I'm trying to make a two-column ListView. I'd like to avoid putting a GridView inside it because the design specs I'm matching are very simplistic. I can get the exact behavior that I want with an ItemsControl:
<ItemsControl ItemsSource="{Binding Items}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Key}" Grid.Column="0" />
<TextBlock Text="{Binding Value}" Grid.Column="1" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
This separates the item properties nicely between the two halves of the available space. However, a ListView with identical templates displays the properties right next to each other with no separation. Is there a way I can achieve the desired behavior in a ListView without a GridView?
For ItemsControl try setting the ItemContainerStyle of the ItemsControl to stretch the children horizontally:
<ItemsControl.ItemContainerStyle>
<Style TargetType="ContentPresenter">
<Setter Property="HorizontalAlignment" Value="Stretch"/>
</Style>
</ItemsControl.ItemContainerStyle>
For ListView try setting the ItemContainerStyle of the ListView to stretch the children horizontally:
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
</ListView.ItemContainerStyle>

I have the following XAML layout (ListBox where the Items are RadioButtons styled as ToggleButtons). The ListBox and the ToggleButton items scales and fills the ToggleButton items nicely to adapt to the window size. This is just as I want, but when I have the mouse over a ToggleButton in the ListBox, the style sets the Text to be bold. This is also what I want, but the problem is that it makes the button slightly bigger. When having the mouse over the ToggleButton item with the longest text the ViewBox refreshes and rescales all the ToggleButton controls. It looks like all the ToggleButtons makes a jump. How can I prevent such rescaling of the ToggleButtons still filling out the complete Grid Column and Row with the ListBox and its ToggleButton items?
<Viewbox Stretch="UniformToFill" Grid.Row="1" Grid.Column="0" VerticalAlignment="Stretch" Margin="5,0,0,15">
<Grid x:Name="LeftSide" Grid.Row="1" Grid.Column="0" VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="1*"/>
</Grid.RowDefinitions>
<ListBox Grid.Column="0" Grid.Row="0" Grid.RowSpan="10" ItemsSource="{Binding LeftPaneViewModelInfoItems, UpdateSourceTrigger=PropertyChanged}" Background="Transparent" SelectedItem="{Binding SelectedViewModelInfoItem}">
<ListBox.ItemContainerStyle>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="Background" Value="Transparent" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<ContentPresenter />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<RadioButton
Content="{Binding Text}"
GroupName="DisplayPage"
IsChecked="{Binding IsSelected, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}}}"
Style="{StaticResource RadioButtonToggleButtonStyle}"
>
</RadioButton>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</Viewbox>
Did not find a good solution. I ended up removing the bold setter property from the Mouse Over style.
I have something like this:
<ListBox ItemsSource="{Binding List}">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Property}" TextWrapping="Wrap" Grid.Column="0"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
And the problem I'm having is that the TextBlock will expand the Grid column (and the Listbox) when the text is too long, instead of wrapping it as expected. Maybe I don't understand the star-sizing concept of Grids completely, but the way I see it, since the column width is set to "1*" which means "the remaining space available", the Textblock should NOT try to expand beyond this width, and should wrap the text instead.
So how can I fix this problem? By the way, I need the Grid (or some other container) because there will be other components besides the Textblock. Also the ItemContainerStyle section is there so that the Listbox element occupies the whole space.
Thanks in advance!
Try to add ScrollViewer.HorizontalScrollBarVisibility="Disabled" to your ListBox.
you don't need column definitions if it will be just one, try with the following:
<ListBox ItemsSource="{Binding List}">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<TextBlock Text="{Binding Property}" TextWrapping="Wrap" HorizontalAlignment="Stretch"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I need to create a custom control containing a combobox whose popup will have the Name propeprty of the bound objects aligned to the left, and the CreatedDate property of the bound objects aligned to the right in each pop up item. Also the Name and the CreatedDate must not overlap. The Name of the object is of variable length
I tried solving this problem using a DataTemplate in the Combobox.ItemTemplate, inside the data template I have a grid with two columns aligned appropriately. The Grid's horizontal alignment is set to Stretch but for some reason the Grid doesn't fill out the available space in the popup. Does anyone know how to get around this and why it happens? I am using WPF 3.5.
<UserControl.Resources>
<CollectionViewSource x:Key="cvsProcessingSessionList" Source="{Binding ProcessingSessionList, ElementName=View}"/>
<Style TargetType="{x:Type ComboBox}"
BasedOn="{StaticResource {x:Static res:ObjectResources.LEComboBoxStyle}}">
<Setter Property="Margin" Value="5,3"/>
<Setter Property="HorizontalAlignment" Value="Stretch"/>
<Setter Property="VerticalAlignment" Value="Center"/>
</Style>
</UserControl.Resources>
<GroupBox x:Name="grbProcessingSession">
<GroupBox.Header>
<Bold>Processing Session:</Bold>
</GroupBox.Header>
<GroupBox.Content>
<ComboBox
x:Name="ccbProcessingSessionName"
ItemsSource="{Binding Source={StaticResource cvsProcessingSessionList}}"
Loaded="OnLoaded" TextSearch.TextPath="Name"
IsEditable="True" MaxDropDownHeight="500" >
<ComboBox.ItemTemplate>
<DataTemplate>
<Grid Background="Pink" HorizontalAlignment="Stretch" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="100" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" TextAlignment="Left" HorizontalAlignment="Left"
Margin="0,0,5,0" Text="{Binding Name}"/>
<TextBlock Grid.Column="1" TextAlignment="Right" HorizontalAlignment="Right"
Text="{Binding CreatedDate, StringFormat=dd/MM/yyyy}"/>
</Grid>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
</GroupBox.Content>
</GroupBox>
Just add this binding to your grid in yiour DataTemplate ...
Width="{Binding ActualWidth,
RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type ComboBoxItem}},
Mode=OneTime}"
Also for better effect, apply the background color to the ComboBoxItem and not to the grid...
<ComboBox.ItemContainerStyle>
<Style TargetType="{x:Type ComboBoxItem}">
<Setter Property="Background" Value="Pink"/>
</Style>
</ComboBox.ItemContainerStyle>
Whenever I want to do the same that you are asking I add:
<ComboBox ...>
<ComboBoxItem HorizontalContentAlignment="Stretch">
</ComboBoxItem>
</ComboBox>
The thing is that I place my custom DataTemplate inside the ComboBoxItem.
Maybe you should try it...
Actually, the better way is to set HorizontalContentAlignment="Stretch" at the ComboBox level. This will work even if width of ComboBox changes (e.g. if it is in resizable container).
However, be aware that this works in WPF and Silverlight 5 but don't work in some older versions of Silverlight.
I want to present a listbox with TextBlocks as items. When the user clicks/selects an item it changes into a TextBox for editing. As soon as the controls loses focus the item would turn back to a TextBlock.
The following XAML is almost working in that the TextBlock does turn into a TextBox when it's selected. It also turns back to a TextBlock if I select another item on the list. The problem is that if I move out of the listbox (in this case to the Add New text box) the list item stays as a TextBox.
The question ( WPF ListViewItem lost focus event - How to get at the event? ) looked promising but I can't make it work. I tried using the IsFocused property but then I wasn't able to edit the textbox because when I got into the textbox the listboxitem would go out of focus and thus turning back to a TextBlock before I had a chance to edit the text.
How can I make the TextBox turn back to TextBlock if the listbox/item loses the focus?
(Any other implementation that accomplishes the goal are also welcomed)

This doesn't answer your question, but gives an alternative solution by making a textbox look like a textblock when the listboxitem isn't selected:
<Page.Resources>
<ResourceDictionary>
<Style x:Key="ListBoxSelectableTextBox" TargetType="{x:Type TextBox}">
<Setter Property="IsHitTestVisible" Value="False" />
<Style.Triggers>
<DataTrigger Binding="{Binding IsSelected, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBoxItem}, AncestorLevel=1}}" Value="True">
<Setter Property="IsHitTestVisible" Value="True" />
</DataTrigger>
</Style.Triggers>
</Style>
</ResourceDictionary>
</Page.Resources>
<Grid>
<ListBox ItemsSource="{Binding Departments}" HorizontalContentAlignment="Stretch">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBox Margin="5" Style="{StaticResource ListBoxSelectableTextBox}" Text="{Binding Name}" BorderBrush="{x:Null}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
There are many ways you can do this:
Above answer
Create a TextBox style based on TextBoxBase such that when disabled, it makes the TextBox look like a TextBlock by setting the BorderThickness="0", Background="transparent"
Have both TextBlock and TextBox on each ListViewItem and using the above answer technique hide and show the TextBlock/TextBox accrodingly
I've got an ItemsControl which fills from top to bottom, but I can't get it's child items to occupy the whole width of the ItemsControl:
I basically need to stretch the green bits to fill the width of the control (as shown by the blue bits).
I've tried things like setting the HorizontalAlignment property of the template item to Stretch and I've even tried binding it's Width property to the ItemsControl Width, but neither worked.
Should be a straight forward one, but it's something I just can't quite figure out...
Edit: here's the ItemTemplate (the whole thing is the ItemTemplate which itself contains an ItemsControl which is bound to a list of child objects):
<DataTemplate>
<Border CornerRadius="5" Background="#ddd">
<StackPanel>
<TextBlock Text="{Binding Name}" FontSize="18" Foreground="#bbb"/>
<ItemsControl ItemsSource="{Binding PlugIns}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel HorizontalAlignment="Stretch" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Margin="10,0,10,10" Tag="{Binding}"
MouseEnter="StackPanel_MouseEnter">
<Border Child="{Binding Icon}" />
<TextBlock Text="{Binding Name}" />
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</Border>
</DataTemplate>
You need to configure the ListBoxItem HorizontalContentAlignment, you do this by using a Style object in the ListBox ItemContainerStyle as follows:-
<ListBox ....>
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListBox.ItemContainerStyle>
OK, so as I continued to build the app up, I figured out how to resolve this. Essentially, when I changed the template of the ItemsControl to support scrolling, the items spanned to fill horizontally :)
<ItemsControl>
<ItemsControl.Template>
<ControlTemplate>
<ScrollViewer Padding="{TemplateBinding Padding}">
<ItemsPresenter />
</ScrollViewer>
</ControlTemplate>
</ItemsControl.Template>
...
</ItemsControl>
