I have two labels within my data template and I would like to see all the text within my label but the text is clipping off. I would like to see all the text and the text should be centered. I have increased the height of the labels but the text is not centered. This problem came about when I set the wrap panel max height to 20 and I need it to be 20. I would like to center the text vertically with the same font size. I have set the minimum height of the labels to 30 but the text is not centered vertically.
The clipping of the label within a list box
Set the Padding property of the Label elements to 0 or use TextBlocks:
<DataTemplate x:Key="dtTeamInGame">
<WrapPanel MaxHeight="20">
<Label x:Name="txtPath" Content="FirstName" MinWidth="35" FontStretch="Expanded" Padding="0"></Label>
<Label x:Name="txtPath2" Content="Surname" MinWidth="125" Padding="0"></Label>
</WrapPanel>
</DataTemplate>

I have the following markup:
<StackPanel Grid.Row="0" Orientation="Horizontal">
<StackPanel Orientation="Horizontal" Visibility="{Binding OrgListVisibility}">
<Label Content="Org:" />
<ComboBox ItemsSource="{Binding OrgSelectList, NotifyOnSourceUpdated=True}" SelectedValuePath="Key" DisplayMemberPath="Value" SelectedItem="{Binding OrgId}" />
</StackPanel>
<StackPanel Orientation="Horizontal" Visibility="{Binding BranchListVisibility}">
<TextBlock Text="Branch:" Style="{StaticResource FormLabel}" />
<ComboBox x:Name="BranchList" ItemsSource="{Binding BranchSelectList}" SelectedValuePath="Key" DisplayMemberPath="Value" SelectedItem="{Binding BranchId}" />
</StackPanel>
</StackPanel>
Yet when I run the app, only the text from the TextBlock is visible, and not that of the Label. The latter is in the Visual Tree, with a TextBlock deep down, but that is as far as I can see.
AS REQUESTED: Here is the style for FormLabel:
<Style TargetType="TextBlock" x:Key="FormLabel">
<Setter Property="Height" Value="20" />
<Setter Property="Margin" Value="10" />
<Setter Property="TextAlignment" Value="Right" />
<Setter Property="VerticalAlignment" Value="Center" />
</Style>
A SIMILAR PROBLEM:
I found an almost similar problem with a combobox when I bound it to a collection of instances of a generic class. The items' text simply did not show, but they were present in the comboboxes. Selecting on the one by knowing the position of my sought item correctly cascaded to the 2nd combobox, which had visible items, and I could see the correct but invisible item had been selected.
As soon as I change the item source to a list of non-generic objects, the items in the dropdown were visible again.
The code looks fine and as you have mentioned in the comments section that it takes layout space then it may very well happen that the color of your label and the background color of the containing layout be same.
To troubleshoot this, try giving some different background and foreground colors e.g. red or blue to the Label. Hope this helps
Ctrl+Q -> Live Visual Tree
Then hit the "pick element" button and select your label. Check the following properties:
Visibility
Opacity
Content
Also check the child elements of the Label. Setting the Content should result in a tree like this:
If a default style has changed the control template, you might not see the TextBlock as a child here. Also drill into the TextBlock and make sure it has the right Text property, then make sure it and all its parents have the right Opacity and Visibility . Also make sure that the inner TextBlock has space allocated to it by selecting it and turning on the highlighting feature in the live visual tree window.
Can you try this code to see if it works?
<Grid Grid.Row="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0"
Orientation="Horizontal" Visibility="{Binding OrgListVisibility}">
<Label Content="Org:" />
<ComboBox ItemsSource="{Binding OrgSelectList, NotifyOnSourceUpdated=True}"
SelectedValuePath="Key"
DisplayMemberPath="Value"
SelectedItem="{Binding OrgId}" />
</StackPanel>
<StackPanel Grid.Column="1"
Orientation="Horizontal" Visibility="{Binding BranchListVisibility}">
<TextBlock Text="Branch:" Style="{StaticResource FormLabel}" />
<ComboBox x:Name="BranchList"
ItemsSource="{Binding BranchSelectList}"
SelectedValuePath="Key"
DisplayMemberPath="Value"
SelectedItem="{Binding BranchId}" />
</StackPanel>
</Grid>
The Label would take up layout space while not being visible when its Visibility == Hidden. You should check and make sure that your application does not define a global style (one with no Key) for TargetType="Label" where this value could be set:
<Style TargetType="Label"> !!!note that this has no 'Key' associated
[...]
<Setter Property="Visibility" Value="Hidden" />
[...]
</Style>
This would not need to be in the same xaml file in order to be automatically applied, you should check the global dictionary or any other ResourceDictionary linked in the file.
I had the same problem. It turned out that the label Height was too small. Increased the height and its content became visible.
My WPF application has a ListBox whose ItemTemplate looks like this:
<DataTemplate x:Key="DomainTemplate" DataType="DomainViewModel">
<Border BorderBrush="{Binding Converter={StaticResource BrushConverter}, Path=IsSelected}"
BorderThickness="3"
Grid.Column="0"
Name="SelectedBorder"
Padding="5">
<Button Click="SelectDomain_Click"
FontSize="16"
FontWeight="Bold"
IsEnabled="{Binding Path=CurrentSiteIsValid, RelativeSource={RelativeSource AncestorType={x:Type c:DomainPicker}}}"
MinHeight="60"
Tag="{Binding Path=DomainId}"
Width="120">
<TextBlock Text="{Binding Path=Name}"
TextAlignment="Center"
TextWrapping="WrapWithOverflow" />
</Button>
</Border>
</DataTemplate>
The window's width is driven by the width of the ListBox. This is by design. There seems to a very large space between the vertical edges of the ListBox and the items in it. Using Snoop, I see that the ListBoxItem contains a Border that is the same width as the ListBox, has a Margin of 0, and Padding set to 2,0,0,0.
The Border contains a ContentPresenter whose width is 29 units smaller than the Border that contains it. The Padding on the Border would seem to account for 2 of the units. Its Margin is 0 and it has no padding property.
I actually would like to make this window a bit narrower if I can without making the Buttons in the template any narrower. Where is that 29 unit space coming from? Is there any way to change its size?
I've ran into this problem too in which I used a WrapPanel as the ListBox's ItemPanel, and i ended up with a gap between items in certain cases due to the problem you mentioned. Here is the fix:
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="Padding" Value="0"/>
</Style>
</ListBox.ItemContainerStyle>
im trying to make a week scheduler
so for each day i have a listbox with a grid as its itemspaneltemplate , and each individual session gets its row and rowspan from the database and its working very well
the problem is when i have a short appointment so the rowspan is only 2 or 3 and the content is longer, in that case the rows containing the appointment grow to accommodate the larger content
i don't want that, id rather the appointments reflect their time span even if i don't see all data
i tried many combinations of answers that i found online
heres the whole markup
<ListBox Name="lsbTasks" Loaded="lsbTasks_Loaded_1" HorizontalContentAlignment="Stretch" ScrollViewer.HorizontalScrollBarVisibility="Disabled" VerticalContentAlignment="Stretch" >
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<Grid Initialized="Grid_Initialized_1" Background="Thistle" IsSharedSizeScope="True"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ItemsControl.ItemContainerStyle>
<Style>
<Setter Property="Grid.Row" Value="{Binding BusyFrom,Converter={StaticResource BusyFromConverter}}" />
<Setter Property="Grid.RowSpan" Value="{Binding BusyMinutes,Converter={StaticResource BusyMinutesConverter}}" />
<Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto" />
</Style>
</ItemsControl.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<ScrollViewer ScrollViewer.CanContentScroll="True" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.IsDeferredScrollingEnabled="True">
<StackPanel Background="Purple" PreviewMouseDown="DockPanel_PreviewMouseDown_1">
<TextBlock TextAlignment="Center" TextWrapping="Wrap" Text="{Binding SessionPlace}" Foreground="Thistle" DockPanel.Dock="Bottom" />
<TextBlock TextAlignment="Center" TextWrapping="Wrap" Text="{Binding ClientName}" Foreground="White" FontWeight="Bold" DockPanel.Dock="Top" />
<TextBlock TextAlignment="Center" TextWrapping="Wrap" Text="{Binding OppositionName}" Foreground="White" DockPanel.Dock="Top" />
<TextBlock TextAlignment="Center" TextWrapping="Wrap" Text="{Binding SubjectName}" Foreground="Thistle" />
</StackPanel>
</ScrollViewer>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
and heres the initialization code
Private Sub Grid_Initialized_1(sender As Grid, e As EventArgs)
Dim mnts = MyWorkDaySpan.TotalMinutes
For i = 1 To mnts / 10
Dim rd = New RowDefinition With {.Height = New GridLength(1, GridUnitType.Star)}
'rd.SharedSizeGroup = "RowGroup"
sender.RowDefinitions.Add(rd)
Next
End Sub
but still the rows are uneven, as proven by the gridlines
id appreciate any help or guidance
You should use a different Panel, perhaps a Canvas and bind the Canvas.Top and Height properties in the ListBoxItem style.
Another alternative would be to write a custom Panel class ("CalendarPanel"), which defines two attached properties BusyFrom and BusyMinutes and arranges its child elements according to the values of these properties.
I'm developing an app that presents a timetable, that looks like this:
However, I have several problems with it:
When there are too many items (minutes) to display in 1 row it
should be broken automatically in several rows (e.g. all rows after
06 should be wrapped)
I don't know where the spacing around minute items comes from. It's not
item`s margin.
When scrolling the timetable list with finger, it only gets scrolled if no minute box is touched. Otherwise the minute box moves a bit, not the
entire timetable list.
The timetable list is bound to an ObservableCollection of TimetableHour instaces:
public class TimetableHour
{
public sbyte Hour { get; set; }
public IList<TimetableItem> Items { get; set; }
public string HourString
{
get { return Hour.ToString("00") + ":"; }
}
}
and the XAML page:
<Style TargetType="ListView" x:Key="TimetableListViewStyle">
<Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Hidden" />
<Setter Property="Margin" Value="0,0,60,0" />
<Setter Property="ItemTemplate">
<Setter.Value>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBox Text="{Binding HourString}"
Width="60" Height="50"
TextAlignment="Center"
Background="CornflowerBlue" Foreground="White" BorderThickness="0"
FontSize="23"
Padding="10">
</TextBox>
<GridView ItemsSource="{Binding Items}" Height="Auto" SelectionMode="None" IsTapEnabled="False" IsHoldingEnabled="False" >
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid Orientation="Horizontal" />
</ItemsPanelTemplate>
</GridView.ItemsPanel>
<GridView.ItemTemplate>
<DataTemplate>
<StackPanel Background="LightSkyBlue" Width="60" Height="50">
<TextBlock Text="{Binding Minute}" HorizontalAlignment="Center" FontSize="17" FontWeight="Medium" Margin="0,2,0,0"></TextBlock>
<TextBlock HorizontalAlignment="Center">Tip</TextBlock>
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
</StackPanel>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
<ListView Grid.Row="2" Grid.Column="2" ItemsSource="{Binding Timetable}"
Style="{StaticResource TimetableListViewStyle}"
SelectionMode="None" />
Ok, so I figured them out:
To make the minutes items wrap I needed to specify the exact width
of the GridView that is used to display them. Alternatively I can use a Grid instead of a StackPanel, to allow to use all available space - see GridView width inherited from parent
To control the spacing around GridView items you need to define the
ItemContainerStyle as described here:
Windows8 ListView and space between items
To achieve this I can set IsSwipeEnabled="False" on the GridView.
I have a WPF listbox which displays messages. It contains an avatar on the left side and the username and message stacked vertically to the right of the avatar. The layout is fine until the message text should word wrap, but instead I get a horizontal scroll bar on the listbox.
I've Googled and found solutions to similar issues, but none of them worked.
<ListBox HorizontalContentAlignment="Stretch" ItemsSource="{Binding Path=FriendsTimeline}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Border BorderBrush="DarkBlue" BorderThickness="3" CornerRadius="2" Margin="3" >
<Image Height="32" Width="32" Source="{Binding Path=User.ProfileImageUrl}"/>
</Border>
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Path=User.UserName}"/>
<TextBlock Text="{Binding Path=Text}" TextWrapping="WrapWithOverflow"/> <!-- This is the textblock I'm having issues with. -->
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Contents of the TextBlock can be wrapped using property TextWrapping.
Instead of StackPanel, use DockPanel/Grid.
One more thing - set ScrollViewer.HorizontalScrollBarVisibility property to Disabled value for the ListBox.
Updated Hidden to Disabled based on comment from Matt. Thanks Matt.
The problem might not be located in the ListBox. The TextBlock won't wrap, if one of the parent controls provides enough space, so that it hasn't the need to wrap. This might be caused by a ScrollViewer control.
If you want to prevent TextBlock to grow, and you want it to just fit in the size of the listbox, you should set the width of it explicitly.
In order to change it dynamically, it means not a fix value, but you need to bind it to its proper parent element in the visual tree. You can have something like this:
<ListBox ItemsSource="{Binding MyItems}" Name="MyListBox">
<ListBox.Resources>
<Style TargetType="ListBoxItem">
<Setter Property="Width"
Value="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ScrollContentPresenter}, Path=ActualWidth}" />
</Style>
</ListBox.Resources>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Title}" TextWrapping="Wrap" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
If it does not work, try to find the proper elements (which has to be binded to what) with the Live Visual Tree in Visual Studio.
