I'm using VS2017 and I'm adding a checkbox to an ItemsControl's template. I'm seeing that the checkmark is a cross ("X") rather than a checkmark. Did they change this recently?
<ItemsControl ItemsSource="{Binding AllParams}" Foreground="White">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="25"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<CheckBox Height="15" Width="15" Grid.Column="0" Margin="2,0,10,0" />
<Button Grid.Column="1" Command="{Binding EditViewCommand}" ToolTip="{Binding Description}" Style="{StaticResource NavigationButtonStyle}">
<TextBlock>
<Run Text="{Binding DisplayName}"/>
</TextBlock>
</Button>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
Is there a setting to choose? What am I missing?

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.
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>
I have a listbox containing itemtemplate like this
<ListBox Name="lstCompany" Grid.Column="0" MinWidth="200" Grid.Row="1" HorizontalAlignment="Stretch" Margin="2,2,2,2" VerticalAlignment="Stretch" HorizontalContentAlignment="Stretch" ItemsSource="{Binding}" SelectionChanged="lstCompany_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<DockPanel>
<Grid Name="grid1" VerticalAlignment="Top" Margin="2" HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<StackPanel Orientation="Vertical" HorizontalAlignment="Stretch">
<TextBlock Text="{Binding [0]}" FontWeight="Bold" />
<TextBlock Text="{Binding [1]}"></TextBlock>
<StackPanel.ToolTip>
<ToolTip>asdf</ToolTip>
</StackPanel.ToolTip>
</StackPanel>
</Grid>
<StackPanel VerticalAlignment="Top" HorizontalAlignment="Right" DockPanel.Dock="Right">
<Button Content="X" Tag="{Binding [2]}" Width="20" Click="btnRemove_Click" Name="btnRemove1" HorizontalAlignment="Right"></Button>
</StackPanel>
</DockPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
This listbox is in first column of a grid which has a splitter.
Now problem is that I am not able to align the button to right side of listbox item.
One Grid is enough here. You only need one star-sized column (for content) and one Auto-sized column (for the button):
<ListBox Name="lstCompany" Grid.Column="0" MinWidth="200" Grid.Row="1" HorizontalAlignment="Stretch" Margin="2,2,2,2" VerticalAlignment="Stretch" HorizontalContentAlignment="Stretch" ItemsSource="{Binding}" SelectionChanged="lstCompany_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate >
<Grid Name="grid1" VerticalAlignment="Top" Margin="2" HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<StackPanel Orientation="Vertical" HorizontalAlignment="Stretch">
<TextBlock Text="{Binding [0]}" FontWeight="Bold"/>
<TextBlock Text="{Binding [1]}" ></TextBlock>
<StackPanel.ToolTip>
<ToolTip>asdf</ToolTip>
</StackPanel.ToolTip>
</StackPanel>
<StackPanel Grid.Column="1" VerticalAlignment="Top" HorizontalAlignment="Right">
<Button Content="X" Tag="{Binding [2]}" Width="20" Click="btnRemove_Click" Name="btnRemove1"></Button>
</StackPanel>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I have listbox that displays information about list of objects:
<ListBox Grid.Column="0" Height="152" Name="CustomersList" HorizontalAlignment="Stretch">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=Name, Mode=OneWay}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I would show more detailed information about selected item in another block, but I don't know (and can't find) how to bind selected item to those block data context. I guess it should be something like this:
<Grid Grid.Column="1" DataContext="{Binding Path=ItemSelected, UpdateSourceTrigger=PropertyChanged}" VerticalAlignment="Top">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="250"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Text="Id" VerticalAlignment="Center" />
<TextBox Grid.Row="0" Grid.Column="1" Text="{Binding Path=Id}" VerticalAlignment="Center"/>
<TextBlock Grid.Row="1" Grid.Column="0" Text="Name" VerticalAlignment="Center"/>
<TextBox Grid.Row="1" Grid.Column="1" Text="{Binding Path=Name}" VerticalAlignment="Center"/>
<StackPanel Grid.Row="2" Grid.ColumnSpan="2" Orientation="Horizontal" HorizontalAlignment="Center">
<Button Content="Add new" />
<Button Content="Store changes" />
</StackPanel>
</Grid>
But the problem is that data item to be binded to the grid is not specified anywhere and I don't know how to do that.
Any suggestion would be wellcome.
Thanks!
P.S. I've tried to specify CustomersList.ItemsSource as DataContext for the Grid - this didn't give any result.
You can bind to the SelectedItem property of the ListBox, one way is using ElementName.
<Grid DataContext="{Binding ElementName=CustomersList, Path=SelectedItem}"> </Grid>
I have this ListView and I'm using a DataTemplate (as you can see) for items.
How can i add column names to the ListView with this ItemTemplate definition?
I cannot use that GridViewColumn definition, because this ListView uses lazy data loading, so when there are too many rows, it fetches them on demand. GridViewColumn somehow does not function with this lazy loading.
<ListView Grid.Row="3">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid x:Name="grid" Background="Transparent" MinWidth="580" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="220" />
<ColumnDefinition Width="100" />
<ColumnDefinition Width="100" />
<ColumnDefinition Width="70"/>
<ColumnDefinition Width="80"/>
</Grid.ColumnDefinitions>
<TextBlock VerticalAlignment="Center" Grid.Column="0" Text="{Binding Path=Benutzer.Value.Code}"/>
<TextBlock VerticalAlignment="Center" Grid.Column="1" Text="{Binding Path=Nachname}"/>
<TextBlock VerticalAlignment="Center" Grid.Column="2" Text="{Binding Path=Vorname}"/>
<TextBlock VerticalAlignment="Center" Grid.Column="3">
<TextBlock.Text>
<Binding Path="GeburtDate" StringFormat="{}{0:d}"/>
</TextBlock.Text>
</TextBlock>
<Button VerticalAlignment="Center" Grid.Column="4" Style="{StaticResource StyleEditButton}" Content="Öffnen..." Tag="{Binding}" Click="OpenPersonButton_Click"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ListView>
I don't think there is any point in using a ListView if, as you say, you cannot use GridView (or any other view). I would exchange ListView for ItemsControl (or ListBox if you need a selectable item or any of the other things that ListBox offers).
If what you say is true, you could just use a stack panel to position a header row above your data rows:
<StackPanel>
<!-- Header -->
<StackPanel Orientation="Horizontal">
<TextBlock Width="220" TextAlignment="Center" Text="Code" />
<TextBlock Width="100" TextAlignment="Center" Text="Nachname" />
<TextBlock Width="100" TextAlignment="Center" Text="Vorname" />
<TextBlock Width="70" TextAlignment="Center" Text="GeburtDate" />
</StackPanel>
<!-- Data rows -->
<ItemsControl>
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" MinWidth="580">
<TextBlock Width="220" TextAlignment="Center" Text="{Binding Path=Benutzer.Value.Code}" />
<TextBlock Width="100" TextAlignment="Center" Text="{Binding Path=Nachname}" />
<TextBlock Width="100" TextAlignment="Center" Text="{Binding Path=Vorname}" />
<TextBlock Width="70" TextAlignment="Center" Text="{Binding Path=GeburtDate, StringFormat={0:d}}" />
<Button VerticalAlignment="Center" Grid.Column="4" Style="{StaticResource StyleEditButton}" Content="Öffnen..." Tag="{Binding}" Click="OpenPersonButton_Click"/>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
Hope that helps. You might also like to read about virtualizing panels. That might provide the kind of laziness you're talking about.
