Hi I see there have been many questions about ListBox and filling the entire space for the DataTemplate but I still cannot get anything to work. What I have is a ListBox and the DataTemplate has a UserControl. How do I get my UserControl to stretch the data to fill the space?
MainWindow XAML snippet:
<ListBox x:Name="ConfiguredItemsList">
<ListBox.ItemTemplate>
<DataTemplate>
<local:ConfiguredItem DataContext="{Binding}" HorizontalContentAlignment="Stretch" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
UserControl XAML snippet:
<UserControl.Resources>
<local:ImagePathConverter x:Key="ImagePathConverter"/>
</UserControl.Resources>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="75" />
</Grid.ColumnDefinitions>
<Grid Grid.Column="0">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" x:Name="NameLabel" Text="Name:" />
<TextBlock Grid.Row="0" Grid.Column="1" x:Name="tbName" Text="{Binding Path=Name}" />
<TextBlock Grid.Row="1" Grid.Column="0" x:Name="DescriptionLabel" Text="Description: " />
<TextBlock Grid.Row="1" Grid.Column="1" x:Name="Description" Text="{Binding Path=Description}" />
<TextBlock Grid.Row="2" Grid.Column="0" x:Name="TimeLabel" Text="Time:" />
<TextBlock Grid.Row="2" Grid.Column="1" x:Name="Time" Text="{Binding Path=ChangeTime, StringFormat={}{0:h:mm tt}}" />
</Grid>
<Border Grid.Column="1" BorderThickness="1" BorderBrush="Black">
<Image Source="{Binding Path=WallpaperInfo, Converter={StaticResource ImagePathConverter}}" />
</Border>
</Grid>
Have you tried to set HorizontalContentAlignment to stretch on list box level?
<ListBox x:Name="ConfiguredItemsList" HorizontalContentAlignment="Stretch">
<ListBox.ItemTemplate>
<DataTemplate>
<local:ConfiguredItem DataContext="{Binding}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Note: I have set HorizontalContentAlignment property of ListBox instead of Item.

My UWP application has ListView with dynamic contents. I want to enable ScrollView when it's height reaches to the end of device height it runs(desktop/mobile). I don't want to set height/maximum height of ListView. Because it should display as it is.
I have tried like below. But it is not working. It works only if specify the height of ListView.
<Grid HorizontalAlignment="Stretch" >
<Grid.RowDefinitions >
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<ListView x:Name="ItemListView" Margin="0,0,0,0" ScrollViewer.VerticalScrollBarVisibility="Auto" Grid.Row="0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Width="Auto" >
<!--ListView ItemTemplate to fill-->
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="Padding" Value="0" />
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate>
<Grid >
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width=".8*"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Row="0" Grid.Column="0" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.RowSpan="2">
<TextBlock Text="{Binding SerialNum}" TextAlignment="Center" />
</StackPanel>
<StackPanel Grid.Column="1" Grid.Row="0" >
<TextBlock Text="{Binding XX}" TextAlignment="Center" />
</StackPanel>
<StackPanel Grid.Row="0" Grid.Column="2" Orientation="Vertical" >
<TextBlock Text="{Binding YY}" TextAlignment="Center" />
<TextBlock x:Name="tb_list_date" HorizontalAlignment="Center" Text="{Binding ZZ}" TextAlignment="Center" />
</StackPanel>
<StackPanel Grid.Row="0" Grid.Column="3">
<TextBlock Text="{Binding AA}" TextAlignment="Center" />
</StackPanel>
<StackPanel Grid.Row="0" Grid.Column="4" Grid.RowSpan="2" VerticalAlignment="Center" HorizontalAlignment="Center" >
<TextBlock Text="{Binding BB}" TextAlignment="Center"/> </StackPanel>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
The problem is that the Grid.RowDefinition is set to Auto height. This lets the controls in the row to use any height they need. This causes the ListView to stretch beyond the boundaries of the page and because its height is actually the full height of the list, it does not scroll (but you can't see the overflow).
To fix this, change the Grid.RowDefinition Height to *. This will give the control all available space in the Grid but not more than that:
<Grid HorizontalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
...
</Grid>
Here's my code:
<Grid x:Name="SourceGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Text="Headers" />
<TextBlock Grid.Row="0" Grid.Column="1" Text="Tags" />
<ItemsControl Grid.Row="1" Grid.ColumnSpan="2" ItemsSource="{Binding Path=AllHeaders.Fields}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding}" />
<ComboBox ItemsSource="{Binding ElementName=SourceGrid, Path=DataContext.Tags}" />
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
As you can see, I have a TextBlock and a ComboBox inside of a DataTemplate, which is inside of a StackPanel. What I want to do is put TextBlock in Column=0 of my grid, and a ComboBox into Column=1 of my grid. How can I do that? Grid.Column property is inaccessible in both TextBlock and ComboBox.
this is your new layout:
<Grid x:Name="SourceGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Grid.Row="0"
Grid.Column="0"
Text="Headers" />
<TextBlock Grid.Row="0"
Grid.Column="1"
Text="Tags" />
<ItemsControl Grid.Row="1"
Grid.ColumnSpan="2"
ItemsSource="{Binding Path=AllHeaders.Fields}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid x:Name="SourceGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding}"
Grid.Column="0" />
<ComboBox ItemsSource="{Binding Path=DataContext.Tags, RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type Grid},AncestorLevel=2}}"
Grid.Column="1" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
or
<Grid x:Name="SourceGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Grid.Row="0"
Grid.Column="0"
Text="Headers" />
<TextBlock Grid.Row="0"
Grid.Column="1"
Text="Tags" />
<ItemsControl Grid.Row="1"
Grid.ColumnSpan="2"
ItemsSource="{Binding Path=AllHeaders.Fields}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid x:Name="SourceGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding}"
Grid.Column="0" />
<ComboBox ItemsSource="{Binding Path=DataContext.Tags, RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ItemsControl}}}"
Grid.Column="1" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
I've the following xaml definition. The textblock inside the stackpanel is not wrapping.
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<toolkit:PhoneTextBox x:Name="NotesText" Grid.Row="0" Grid.ColumnSpan="2" Hint="Add Notes" AcceptsReturn="True" Height="290" VerticalScrollBarVisibility="Auto" TextWrapping="Wrap" />
<StackPanel Orientation="Horizontal" Grid.Row="1" Grid.Column="0" >
<CheckBox x:Name="showRequester" FontSize="{StaticResource PhoneFontSizeSmall}" HorizontalAlignment="Left" />
<TextBlock TextWrapping="Wrap" VerticalAlignment="Center" HorizontalAlignment="Left" Text="option_show_to_requester" />
</StackPanel>
<CheckBox Grid.Row="1" Grid.Column="1" Content="Mail To Technicain" FontSize="{StaticResource PhoneFontSizeSmall}" HorizontalAlignment="Right" />
</Grid>
What I should do to make it wrap ? Thanks.
Update:
Problem with the alignment when using data template for check box content.
You can solve this by Providing Width of TextBlock.
You don't need to put a checkBox and a TextBlock into a StackPanel. To make the CheckBox's content Wrap, just use ContentTemplate of CheckBox.
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<toolkit:PhoneTextBox x:Name="NotesText" Grid.Row="0" Grid.ColumnSpan="2" Hint="Add Notes" AcceptsReturn="True" Height="290" VerticalScrollBarVisibility="Auto" TextWrapping="Wrap" />
<!--Use ContentTemplate of CheckBox-->
<CheckBox Grid.Row="1" Grid.Column="0">
<CheckBox.ContentTemplate>
<DataTemplate>
<TextBlock Text="option_show_to_requester" TextWrapping="Wrap"/>
</DataTemplate>
</CheckBox.ContentTemplate>
</CheckBox>
<CheckBox Grid.Row="1" Grid.Column="1" Content="Mail To Technicain" FontSize="{StaticResource PhoneFontSizeSmall}" HorizontalAlignment="Right" />
</Grid>
for a simple example:
<Grid Grid.Row="1" x:Name="ContentRoot" Tapped="ContentRoot_Tapped">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<CheckBox Grid.Column="0">
<CheckBox.ContentTemplate>
<DataTemplate>
<TextBlock TextAlignment="Center" Text="wrap123123123123wrap" TextWrapping="Wrap"/>
</DataTemplate>
</CheckBox.ContentTemplate>
</CheckBox>
<CheckBox Grid.Column="1">
<CheckBox.ContentTemplate>
<DataTemplate>
<TextBlock Text="nowrap" TextWrapping="Wrap"/>
</DataTemplate>
</CheckBox.ContentTemplate>
</CheckBox>
</Grid>
And the run image is:
I have a Listbox control and I have an expander control in all the items so that user can expand each of the item. But when I expand few items and scroll it. some times the expander get collapse automatically.
<ListBox x:Name="listbox" ItemsSource="{Binding Persons}" Background="LightBlue"
ItemTemplate="{StaticResource PersonDataTemplate}"
ItemContainerStyle="{StaticResource ListBoxItemStyle}"
VirtualizingPanel.IsVirtualizing="True"
VirtualizingPanel.IsVirtualizingWhenGrouping="True"
HorizontalContentAlignment="Stretch">
<ListBox.GroupStyle>
<GroupStyle HeaderTemplate="{StaticResource GroupHeaderTemplate}" />
</ListBox.GroupStyle>
</ListBox>
and resources have
<DataTemplate x:Key="PersonDataTemplate" DataType="{x:Type local:Person}">
<Grid>
<Expander >
<Expander.Header>
<TextBlock Text="{Binding Name}"/>
</Expander.Header>
<!--This will take time to be instancied-->
<!--<local:TimeConsumingControl />-->
<!--Rest of the data template-->
<Border Margin="4" BorderBrush="Black" BorderThickness="1" MinHeight="40" CornerRadius="3" Padding="3">
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<!--<RowDefinition />-->
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Text="Name : " Grid.Row="0" FontWeight="Bold" HorizontalAlignment="Right" />
<TextBlock Grid.Column="1" Grid.Row="0" Text="{Binding Name}" />
<TextBlock Text=" - Age : " Grid.Column="2" Grid.Row="0" FontWeight="Bold"
HorizontalAlignment="Right" />
<TextBlock Grid.Column="3" Grid.Row="0" Text="{Binding Age}" />
</Grid>
</Border>
</Expander>
</Grid>
</DataTemplate>
How can I prevent the items from collapsing. I still want to use Virtualization.
I am implementing a headered table using grids above each other, so I can specify columns headers. There is one grid for headers, and one grid for every row in the table. It is not very practical, header widths has to be specified twice. Maybe I instead can have a ListView/DataGrid without all styling?
How can I get rid of this multi Grid approach?
Here is what I got:
<StackPanel Orientation="Vertical">
<Grid Margin="0, 10, 0, 0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="40" />
<ColumnDefinition Width="70" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0"
Text="header 1" />
<TextBlock Grid.Column="1" Grid.Row="0"
Text="header 2" />
</Grid>
<ItemsControl ItemsSource="{Binding Entities}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<Grid Margin="0, 10, 0, 0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="40" />
<ColumnDefinition Width="70" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0"
Text="{Binding Property1}" />
<TextBlock Grid.Column="1" Grid.Row="0"
Text="{Binding Property2}" />
</Grid>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
You can use Grid.IsSharedSizeScope attached property
<StackPanel Orientation="Vertical" Grid.IsSharedSizeScope="True">
<Grid Margin="0, 10, 0, 0">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="First" Width="40" />
<ColumnDefinition SharedSizeGroup="Second" Width="70" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0"
Text="header 1" />
<TextBlock Grid.Column="1" Grid.Row="0"
Text="header 2" />
</Grid>
<ItemsControl ItemsSource="{Binding Entities}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<Grid Margin="0, 10, 0, 0">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="First" />
<ColumnDefinition SharedSizeGroup="Second" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0"
Text="{Binding Property1}" />
<TextBlock Grid.Column="1" Grid.Row="0"
Text="{Binding Property2}" />
</Grid>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
