I have a grid with two columns each with a width of 1* to be of equal widths. Inside the left-most column, I have a listview but for some reason I can't get the width to automatically stretch to the width of the grid column. I've tried all kinds of things like HorizontalContentAlignment="Stretch" and ScrollViewer.HorizontalScrollBarVisibility="Disabled" both of which were suggested as possible fixes to this issue... but they don't seem to address my issue. Here's my code:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*"></ColumnDefinition>
<ColumnDefinition Width="1*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<ListView ItemsSource="{Binding Path= Loads}" Grid.Column="0" MinHeight="20" MaxHeight="100" HorizontalAlignment="Left" HorizontalContentAlignment="Stretch" ScrollViewer.HorizontalScrollBarVisibility="Disabled" Margin="6,-3,0,0" SelectedItem="{Binding Path= CurrentLoad}">
<ListView.ItemTemplate>
<DataTemplate DataType="local:Loads">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
<Button Width="26" Height="26">
<StackPanel>
<Image Source="{Binding Path=Icon}" Width="24" Height="24" Stretch="Fill"></Image>
</StackPanel>
</Button>
<TextBlock Text="{Binding Path=Name}" FontSize="9" Margin="3,6,3,3"></TextBlock>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<StackPanel Margin="0,-2,6,0" Grid.Column="1"></StackPanel>
</Grid
<ListView HorizontalAlignment="Left"
Well, there's your problem.

i have create my own tree-view with multi column Headers using standard wpf controls
Dock Panel
DataGrid , Just for creating the columns and having sorting and resizing capabilities. The height of datagrid is only 25 , we only need to show columns not data here.
The TreeView Control with hierarchy
i have add the image just to understand the problem and the XAML code
The Account Type should be always align at the left no matter how many levels are expanded in the "first column"
somewhere in the xaml of the TreeViewItemTemplate i lost the idea.. Can anyone help me to fix the alignments
<DockPanel DataContext="{StaticResource cust}">
<Button Command="{Binding rld}" Content="reload" DockPanel.Dock="Top"/>
<!--Unbound DataGrid just to display the headers-->
<DataGrid Height="25" DockPanel.Dock="Top" ItemsSource="{Binding Customers}" AutoGenerateColumns="False" Margin="0,0,0,0">
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding Name}" Header="Name" x:Name="col0"></DataGridTextColumn>
<DataGridTextColumn Binding="{Binding AccountType}" Header="Account Type" x:Name="col1"></DataGridTextColumn>
</DataGrid.Columns>
</DataGrid>
<!--Actual Binding with Tree View and item Template to display the properties-->
<TreeView ItemsSource="{Binding Customers}" DockPanel.Dock="Top">
<TreeView.ItemTemplate>
<HierarchicalDataTemplate ItemsSource="{Binding rel}">
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="{Binding ElementName=col0,Path=ActualWidth}"></ColumnDefinition>
<ColumnDefinition Width="{Binding ElementName=col1,Path=ActualWidth}" ></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Name}" VerticalAlignment="Center"/>
<TextBlock Grid.Column="1" Text="{Binding AccountType}" VerticalAlignment="Center" />
</Grid>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
</TreeView>
</DockPanel>
The TreeView naturally indents child items, so its normal what you see.
A possible fix could be to set a negative left margin in the AccountType TextBlock with the same value of the indent, therefore neutralizing the gap.
You need to apply it only if its parent is expanded. This can easily be done modifying a bit your viewmodels.
<TextBlock Grid.Column="1" Margin="{Binding marginPropertyInVM}" Text="{Binding AccountType}" VerticalAlignment="Center"/>
You can limit the size of your first column by changing your template grids column definition to:
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="{Binding ElementName=col1,Path=ActualWidth}" ></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Name}" VerticalAlignment="Center"/>
<TextBlock Grid.Column="1" Text="{Binding AccountType}" VerticalAlignment="Center" />
</Grid>
This way the first column will only be allowed the remaining width once the 2nd column and indent have been allocated their space.
I have a grid with column definitions.
Whenever the text inside a column cell exceeds the designated width, it shrinks the left hand column down.
Here's an example
And this is my xaml markup
<ItemsControl Name="rfbItems" ItemsSource="{Binding}"
Style="{StaticResource contentItemsControl}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical" Width="Auto" HorizontalAlignment="Left" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0.3*" />
<ColumnDefinition Width="0.7*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Title}" Style="{StaticResource App_Content_Grid}" TextAlignment="Left" />
<TextBlock Grid.Column="1" Text="{Binding Description}" Style="{StaticResource App_Content_Grid_Subtle}" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
How should I restrict this behavior without losing responsiveness in the layout?
Also, if there is a better way to achieve what I'm trying to do here (inside the datatemplate), please feel free to share :)
Try setting margin and horizontal alignment to text boxes as below:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0.3*" />
<ColumnDefinition Width="0.7*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Margin="5" HorizontalAlignment="Stretch" Text="{Binding Title}" Style="{StaticResource App_Content_Grid}" TextAlignment="Left" />
<TextBlock Grid.Column="1" Margin="5" HorizontalAlignment="Stretch" Text="{Binding Description}" Style="{StaticResource App_Content_Grid_Subtle}" />
</Grid>
The Grid doesn't have a limited width unless you give your StackPanel a fixed width. Setting Width="123" should work, HorizontalAlignment="Stretch" might do it as well (untested).
I'm sorry for all your efforts, but I found a solution.
None of the answers worked for me, so feel free to find a fitting solution and I'll accept your answer.
<ItemsControl Name="rfbItems" ItemsSource="{Binding}"
Style="{StaticResource contentItemsControl}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical" Width="Auto" HorizontalAlignment="Left" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="125" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Title}" Style="{StaticResource App_Content_Grid}" TextAlignment="Left" />
<TextBlock Grid.Column="1" Text="{Binding Description}" Style="{StaticResource App_Content_Grid_Subtle}" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
The first column has a fixed width, that's why the second column can't expand anymore.
Is there possibility to display two TextBlock on a Grid ?
I tried, but i see only my first TextBlock.
Here is my XAML code :
<ListBox x:Name="ListBoxTiers" HorizontalAlignment="Left" VerticalAlignment="Top">
<ListBox.ItemTemplate>
<DataTemplate>
<Border Background="#FFDEDEDE" CornerRadius="10" Margin="10">
<StackPanel Orientation="Horizontal">
<Grid Height="89" Width="975">
<TextBlock x:Name="TxtBox_CodeTiers" TextWrapping="Wrap" Text="{Binding m_strCode}" Margin="12,23,479,30" />
<TextBlock x:Name="TxtBox_NomTiers" Margin="501,23,14,24" TextWrapping="Wrap" Text="{Binding m_strNom}"/>
</Grid>
</StackPanel>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Thanks a lot :)
Grid is the best UI container which supports orientation. You can modify your code in the below way.
<ListBox x:Name="ListBoxTiers" HorizontalAlignment="Left" VerticalAlignment="Top">
<ListBox.ItemTemplate>
<DataTemplate>
<Border Background="#FFDEDEDE" CornerRadius="10" Margin="10">
<Grid Height="89" Width="975">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock x:Name="TxtBox_CodeTiers" Grid.Column=0 TextWrapping="Wrap" Text="{Binding m_strCode}" />
<TextBlock x:Name="TxtBox_NomTiers" Grid.Column=1 TextWrapping="Wrap" Text="{Binding m_strNom}"/>
</Grid>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
You should have to adjust the column column width as per your requirement.
Both of your texts are drawn at the same location.
You can either add Grid columns/Raws or remove the grid completly and stay with the stackPanel
You should go over Panels Overview
I created my own simple statusbarcontrol with 3 TextBlocks. Now I would like that the first Textblock takes as much space as it has available. That I don't seem to get done.. Now it only takes the space needed to display the text.
XAML:
<StatusBar Background="{StaticResource GradientBrush}">
<StatusBar.ItemsPanel>
<ItemsPanelTemplate>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
</Grid>
</ItemsPanelTemplate>
</StatusBar.ItemsPanel>
<StatusBarItem HorizontalAlignment="Left"
HorizontalContentAlignment="Right">
<Border BorderThickness="1"
BorderBrush="Black"
Padding="5 0 5 0"
Background="White">
<TextBlock Text="{Binding Message, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
Foreground="{Binding TextColorMessage}"
Background="White"
/>
</Border>
</StatusBarItem>
<Separator Grid.Column="1" />
<StatusBarItem Grid.Column="2"
HorizontalAlignment="Right">
<TextBlock Text="{Binding Path=DatabaseName, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
</StatusBarItem>
<Separator Grid.Column="3" />
<StatusBarItem Grid.Column="4"
HorizontalAlignment="Right">
<TextBlock Text="{Binding Path=ComputerName}" />
</StatusBarItem>
Well this is pretty straight forward:
you had set the StatusBarItem HorizontalAlignment="Left" when it should be "strech", same for the HorizontalContentAlignment.
Also would suggest setting margin=0 on the border.
this is what i did so it will work for me:
<StatusBarItem HorizontalAlignment="Stretch"
HorizontalContentAlignment="Stretch">
<Border BorderThickness="1"
BorderBrush="Black"
Margin="0"
Padding="5 0 5 0"
Background="White">
<TextBlock Text="{Binding Message, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
Foreground="{Binding TextColorMessage}"
Background="White"/>
</Border>
</StatusBarItem>
if this is helpful please mark as answer
Try setting the StatusBarItem's HorizontalAlignment and HorizontalContentAlignment to Stretch.
Set the StatusBarItem's HorizontalContentAlignment to Stretch and the TextBlock's TextAlignment property to Right. (This second setting is only needed for the first StatusBarItem as it seems that you try to align the text to the right in it.)
StatusBar has only one HorizontalAlignment=Right item to effect, so you can get only the last item in wanted place. You can set statusBar's FlowDirection="RightToLeft" and add item in reversed order. Details: right placed items needn't StatusBarItem surrounded, but the left one need to be streched. Following code:
<StatusBar VerticalAlignment="Bottom" FlowDirection="RightToLeft"><!--flow right to left cause items right aligned-->
<!--make item's flow back left to right, avoid display disorder-->
<TextBlock x:Name="textBlock_status_R1" Text="111.147.168.20" Grid.Column="2" Margin="10,0" FlowDirection="LeftToRight"/>
<Separator/>
<TextBlock x:Name="textBlock_status_R2" Text="Working" Margin="10,0" FlowDirection="LeftToRight"/>
<Separator/>
<!--To fill rest space，need StatusBarItem packing and default HorizontalAlignment="Stretch"-->
<StatusBarItem FlowDirection="LeftToRight">
<TextBlock x:Name="textBlock_status_L1" Text="Information here."/>
</StatusBarItem>
</StatusBar>
I created user control with the textblock. But it will not wrap. This user control servers as a listboxitem.
<Grid x:Name="MainGrid" Height="Auto" Width="Auto">
<StackPanel Orientation="Horizontal">
<Image Height="50" Width="100" Stretch="Uniform" Name="image1" Source="{Binding Path=VideoImageUrl}" Margin="12,12,13,84" MouseLeftButtonDown="image1_MouseLeftButtonDown" MouseEnter="image1_MouseEnter" MouseLeave="image1_MouseLeave" />
<StackPanel Orientation="Vertical" >
<TextBlock TextWrapping="Wrap" Height="Auto" HorizontalAlignment="Left" Name="titleTextBox"
Text="{Binding Path=Title, Mode=TwoWay, ValidatesOnExceptions=true, NotifyOnValidationError=true}"
VerticalAlignment="Center" Width="Auto" FontSize="14" FontWeight="SemiBold" />
<StackPanel Orientation="Vertical" x:Name="StackPanelDetails">
<TextBlock Height="Auto" HorizontalAlignment="Left" Name="desciptionTextBox"
TextWrapping="Wrap"
Text="{Binding Path=Desciption, Mode=OneWay, ValidatesOnExceptions=true, NotifyOnValidationError=true}"
VerticalAlignment="Center" Width="Auto" />
<Line />
<ItemsControl x:Name="CustomItemsSource" ItemsSource="{Binding Path=LinksList}" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<TextBlock>
<Hyperlink NavigateUri="{Binding Path=TopicUrl}" RequestNavigate="Hyperlink_RequestNavigate" >
<TextBlock Text="{Binding Path=TopicName}" />
</Hyperlink>
</TextBlock>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</StackPanel>
</StackPanel>
</Grid>
A ListBox's default template does not automatically limit the width of its items, but instead uses a ScrollViewer, which shows a horizontal scrollbar when an item is wider than the ListBox.
You can remove the ScrollViewer by replacing the ListBox's Template:
<ListBox ...>
<ListBox.Template>
<ControlTemplate>
<StackPanel IsItemsHost="True"/>
</ControlTemplate>
</ListBox.Template>
...
</ListBox>
Another important thing to note is that a StackPanel in the top-level Grid won't properly resize the contained elements. In the following simplified example the text in the TextBlock is not wrapped because the containing StackPanel simply does not resize it as you expect:
<Grid>
<StackPanel Orientation="Horizontal">
<Image ... />
<Text TextWrapping="Wrap" Text=... />
</StackPanel>
</Grid>
This way it works as you expect:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Image ... />
<TextBlock Grid.Column="1" TextWrapping="Wrap" Text=... />
</Grid>
