Question

I have a horizontal ListView which I would like to ensure that there is some padding between the items (in my case I have Grid inside of the item template), but I don’t want there to be any extra padding for the last grid

I want there to be padding where the red line is.

EDIT

H.B.’s suggestion was really helpful, here is the style that I added to get a 5px margin between grids…

<ListView.ItemContainerStyle>
    <Style TargetType="ListViewItem">
        <Setter Property="Margin" Value="5 0 0 0" />
        <Style.Triggers>
            <DataTrigger Binding="{Binding RelativeSource={RelativeSource PreviousData}}" Value="{x:Null}">
                <Setter Property="Margin" Value="0" />
            </DataTrigger>
        </Style.Triggers>
    </Style>
</ListView.ItemContainerStyle>

Answer 1

You can set a Padding in the ItemContainerStyle of the ListView. You can use a DataTrigger on RelativeSource PreviousData being null to make it conditional.

Alternatively you could create a new Panel which has a concept of spacing.
