I have the following situation:
Inside my main page, I have an ItemsControl and the ItemsPanelTemplate is set to a WrapPanel
<ItemsControl Grid.Row="1" ItemsSource="{Binding StepItems}" x:Name="ItemsControl" Visibility="{Binding ActualView, Converter={StaticResource ActualViewConverter}, ConverterParameter=TableView}" Width="{Binding TableWidth}" Margin="0,5,0,0">
<ItemsControl.ItemContainerStyle>
<Style>
<Setter Property="FrameworkElement.Margin" Value="0,5,10,5"/>
</Style>
</ItemsControl.ItemContainerStyle>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel x:Name="itemsWrapPanel" Orientation="Horizontal" HorizontalAlignment="Left" VerticalAlignment="Top"></WrapPanel>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
The bound List "StepITems" contains several controls which itself also represents an ItemsControl as WrapPanel
<ItemsControl ItemsSource="{Binding Rows, ElementName=Root}" x:Name="ItemsControl">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel x:Name="itemsWrapPanel" Orientation="Horizontal" HorizontalAlignment="Stretch" VerticalAlignment="Center"></WrapPanel>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<hmiControl:ScrewPointControl Margin="0,0,10,0"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
The Problem is now, that if the next list has not enough space inside the actual row, it starts in a new row, instead of wrapping.
Three ItemsControls with space between each other
Is there a way to manage that the second ItemsControl starts directly after the first and then the second wraps if there is no space anymore?
Greetings,

I am trying to create a custom MessageBox with variable number of buttons, this number being equal to the Count of ItemsSource. The buttons are to be placed in a UniformGrid. ItemsSource of ButtonView is assigned to ObservableCollection Buttons. Buttons.Count is not recognized by the code. How could I correctly assign UniformGrid Columns value?
<ItemsControl Grid.Row="2" x:Name="ButtonView">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="{Binding Buttons.Count}">
</UniformGrid>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate DataType="Button">
<Button Margin="2" Content="{Binding Content}"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
Set the Rows property instead of Columns:
<ItemsPanelTemplate>
<UniformGrid Rows="1"/>
</ItemsPanelTemplate>
I am new to WPF/Xaml and searched for this issue I am facing but found it tough. Requesting some help on this.
I need to display usercontrols (DATABOUND) (horizontally) inside a panel/listview so that they wrap when the width of listview/panel is met, with a vertical scroll bar autoshown (as in figure).
so far I have this code.
<ListView Grid.Row="3"
ItemsSource="{Binding Controls}"
VerticalAlignment="Bottom" Background="{x:Null}" BorderBrush="{x:Null}"
>
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" Margin="0,0,0,10"></StackPanel>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="VerticalContentAlignment" Value="Bottom"/>
<Setter Property="Focusable" Value="False" />
</Style>
</ListView.ItemContainerStyle>
<!--<ListView.ItemTemplate>
<DataTemplate>
<ContentControl Content="{Binding}" VerticalContentAlignment="Bottom"/>
</DataTemplate>
</ListView.ItemTemplate>-->
</ListView>
I have even tried the below code. Yes, it wraps but no scrollbar appears!
<ItemsControl Grid.Row="3"
Width="100" Height="200"
ItemsSource="{Binding Controls}"
VerticalAlignment="Bottom" Background="{x:Null}" BorderBrush="{x:Null}"
>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Horizontal" Margin="0,0,0,10"></WrapPanel>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
Note: I am okay with any control that makes this happens. Not necessarily be a listview.
To wrap items you need to set ItemsPanel to WrapPanel, like in second example, but you may need to disable horizontal scrolling on ListView:
<ListView ScrollViewer.HorizontalScrollBarVisibility="Disabled" .../>
also, if you want to use ItemsControl then ScrollViewer is not part of default Template, like for ListView, so you'll need to wrap in in ScrollViewer
<ScrollViewer Grid.Row="3">
<ItemsControl ...>
<!-- .... -->
</ItemsControl>
</ScrollViewer>
and don't forget to move Grid.Row="3" from ItemsControl definition to ScrollViewer
You were close :-)
Put your listview with a view panel that is a wrapanel inside your scrollviewer.
<ScrollViewer>
<ItemsSource="{Binding Controls}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel></WrapPanel>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</ScrollViewer>
You are using Wrap panel so you need to specify the width it supposed to take... since wrappanel is inside a items host control wrap panel itself cannot calculate the width.It will try to take all the width with respective to Orientation (in your case its horizontal)
Here is the sample code with list box as items host... in this code i have binded the wrappanel width to the actual width of the list box so that it will never take more width than the list box and also i disabled the horizontal scrolling which you don't need for horizontal orientation and vertical wrapping
Note: Make sure to change item template before using following code and it will work with all items hosts like ListView, ItemsControl...
<ListBox Width="500" Height="500" Name="listbox" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Horizontal" Width="{Binding ActualWidth,ElementName=listbox}"></WrapPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Grid Height="100" Width="100">
<TextBlock Text="{Binding}" VerticalAlignment="Center" HorizontalAlignment="Center"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
For ItemsControl
<ItemsControl Grid.Row="3"
Width="100" Height="200"
ItemsSource="{Binding Controls}"
VerticalAlignment="Bottom" Background="{x:Null}" BorderBrush="{x:Null}"
Name="listbox"
>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel IsItemsHost="True" Orientation="Horizontal" Width="{Binding ActualWidth,ElementName=listbox}"></WrapPanel>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.Template>
<ControlTemplate>
<ScrollViewer x:Name="ScrollViewer" Padding="{TemplateBinding Padding}">
<ItemsPresenter />
</ScrollViewer>
</ControlTemplate>
</ItemsControl.Template>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Height="30" Width="30">
<TextBlock Text="{Binding}" VerticalAlignment="Center" HorizontalAlignment="Center"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
I have a listbox (with normal vertical orientation), each element of which is a listbox with horizontal orientation.
I want to have a ScrollBar inside of internal listbox. So, my problem is how to set width of internal listbox according to real current width of external.
My current code is:
<Window.Resources>
<HierarchicalDataTemplate x:Key="ItemTemplateSchedule">
<ListBox>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBoxItem>My-Very-Long-Item-Nimber-1___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Nimber-2___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Nimber-3___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Nimber-4___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Nimber-5___</ListBoxItem>
</ListBox>
</HierarchicalDataTemplate>
</Window.Resources>
<Grid>
<ListBox ItemTemplate="{StaticResource ItemTemplateSchedule}" >
>
</ListBox>
</Grid>

Ok, answer to my question is setting of width for internal listbox, thanks to #sa_ddam213:
Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=ListBox}, Path=ActualWidth}"
Now I want add some new control in each row of external listbox:
<HierarchicalDataTemplate x:Key="ItemTemplateSchedule">
<StackPanel Orientation="Horizontal" Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=ListBox}, Path=ActualWidth}">
<TextBlock Text="This is Text in a TextBlock"/>
<ListBox >
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBoxItem>My-Very-Long-Item-Number-1___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Number-2___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Number-3___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Number-4___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Number-5___</ListBoxItem>
</ListBox>
</StackPanel>
</HierarchicalDataTemplate>
And it doesn't work now! Is it possible to solve this problem? Current screenshot:
You can use a FindAncestor to bind to the parent ListBox ActualWidth
Example:
<Window.Resources>
<HierarchicalDataTemplate x:Key="ItemTemplateSchedule">
<ListBox Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=ListBox}, Path=ActualWidth}" >
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBoxItem>My-Very-Long-Item-Nimber-1___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Nimber-2___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Nimber-3___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Nimber-4___</ListBoxItem>
<ListBoxItem>My-Very-Long-Item-Nimber-5___</ListBoxItem>
</ListBox>
</HierarchicalDataTemplate>
</Window.Resources>
Result:
I have WrapPanel where I want the control inside of it to go horizontally and centered, but when I have a listbox or a ItemsControl those elements just go downwards.
<toolkit:WrapPanel>
<ItemsControl x:Name="AnswerListBox" ItemsSource="{Binding Answers}" ScrollViewer.VerticalScrollBarVisibility="Disabled" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<!-- those don't wrap horizontally and go downwards -->
<local:spriteToggleButton Text="{Binding text}" Selected="{Binding selected}" Sprites="{Binding Path=DataContext.UISprites, ElementName=questionField}" IsChecked="{Binding selected, Mode=TwoWay}" GroupName="{Binding Path=DataContext.QuestionTitle, ElementName=questionField}" ClickMode="Press" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</toolkit:WrapPanel>
I came across some similar issues and found out about ItemsPanel, so I tried that but it wrap but only to Content and didn't display the rest of the control inside of it.
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
I take it that ItemsPanel is telling the ItemsControl which control to wrap it with but then it seems to ignore the rest of my datatemplate.
Joseph,
Slightly shooting in the dark here; but this is how I have used the WrapPanel (not through the ItemControl).
<ListBox>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel Width="700" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
....
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Essentially the Listbox's ItemsPanel tells it to use the WrapPanel and then you could have anything you need in the DataTemplate. Note that the width is important as it tells the WrapPanel where to start wrapping.
Does this help?
I'm trying to write a WPF application for displaying images from a selection.
I want to display all of the available images in a banner along the top of the window, and display the main selected image in the main window for further processing.
If I wanted the list on the Left of the window, displaying the images vertically, I can do this quite elegantly using databinding.
<ListBox
Name="m_listBox"
IsSynchronizedWithCurrentItem="True"
ItemsSource="{Binding}"
>
<ListBox.ItemTemplate>
<DataTemplate>
<Image Source="{Binding}" Width="60" Stretch="Uniform" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Is there a straightforward way I can make this horizontal instead of vertical?
The main requirements of a solution is:
The items are populated using databinding
The selected item is changed simply by the user clicking it.
WrapPanel
<ListBox ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel IsItemsHost="True" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBoxItem>listbox item 1</ListBoxItem>
<ListBoxItem>listbox item 2</ListBoxItem>
<ListBoxItem>listbox item 3</ListBoxItem>
<ListBoxItem>listbox item 4</ListBoxItem>
<ListBoxItem>listbox item 5</ListBoxItem>
</ListBox>
WPF Tutorial
The default ItemsPanel for the ListBox control is a VirtualizingStackPanel, so if you want the normal, default experience for the control but just have it laid out horizontally, you should specify this (and change the orientation).
Example:
<ListBox>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<VirtualizingStackPanel IsItemsHost="True" Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
Here is example of StackPanel.
Horizontal Breadcrumb with Mvvm binding
<ItemsControl
x:Name="tStack"
Grid.Row="1"
Grid.Column="0"
Height="40"
Background="Red"
ItemsSource="{Binding BreadCrumbs}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button
Margin="5"
CommandParameter="{Binding .}"
Command="{Binding BreadcrumbClickCommand, RelativeSource={RelativeSource AncestorType=ItemsControl}, Path=DataContext.BreadcrumbClickCommand}"
Content="{Binding Name}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
