I am trying to display buttons dynamically on the screen in a wrap panel so that they are laid our nicely without any scrollbars. I have the markup as below, but the scrollbars appear for some reason. how do we make the scrollbar not appear and the buttons laid out without any scrollbars.
<ListBox x:Name="ItemsListBox" >
<ListBox.ItemTemplate>
<DataTemplate>
<ToggleButton Content="{Binding Name}" Click="Click" MinWidth="120" MinHeight="70" FontWeight="Bold" FontSize="18"/>
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel></WrapPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
What control is your ListBox inside? Most often the problem you descrive is caused by the parent control allowing the ListBox to grow.
You can prove whether this is the problem by setting an explicit Width="200" on your ListBox and testing what happens. If it wraps, then the problem is the ListBox's parent.
Add
ScrollViewer.VerticalScrollBarVisibility="Hidden"
ScrollViewer.HorizontalScrollBarVisibility="Hidden"
to you containers.
This does it what I was trying to achieve.
<ItemsControl x:Name="ListBox" Grid.Row="5" Grid.ColumnSpan="2">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Vertical"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<ToggleButton Content="{Binding Name}" MinWidth="120" MinHeight="50" FontWeight="Bold" FontSize="16" Margin="5"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>

I have encountered a problem - i have created a project where i bind my code to xaml by using a bind to the listbox. However, it has created some problems in my future code - i want to add button to my form, but i encounter some errors.
'Items collection must be empty before using ItemsSource.'
This Error occurs when i try to bind something outside of my bindable Listbox.
The property "VisualTree" can only be set once.
This Error occurs when i try to add button underneath the Listbox.
Can someone guide me on how can i fix this?
My code:
<ListBox x:Name="ItemsControl1">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="5">
</UniformGrid>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" BorderThickness="2" Width="Auto" Height="Auto">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Number}"/>
<Image Source="{Binding Source}" Margin="0,0,5,0"/>
</StackPanel>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
The desirable result would be a button under the listbox.
You should add your button below ListBox declaration.
Exceptions you are facing are thrown because visual tree is populated via binding and you cannot alter it manually anymore.
You will need to put all this stuff inside of some layout container (Grid, StackPanel, etc.), since you cannot set Window's/UserControl's Content property twice:
<StackPanel>
<ListBox x:Name="ItemsControl1">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="5">
</UniformGrid>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" BorderThickness="2" Width="Auto" Height="Auto">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Number}"/>
<Image Source="{Binding Source}" Margin="0,0,5,0"/>
</StackPanel>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<Button/>
</StackPanel>
I want my custom build ListBox to display the items on the next line if their size exceeds the available width of their parent control.
Following is my XAML for this purpose.
<materialDesign:Card>
<StackPanel>
<TextBlock FontWeight="DemiBold" FontSize="30">Schedule</TextBlock>
<ListBox ItemsSource="{Binding Schedule, Source={StaticResource dc}}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<ListBoxItem>
<StackPanel Orientation="Horizontal">
<StackPanel Orientation="Horizontal">
<TextBlock>Day:</TextBlock>
<TextBlock Text="{Binding Key, Mode=OneWay}" />
</StackPanel>
<materialDesign:TimePicker materialDesign:HintAssist.Hint="Time In" SelectedTime="{Binding Value.TimeIn}" />
<materialDesign:TimePicker materialDesign:HintAssist.Hint="Time Out" SelectedTime="{Binding Value.TimeOut}" />
</StackPanel>
</ListBoxItem>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</materialDesign:Card>
Following is the Output for the above XAML
You should use a WrapPanel instead of a StackPanel, then.
As H.B. said, the ItemPanel control you should use is a WrapPanel that let you achieve what you want (when there isn't enough space for your control, it creates a new line).
Here it is an example:
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
I have a horizontal Listbox bound to an enum including a EnumToImageSource Converter working and need the Listbox/view to get a selectedItem.
I need the images in the Listbox to scale down their width to be all visible side by side without a horizontal scrollbar appearing even when resizing the window.
The Solutions in this question only work for normal vertical Listviews. Can this even be done what i'm trying to archive?
<ListBox HorizontalContentAlignment="Stretch"
ScrollViewer.HorizontalScrollBarVisibility="Hidden"
ItemsSource="{Binding Source={StaticResource shoeValuesProvider}}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Image Source="{Binding Converter={StaticResource ShoeToImageConverter}}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Thanks to Sinatr's comment i found out the solution which indeed uses a UniformGrid with one Row defined and setting the width to the ancestor ScrollContentPresenter as noted here:
<StackPanel x:Name="ReferenceStackPanel">
<ListBox HorizontalContentAlignment="Stretch"
ScrollViewer.HorizontalScrollBarVisibility="Hidden"
SelectedItem="{Binding ShoeModel}"
ItemsSource="{Binding Source={StaticResource shoeValuesProvider}}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Margin="0" Rows="1" Width="{Binding ActualWidth,RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ScrollContentPresenter}}}"></UniformGrid>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Image Source="{Binding Converter={StaticResource ShoeToImageConverter}}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
My WPF Application is generating dynamic Buttons. I want to show these Button Horizontally. I wrote Code for this. Code is working fine but rather than showing button in Horizontal Direction, it is showing all Buttons in Vertical Direction! Where i also set Orientation of StackPanel!
Can anyone solve my Problem?
My Code is:
<Grid>
<dxlc:ScrollBox>
<ItemsControl x:Name="Buttonslist">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Button Content="{Binding Text}" Tag="{Binding Text}" x:Name="New" Margin="5,0,5,0" Click="New_Click" />
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</dxlc:ScrollBox>
</Grid>
You're actually creating a StackPanel for each item/Button. To get just one for all the items you need to set the ItemsPanel of the control to a StackPanel.
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Content="{Binding Text}" Tag="{Binding Text}" x:Name="New" Margin="5,0,5,0" Click="New_Click" />
</DataTemplate>
</ItemsControl.ItemTemplate>
I'm trying to align my WrapPanel to have the same spacing size, although I can't figure out how. Here's an example of what I want,
XAML Code:
<ListBox Grid.Row="1" ItemsSource="{Binding HolidayGenerator}" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<CheckBox Content="{Binding Name}" IsChecked="{Binding IsSelected, Mode=TwoWay}" HorizontalAlignment="Right" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Any help is greatly apperciated.
I can't be sure that this will work, but I'm thinking that you may be able to coerce the vertical alignment of each column by setting the ItemWidth property on the WrapPanel (using a value that is appropriate based on the column width that you want it to render with):
<ItemsPanelTemplate>
<toolkit:WrapPanel Orientation="Horizontal" ItemWidth="25" />
</ItemsPanelTemplate>
