I'm really going mad ... but the whole evening I'm trying to create a 3 column listbox. I want that the 3 columns are spread over the whole size of the listbox and not sticked together like they do when using the code below.
So, here's my XML
<ListBox Background="Red" HorizontalContentAlignment="Stretch"
ItemsSource="{Binding ListItems}"
>
<ListBox.ItemTemplate>
<DataTemplate>
<Grid HorizontalAlignment="Stretch" Background="Aquamarine">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="A"/>
<TextBlock Grid.Column="1" Text="B"/>
<TextBlock Grid.Column="2" Text="C"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Hope you can help me.
If you set the Width attribute of a ColumnDefinition to Auto that column will only use the minimum required width. Change the width of all 3 columns to *.
Also try setting the HorizontalAlignment attribute of the 3 TextBlocks to Center.
Right now I found a solution:

I've got a window with a ListBox containing TextBlocks in the template:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition/>
</Grid.RowDefinitions>
...
<ListBox x:Name="AnnotationsList" ScrollViewer.VerticalScrollBarVisibility="Visible" Grid.Row="1" Grid.ColumnSpan="3">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*"/>
<ColumnDefinition Width="20*"/>
</Grid.ColumnDefinitions>
<Label Content="{Binding DateAdded}" Grid.Column="0"/>
<TextBlock Text="{Binding Description}" TextWrapping="Wrap" Grid.Column="1"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
I expected the TextBlock to adjust the size, with both elements in the template filling the width together in 1/20 proportions.
Instead, the TextBlock never gets smaller and ListBox gets a horizonal scrollbar.
How can I keep the list scrollable vertically and make sure the text gets narrower and wraps if I resize the window?
As Clemens answered in the comments, HorizontalScrollBarVisibility has an option of Disabled, which doesn't affect just the visibility, but actually triggers the children elements to get limited by the horizontal size of the container.
When I put a Textbox in a grid column like below
<StackPanel>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" MinWidth="115"/>
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="90"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="hello"/>
<TextBox Grid.Column="1" />
<Button Grid.Column="2" Content="push me"/>
</Grid>
</StackPanel>
I get proper result, i.e. textbox width is get from parent grid
But when I type a long text, the textbox starts exceeding its column and it stops extending after several extra letters
To .Net 4.6.2, I get same result but changing to .Net 4.7.2 the problem is solved i.e. the textbox width is not changing.
My software is compiled .Net 4.0, is there a solution to solve this for lower .net than 4.7.2?
Tried Pavel's first idea: removing stackpanel and adding another grid row in, still not working in .net 4.6.2
Tried Pavel's second idea: making the width of first column "Auto" instead of "1*". This works, the textbox doesn't extend (.net 4.6.2), however I really wanted the first and second column be responsive to resize.
You can solve this be removing the StackPanel and adding RowDefinition to Grid. You can also set TextWrapping="Wrap" for TextBox for wrapping a long text
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="90"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Text="hello" MinWidth="115"/>
<TextBox Grid.Column="1" TextWrapping="Wrap"/>
<Button Grid.Column="2" Content="push me"/>
</Grid>
StackPanel Y dimension is constrained to content, it will be automatically expanded to its content, more details can be found at panels overview
To me this is a bug that Textbox text size can change its parent width (grid width). This is happening in VS2019 .Net 4->4.6.2 but not in and after .Net 4.7.2.
For anybody faces this problem, I found below workaround by defining an invisible grid which contains textblocks. I get the widths of columns and give them to controls placed in a StackPanel.
<some container>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" MinWidth="115"/>
<ColumnDefinition Width="3*" />
<ColumnDefinition MinWidth="90"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="0"/>
</Grid.RowDefinitions>
<TextBlock x:Name="C0" Grid.Column="0" />
<TextBlock x:Name="C1" Grid.Column="1" Margin="5"/>
<TextBlock x:Name="C2" Grid.Column="2" />
</Grid>
<StackPanel Orientation="Horizontal">
<TextBlock Width="{Binding ElementName=C0, Path=ActualWidth }" Text="hello" />
<TextBox Width="{Binding ElementName=C1, Path=ActualWidth }" Margin="5" />
<Button Width="{Binding ElementName=C2, Path=ActualWidth }" Content="push me"/>
</StackPanel>
</some container>
The margin should be the same for column in grid and control in StackPanel (see second column).
I want text in column 3 wrap and have no horizontal scrollbar. Why doesn't this work?
<ItemsControl x:Name="listMessages" ItemsSource="{Binding Messages}" Grid.IsSharedSizeScope="True">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="Column1"/>
<ColumnDefinition Width="Auto" SharedSizeGroup="Column2"/>
<ColumnDefinition Width="*" SharedSizeGroup="Column3"/>
<ColumnDefinition Width="Auto" SharedSizeGroup="Column4"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Text1" />
<TextBlock Grid.Column="1" Text="Text2" />
<TextBlock Grid.Column="2" Text="Very long text that should wrap to the next line, but it doesn't work" TextWrapping="Wrap"/>
<TextBlock Grid.Column="3" Text="Text4" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
Items take more width than is available to ItemsControl. Same problem is with ListBox.
I tried to add ScrollViewer.HorizontalScrollbarVisibility=Disabled both on ItemsControl and Grid, but this doesn't help.
The text will be wrapped if you don't set the SharedSizeGroup property:
<ColumnDefinition Width="*"/>
Text wrapping and shared size groups don't go well together. You may want to specify a fixed MaxWidth for the ColumnDefinition or the TextBlock.
I'm newer in wpf,recently i have a requirement need to create an listbox and when i practice in DataTemplate ,the issue comed.my layout code like below
<ListBox HorizontalAlignment="Stretch" HorizontalContentAlignment="Left">
<ListBoxItem HorizontalAlignment="Stretch">
<Grid ShowGridLines="True" Height="50">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Rectangle Grid.Row="0" Grid.ColumnSpan="2"
Width="200" Height="40" Fill="Gray"/>
</Grid>
</ListBoxItem>
</ListBox>
the begining,i set the width 100 on the first column,because the Rectange's width become to 200,so the first column width become more greater than 100,what happend when the grid to measue the child element?i am confused about it ,because i put the code in an commen state it run normally.any one tell me ,thanks
I need to display the following layout with a telerik PanelBar.
With the code below I was able to achieve everything except the 92% stuff in each panel.
XAML:
<UserControl.Resources>
<DataTemplate x:Key="PanelBarItemTemplate">
<Grid x:Name="grdCategory" ShowGridLines="True">
<Grid.RowDefinitions>
<RowDefinition Height="30"></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="60*"></ColumnDefinition>
<ColumnDefinition Width="40*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid x:Name="grdSubCategory" Grid.Column="0" Style="{StaticResource CategoryLeftStyle}" >
<Grid.RowDefinitions>
<RowDefinition Height="20"></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50*"></ColumnDefinition>
<ColumnDefinition Width="25*"></ColumnDefinition>
<ColumnDefinition Width="25*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding CategoryTitle}" Grid.Row="0" Grid.Column="0"/>
<HyperlinkButton Grid.Row="0" Grid.Column="1" Style="{StaticResource DetailLinkStyle}" Content="Details" Click="Home_Click"></HyperlinkButton>
<TextBlock Text="{Binding Score}" Grid.Row="0" Grid.Column="2"/>
</Grid>
<TextBlock Text="92%" Grid.Column="1" Grid.Row="0" Grid.RowSpan="2" FontSize="32" FontWeight="Bold"/>
</Grid>
</DataTemplate>
<telerik:HierarchicalDataTemplate x:Key="PanelBarHeaderTemplate"
ItemsSource="{Binding SubReports}"
ItemTemplate="{StaticResource PanelBarItemTemplate}">
<TextBlock Text="{Binding CategoryTitle}" />
</telerik:HierarchicalDataTemplate>
</UserControl.Resources>
<Grid x:Name="LayoutRoot">
<telerik:RadPanelBar x:Name="radPanelBar"
ItemTemplate="{StaticResource PanelBarHeaderTemplate}"
IsSingleExpandPath="False" >
</telerik:RadPanelBar>
</Grid>
in the xaml.cs file I provided the ItemsSource.
Can somebody help me out?
All that code works perfectly well for the individual items, but to place the 92% relative to those items (somewhat outside of the sub-items) you would need to also modify the ItemContainerStyle of RadPanelBar. Easiest way is to extract it in Blend, then look for the section under PanelBarItemTopLevelTemplate named ItemsContainer. This is a somewhat crude version, but I made a public property on my item called CalcInt that calculates the sum of a property on the SubReport items so it can be bound from the base item level. My modified code looks like so:
<Grid x:Name="ItemsContainer" Grid.Row="1" Visibility="Collapsed">
<telerik:LayoutTransformControl x:Name="transformationRoot">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<ItemsPresenter/>
<TextBlock Text="{Binding CalcInt}" FontSize="48" Grid.Column="1" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
</telerik:LayoutTransformControl>
</Grid>
I basically changed it from just containing an ItemsPresenter to a grid with some layout to display my extra-large TextBlock.
If you need a sample of the code or have any other questions feel free to hit me up on Twitter - #EvanHutnick.

Hi I think you need to define a converter : IValueConverter and bind to the Label so you can calculate the percentual.
