WrapPanel in ListBox doesn't wrap but shows scrollbar

[PeterVD-Lansweeper]

Hi,

I'm trying to use a WrapPanel as the ItemsPanel in a ListBox, but I don't get the behavior I want. (I'm using Avalonia v0.10.0)
The WrapPanel doesn't wrap, but puts all items on one line and shows a horizontal scrollbar.

This is the XAML:

<ListBox Items="{Binding CodeOwners, Mode=OneWay}" >
	<ListBox.ItemsPanel>
		<ItemsPanelTemplate>
			<WrapPanel />
		</ItemsPanelTemplate>
	</ListBox.ItemsPanel>
	<ListBox.ItemTemplate>
		<DataTemplate>
			<StackPanel Orientation="Horizontal">
				<CheckBox IsChecked="{Binding IsSelected, Mode=TwoWay}"></CheckBox>
				<TextBlock Text="{Binding Description, Mode=OneWay}" Margin="5,0,0,0" ></TextBlock>
			</StackPanel>
		</DataTemplate>
	</ListBox.ItemTemplate>
</ListBox>

What am I doing wrong here?
I tried binding the WrapPanel's Width to the width of the ListBox, but that didn't have any effect.

When I give the ListBox a fixed size, the wrapping works fine.
But using a Grid-Layout and let it take al the space that is available (in a ColumnDefinition Width="*") and the WrapPanel's size is messed up.

It works for me: ListBoxBinding.zip.

Probably some ListBox parent is measuring with infinite width (e.g. a StackPanel, ScrollViewer,...).

Try to add this

ScrollViewer.HorizontalScrollBarVisibility="Disabled"

i.e.

<ListBox Items="{Binding CodeOwners, Mode=OneWay}" ScrollViewer.HorizontalScrollBarVisibility="Disabled">

That did the trick. Thanks. :-)
