizontalScrollBarVisibility="Visible"
ScrollViewer.HorizontalScrollMode="Enabled"
HorizontalSnapPointsType="Mandatory">
<ScrollViewer.LeftHeader>
<Grid Width="190" Height="1000" Background="Black"/>
</ScrollViewer.LeftHeader>
<ItemsPresenter HorizontalAlignment="Left"
VerticalAlignment="Top"/>
</ScrollViewer>
</ControlTemplate>
</ItemsControl.Template>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<ItemsStackPanel Orientation="Horizontal" ItemsUpdatingScrollMode="KeepItemsInView">
</ItemsStackPanel>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.Items>
<Grid Width="1536" Height="1000" Background="Yellow"/>
<Grid Width="1536" Height="1000" Background="Red"/>
<Grid Width="1536" Height="1000" Background="Black"/>
</ItemsControl.Items>
</ItemsControl>
You need to scroll up to see the gap.
I have tested your code and reproduce your issue. I will report this issue to the related team. Currently one workaround to fix the content of LeftHeader is that you could wrap the Grid with Canvas just like the following code .
<ScrollViewer.LeftHeader >
<Canvas>
<Grid Width="190" Height="1000" Background="Red" />
</Canvas>
</ScrollViewer.LeftHeader>

I am looking to add WrapPanel inside my ListBox so that it's item wrap both vertically and horizentally. I was able to achieve this in Windows Phone 8 Sliverlight with Microsoft toolkit with below code;
Windows Phone 8
<ListBox x:Name="ListSection" ItemsSource="{Binding Section}" >
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel Orientation="Horizontal" ></toolkit:WrapPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="20">
<Image Source="{Binding ImagePath}" Width="80" Height="80"></Image>
<TextBlock Style="{StaticResource PhoneTextBlockBase}"
HorizontalAlignment="Center"
Foreground="Black"
Text="{Binding Header}"
FontWeight="Bold"
VerticalAlignment="Center" />
</StackPanel>
</DataTemplate>
I understand that Microsoft toolkit it not available in UWP, is there any possibility I could achieve such behavior in UWP?
UWP not working
<ListBox x:Name="ItemsListBox" ItemsSource="{Binding Section}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel HorizontalAlignment="Stretch"></StackPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<Image Source="{Binding ImagePath}" Width="80" Height="80"></Image>
<TextBlock HorizontalAlignment="Center"
Foreground="Black"
Text="{Binding Header}"
FontWeight="Bold"
VerticalAlignment="Center" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Thanks!
You must use ListView and ItemsWrapGrid as ItemsPanel
you can check the MSDN docs here with examples
https://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.controls.itemswrapgrid.aspx
This example is for GridView but is the same for ListView
<GridView>
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsWrapGrid Orientation="Horizontal"/>
</ItemsPanelTemplate>
</GridView.ItemsPanel>
you can use the property Orientation to set your items vertically or horizontally.
There is a port of the Toolkit's WrapPanel for UWP in the project WinRTXamlToolkit.
You can get it from NuGet.
Then in your Page add this prefix:
xmlns:toolkit="using:WinRTXamlToolkit.Controls"
Now you can use <toolkit:WrapPanel Orientation="Horizontal" ></toolkit:WrapPanel> as it was before.
#ARH you need to create a custom Panel class which inherits panel class and override MeasureOverride and ArrangeOverride methods.check out following links for reference.
https://msdn.microsoft.com/en-us/library/windows/apps/mt228347.aspx
http://www.visuallylocated.com/post/2015/02/20/Creating-a-WrapPanel-for-your-Windows-Runtime-apps.aspx
The WrapPanel is available from the Microsoft UWP Toolkit.
Here's some sample code (using v5.0.0):
...
xmlns:toolkit="using:Microsoft.Toolkit.Uwp.UI.Controls"
...
<ListView
Name="WrapPanelContainer"
Width="310" Height="200"
Margin="0,40,0,0"
HorizontalAlignment="Left"
Background="LightBlue"
IsItemClickEnabled="True"
>
<ListView.Resources>
<Style TargetType="ListViewItem">
<Setter Property="MinWidth" Value="0"/>
<Setter Property="MinHeight" Value="0"/>
<Setter Property="Padding" Value="0"/>
</Style>
</ListView.Resources>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel VerticalSpacing="10" HorizontalSpacing="10" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<Rectangle Fill="Red" Width="100" Height="50"/>
<Rectangle Fill="Blue" Width="200" Height="50"/>
<Rectangle Fill="Green" Width="50" Height="50"/>
<Rectangle Fill="Yellow" Width="150" Height="50"/>
</ListView>
NOTE: The ListItemView style here removes superfluous padding, allowing the WrapPanel spacing properties to be the control points for layout.
I have a StackPanel representing the top bar and a Hub representing books items. Both wrapped in the grid with two rows.
The problem is that in design mode hub content aligned properly to the top, just below my top bar. But in emulator it looks like all content aligned to the center of the hub.
In design time it looks like this:
But in emulator it looks like this:
Here is my XAML code:
<Page.Resources>
<DataTemplate x:Key="HubSectionHeaderTemplate">
<TextBlock Margin="0,0,0,-10" Text="{Binding}" FontSize="19" FontFamily="Open Sans" FontWeight="Light" FontStretch="ExtraExpanded" Foreground="#FF30323E">
<!--<TextBlock.RenderTransform>
<CompositeTransform/>
</TextBlock.RenderTransform>-->
</TextBlock>
</DataTemplate>
<!-- Grid-appropriate item template as seen in section 2 -->
<DataTemplate x:Key="Standard200x180TileItemTemplate">
<Grid Margin="0,0,15,15" Background="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}" VerticalAlignment="Top">
<Image Source="{Binding ImagePath}" Stretch="UniformToFill" AutomationProperties.Name="{Binding Title}" Height="165" Width="115"/>
<!--<TextBlock Text="{Binding Title}" VerticalAlignment="Bottom" Margin="9.5,0,0,6.5" Style="{ThemeResource BaseTextBlockStyle}"/>-->
</Grid>
</DataTemplate>
</Page.Resources>
<Grid x:Name="LayoutRoot">
<Grid.RowDefinitions>
<RowDefinition Height="60"/>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<StackPanel Grid.Row="0" Margin="0,-25,0,0">
<StackPanel.Background>
<ImageBrush ImageSource="Assets/CatalogTopBar.png" Stretch="UniformToFill"/>
</StackPanel.Background>
<Button x:Name="searchButton" Margin="0,25,-30,0" Height="15" Width="10" Content="" HorizontalAlignment="Right" VerticalAlignment="Center" BorderThickness="0" >
<Button.Background>
<ImageBrush ImageSource="Assets/noun_23695_cc.png" Stretch="Uniform"/>
</Button.Background>
</Button>
</StackPanel>
<Hub x:Name="Hub" x:Uid="Hub" Grid.Row="1" Background="White" Margin="0,25,0,0" VerticalContentAlignment="Top" VerticalAlignment="Top">
<HubSection x:Uid="HubSection2" Header="Популярные книги" Width="Auto"
DataContext="{Binding Groups[0]}" HeaderTemplate="{ThemeResource HubSectionHeaderTemplate}" >
<DataTemplate>
<GridView
Margin="0,-10,0,0"
ItemsSource="{Binding Items}"
AutomationProperties.AutomationId="ItemGridView"
AutomationProperties.Name="Items In Group"
ItemTemplate="{StaticResource Standard200x180TileItemTemplate}"
SelectionMode="None"
IsItemClickEnabled="True"

Ho-ho-ho... I finally managed to find the problem. After spending WEEKS!!! WEEKS, Carl! After spending few weeks I found out by accident that there is a MASSIVE "application name" <Hub.title> above my <Grid>.
It was not visible because of the white background and white font color of the text. By accidentally changing <RequestedTheme="Light"> I was finally able to see this text, because default font color changed to black. The text "application name" itself was not in my XAML source file, it was attached by localization facilities with x:Uid ="Hub" and corresponding value in resources.resw. After deleting x:Uid my layout returned to normal...
I am currently learning Windows Phone 8.1 app development. I am going through this Channel 9 series of video tutorials. They are useful but unfortunately are for Windows Phone 8, not 8.1 and so there are some things I can't follow. I am stuck in such a situation.
I want to have the following layout driven by some data:
So far I have the following code:
<Pivot x:Uid="Pvt">
<PivotItem Header="{Binding Animals.Title}">
<GridView ItemsSource="{Binding Animals.Items}">
<GridView.ItemTemplate>
<DataTemplate>
<!-- not sure what would go in here -->
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
</PivotItem>
</Pivot>
But not sure what element I'm supposed to have in the <DataTemplate>!
Gridview works fine in Windows Phone apps. Here is code from one of my apps in the app store. You need to set the size of the outer most 'Grid' of the DataTemplate. You won't be able to get the grids to fit the screen exactly unless you do some dynamic sizing after the UI is loaded.
<GridView Grid.Row="2" Margin="0,0,0,0"
ItemsSource="{Binding InfoTypeList}"
SelectionMode="None"
IsItemClickEnabled="True"
ItemClick="GridView_ItemClick">
<GridView.ItemTemplate>
<DataTemplate>
<Grid HorizontalAlignment="Left" Width="120" Height="120">
<Border Background="{ThemeResource PhoneAccentBrush}">
<Image Source="{Binding ImagePath}" Stretch="Uniform" Margin="10,10,10,20"/>
</Border>
<StackPanel VerticalAlignment="Bottom">
<TextBlock Text="{Binding Name}" Foreground="{ThemeResource ListViewItemOverlayForegroundThemeBrush}" Style="{StaticResource BaseTextBlockStyle}" FontSize="18" HorizontalAlignment="Center" FontWeight="SemiBold" IsTextScaleFactorEnabled="False"/>
</StackPanel>
</Grid>
</DataTemplate>
</GridView.ItemTemplate>
<GridView.ItemContainerStyle>
<Style TargetType="FrameworkElement">
<Setter Property="Margin" Value="20 20 0 0"/>
</Style>
</GridView.ItemContainerStyle>
</GridView>
EDIT:
I played around with it and you can get it to look more like your picture (fit the items to the screen) by wrapping your GridView in a Viewbox and then limiting the number of rows by adding this to your GridView:
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid Orientation="Vertical" MaximumRowsOrColumns="2" />
</ItemsPanelTemplate>
</GridView.ItemsPanel>
You will have to play around with your margins to get the correct spacing.
I am developing an application and I have an image control that displays however many images are stored in the database. So I have got the images to display. However the images are displaying below the previous one and not next to the previous one.
(ignore the names next to the picture I have taken them out now).
So my question is what method can I use to get them aligned, I'm not sure what I need to search for in Google, everything I can think of doesnt bring back anything close to what I am looking for. The XAML code is below:
<Grid x:Name="LayoutRoot" Background="Transparent">
<!--Pivot Control-->
<phone:Pivot Title="Share This!">
<!--Pivot item one-->
<phone:PivotItem Header="All Photos">
<Grid>
<ListBox Height="559" HorizontalAlignment="Left" Margin="6,20,0,0" x:Name="lst_viewPhotos" VerticalAlignment="Top" Width="444" FontSize="30" ItemsSource="{Binding}" SelectionChanged="lst_viewPhotos_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0,10,0,0" >
<Image Source="{Binding}" HorizontalAlignment="Left" Height="100" Width="100"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</phone:PivotItem>
</phone:Pivot>
</Grid>
You can get them displaying alongside each other by setting the ItemsPanel
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<VirtualizingStackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
However I would recommend a GridView for this so that you can use a Wrapgrid which will reach the end of a Row or Column and wrap to a new Row or Column.
Something like this
<GridView>
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid Orientation="Horizontal" />
</ItemsPanelTemplate>
</GridView.ItemsPanel>
</GridView>
I need to create a vertical scrolling list view with grouping enabled as shown below:
This is what I currently have:
<common:VariableSizeListViewWithSelection ItemsSource="{Binding Source={StaticResource cvs}}"
ScrollViewer.VerticalScrollBarVisibility="Auto"
IsItemClickEnabled="True"
ItemTemplateSelector="{StaticResource summaryViewTemplateSelector}" >
<GroupStyle>
<GroupStyle.HeaderTemplate>
<DataTemplate>
<Grid Margin="0,0,0,2">
<TextBlock Grid.Column="0" Text="{Binding Title}" Margin="0,-11,10,10" Style="{StaticResource SubheaderTextBlockStyle}" TextWrapping="NoWrap" FontWeight="SemiBold" Foreground="#333333" />
</Grid>
</DataTemplate>
</GroupStyle.HeaderTemplate>
</GroupStyle>
<common:VariableSizeListViewWithSelection.GroupStyle>
<GroupStyle HidesIfEmpty="True">
<GroupStyle.HeaderTemplate>
<DataTemplate>
<Grid Background="LightGray" Margin="0">
<TextBlock Text='{Binding Title}' Foreground="Black" Margin="5" Style="{StaticResource HeaderTextBlockStyle}"/>
</Grid>
</DataTemplate>
</GroupStyle.HeaderTemplate>
<GroupStyle.Panel>
<ItemsPanelTemplate>
<WrapGrid Orientation="Horizontal" MaximumRowsOrColumns="4" Width="300" />
</ItemsPanelTemplate>
</GroupStyle.Panel>
</GroupStyle>
</common:VariableSizeListViewWithSelection.GroupStyle>
</common:VariableSizeListViewWithSelection>
But this is not working as expected and it creates a listview with correct grouping but with just one column like this:
Can you please point me as to what am I doing wrong?
We took it offline for a bit and it seems like changing the ItemsPanel of the ListView to a StackPanel make this work. I have a feeling the default ItemsStackPanel should still support grouping, but perhaps not with a custom group layout panel. Maybe there is a way to reconfigure a GridView to scroll vertically and this could work too.
