I have ListBox and dynamic DataTempletes Items.
When TextBlock text wrapping, ListBox size is adding and size changing when unwrapping doesn't return to old value and remains un-changed.
I don't understand what is the problem. TextBlock size changed but not ListBox.

I am trying to align data with the headers in a WPF application. The headers a line up and spaced nicely. However, I cannot get the data items underneath to line up with the headers. Any suggestions?
I have been poking around a bit, but have not found a solution to my problem. I do have to stick with list box as it is part of the requirements. Also, I am new to WPF.
Here is what the output is:
And here is the xaml that I am using:
<Grid Grid.Row="2">
<ListBox ItemsSource="{Binding MyData}">
<ListBox.Template>
<ControlTemplate>
<StackPanel>
<Grid Grid.IsSharedSizeScope="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" x:Name="ToteNumber"></ColumnDefinition>
<ColumnDefinition Width="*" x:Name="Desription"></ColumnDefinition>
<ColumnDefinition Width="*" x:Name="Time"></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Tote Number" HorizontalAlignment="Center"/>
<TextBlock Grid.Column="1" Text="Description" HorizontalAlignment="Center"/>
<TextBlock Grid.Column="2" Text="Time" HorizontalAlignment="Center"/>
</Grid>
<ItemsPresenter></ItemsPresenter>
</StackPanel>
</ControlTemplate>
</ListBox.Template>
<ListBox.ItemTemplate>
<DataTemplate>

<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Property1}" HorizontalAlignment="Stretch"/>
<TextBlock Grid.Column="1" Text="{Binding Property2}" HorizontalAlignment="Stretch"/>
<TextBlock Grid.Column="2" Text="{Binding Property3}" HorizontalAlignment="Stretch"/>
</Grid>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
You need to set Grid.IsSharedSizeScope="True" on a parent panel and you need to identify the SharedSizeGroup on each column so it knows which column in your listbox template grid corresponds to which one in your itemtemplate.
Note that I think * width is treated as Auto when you apply Sharedsizegroup.
I use width auto and minwidth instead when I've done something similar.
You may find you need to bind width of each column to some parent measuring grid or calculate minwidth using a converter based on ViewportWidth of the scrollviewer in your listbox.
<Grid Grid.Row="2" Grid.IsSharedSizeScope="True">
<ListBox ItemsSource="{Binding MyData}">
<ListBox.Template>
<ControlTemplate>
<StackPanel>
<Grid Grid.IsSharedSizeScope="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" SharedSizeGroup="A" x:Name="ToteNumber"></ColumnDefinition>
<ColumnDefinition Width="*" SharedSizeGroup="B" x:Name="Desription"></ColumnDefinition>
<ColumnDefinition Width="*" SharedSizeGroup="C" x:Name="Time"></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Tote Number" HorizontalAlignment="Center"/>
<TextBlock Grid.Column="1" Text="Description" HorizontalAlignment="Center"/>
<TextBlock Grid.Column="2" Text="Time" HorizontalAlignment="Center"/>
</Grid>
<ItemsPresenter></ItemsPresenter>
</StackPanel>
</ControlTemplate>
</ListBox.Template>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<Border BorderThickness="1" BorderBrush="Black">
</Border>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" SharedSizeGroup="A"></ColumnDefinition>
<ColumnDefinition Width="*" SharedSizeGroup="B"></ColumnDefinition>
<ColumnDefinition Width="*" SharedSizeGroup="C"></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Property1}" HorizontalAlignment="Stretch"/>
<TextBlock Grid.Column="1" Text="{Binding Property2}" HorizontalAlignment="Stretch"/>
<TextBlock Grid.Column="2" Text="{Binding Property3}" HorizontalAlignment="Stretch"/>
</Grid>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
As I mentioned, I use a similar technique in some of my own markup. For that I put the headers grid and then the listbox with an itemtemplate in a stackpanel.
<StackPanel>
<Grid>
Headers
<ListBox>
ItemTemplate
</StackPanel>
Sounds like that doesn't suit whatever is driving your requirements though.
This question already has answers here:
ListViewItem won't stretch to the width of a ListView
(2 answers)
Closed 7 years ago.
I am trying to display some data from an Observable Collection to a ListView.
Binding is working fine. My only problem I cannot fix is the layout of the ListView.I use a Grid with 2 rows to split my View. The ListView is one the second row. I only try to use * for setting Columns and Rows as suggested in most sources. The code for the ListView is this.
<Grid Grid.Row="1" Margin="10,0,10,0" HorizontalAlignment="Stretch">
<ListView ItemsSource="{Binding Collection}" HorizontalAlignment="Stretch">
<ListView.ItemTemplate>
<DataTemplate>
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" HorizontalAlignment="Center" Text="{Binding Period}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
<TextBlock Grid.Column="1" HorizontalAlignment="Center" Text="{Binding Currency}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
<TextBlock Grid.Column="2" HorizontalAlignment="Center" Text="{Binding Date}" Foreground="{StaticResource ColorBrush}" FontSize="20" FontFamily="{StaticResource Family}"/>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
When I use HorizontalAlignment="Stretch" for the Grid that contains the ListView and the ListView itself the data is displayed on the left side without getting the whole width of parent View.
When I explicitly set Width to some value (i.e.380) it displays OK.
<Grid Grid.Row="1" Margin="10,0,10,0">
<ListView ItemsSource="{Binding Collection}" Width="380">
<ListView.ItemTemplate>
<DataTemplate>
<Grid Width="380">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" HorizontalAlignment="Center" Text="{Binding Period}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
<TextBlock Grid.Column="1" HorizontalAlignment="Center" Text="{Binding ValueInCurrency}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
<TextBlock Grid.Column="2" HorizontalAlignment="Center" Text="{Binding Date}" Foreground="{StaticResource ColorBrush}" FontSize="20" FontFamily="{StaticResource Family}"/>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
But I want to know a better way to not use implicit values, but *.
Try this. Add the following jus after </ListView.ItemTemplate>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
</ListView.ItemContainerStyle>
I populate a textblock with data from Service and I bind the data to Listbox and then display it in textblocks, so far so good. My problem is that I want each textblock content to be placed in certain space in certain column, but this doesn't seem to work as my text is just put in each line and is not alligned as it should be.
here is my code:
<Grid x:Name="BranchesGrid" Margin="12,0,-12,6" Grid.Row="2" Height="542" VerticalAlignment="Bottom">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="150" />
<ColumnDefinition Width="150"/>
</Grid.ColumnDefinitions>
<ListBox Height="530" HorizontalAlignment="Left" Margin="12,6,0,0" Name="listBox1" VerticalAlignment="Top" Width="456" Grid.ColumnSpan="4">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding ID}" FontSize="20" Grid.Column="0" Padding="55,10,5,10" HorizontalAlignment="Center"/>
<TextBlock Text="{Binding Name}" FontSize="20" Grid.Column="1" Padding="110,10,5,10" HorizontalAlignment="Center"/>
<TextBlock Text="{Binding City}" FontSize="20" Grid.Column="2" Padding="70,10,5,10" HorizontalAlignment="Center"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
Where seems to be the problem?
Try this:
<Grid x:Name="BranchesGrid" Margin="12,0,-12,6" Grid.Row="2" Height="542" VerticalAlignment="Bottom">
<ListBox Height="530" HorizontalAlignment="Left" Margin="12,6,0,0" Name="listBox1" VerticalAlignment="Top" Width="456" Grid.ColumnSpan="4">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="150" />
<ColumnDefinition Width="150"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding ID}" FontSize="20" Grid.Column="0" Padding="55,10,5,10" HorizontalAlignment="Center"/>
<TextBlock Text="{Binding Name}" FontSize="20" Grid.Column="1" Padding="110,10,5,10" HorizontalAlignment="Center"/>
<TextBlock Text="{Binding City}" FontSize="20" Grid.Column="2" Padding="70,10,5,10" HorizontalAlignment="Center"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
I try to create some correct XAML to arrange text in the ComboBox to the right, but I cannot.
Here is my XAMl...
Any clue what I am missing?
Thank you!
<ComboBox Height="25"
HorizontalAlignment="Left"
ItemsSource="{Binding NonArchivedSequences}"
SelectedItem="{Binding SelectedSequence}"
Margin="0,0,0,4"
Name="cbSequences"
VerticalAlignment="Top"
Width="504"
HorizontalContentAlignment="Stretch"
SelectionChanged="cbSequences_SelectionChanged"
Grid.Column="1">
<ComboBox.Resources>
<DataTemplate x:Key="DataTemplateSequenceData">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Margin="4,2,2,4"
TextWrapping="Wrap"
Text="{Binding Interval}"
d:LayoutOverrides="Width, Height"
VerticalAlignment="Center"
HorizontalAlignment="Left" />
<TextBlock Margin="4,2,2,4"
TextWrapping="Wrap"
Text="{Binding Name}"
d:LayoutOverrides="Width, Height" Grid.Column="1"
VerticalAlignment="Center"
HorizontalAlignment="Left" />
</Grid>
</DataTemplate>
</ComboBox.Resources>
<ComboBox.ItemTemplate>
<StaticResource ResourceKey="DataTemplateSequenceData"/>
</ComboBox.ItemTemplate>
</ComboBox>
Maybe HorizonalAllignment="Right" You have Left
Probably I'm just missing something obvious, but I can't get the image in my DataTemplate to align to the right in the Grid, so that when the window is stretched, the image is "pulled" to the right as well:
<Window.Resources>
<DataTemplate x:Key="PersonTemplate" DataType="Minimal.Client.Person">
<Border BorderBrush="Purple" BorderThickness="2" CornerRadius="2" Padding="5" Margin="5">
<Grid Margin="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" MinWidth="200"/>
<ColumnDefinition Width="Auto" MaxWidth="200"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column ="0" Orientation="Horizontal" >
<TextBlock FontFamily="Verdana" FontSize="16" FontWeight="Bold" Text="{Binding LastName}" />
<TextBlock FontFamily="Verdana" FontSize="16" Text=", " />
<TextBlock FontFamily="Verdana" FontSize="16" Text="{Binding FirstName}" />
</StackPanel>
<StackPanel Grid.Column="1" Orientation="Vertical" HorizontalAlignment="Right">
<Border BorderBrush="Black" BorderThickness="1">
<Image Source="{Binding Picture}" Width="180" Height="150" />
</Border>
</StackPanel>
</Grid>
</Border>
</DataTemplate>
</Window.Resources>
Any suggestions?
I think the problem is that you have set a MaxWidth of 200 for the second column (where the Image is contained). Therefore, the column will not be any wider than 200 pixels and the two columns will not use the complete available space. If you insert another column in between the two columns and make this one star-sized, the Image will be right-aligned:
<Grid Margin="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" MinWidth="200"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto" MaxWidth="200"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column ="0" Orientation="Horizontal" >
<TextBlock FontFamily="Verdana" FontSize="16" FontWeight="Bold" Text="{Binding LastName}" />
<TextBlock FontFamily="Verdana" FontSize="16" Text=", " />
<TextBlock FontFamily="Verdana" FontSize="16" Text="{Binding FirstName}" />
</StackPanel>
<StackPanel Grid.Column="2" Orientation="Vertical" HorizontalAlignment="Right">
<Border BorderBrush="Black" BorderThickness="1">
<Image Source="{Binding Picture}" Width="180" Height="150" />
</Border>
</StackPanel>
</Grid>
This way, it works for me. However, you should be careful when using StackPanels. They always take as much space as they need. And if they are not given that much space, part of the content will simply be hidden.
gehho.
Try taking out the "MaxWidth" from your second column definition, and setting the Width to "*".
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" MinWidth="200"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
This keeeps the explicit settings from positioning your second column to the left.
