[SOLVED] Set list items to grow to the width of the containing ListView

Set list items to grow to the width of the containing ListView - WPF

I would like the items of my ListView to grow to take up the entire width of the available space within the ListView.

Currently, I have the item's width set like this (the ListView is named listView):

Width="{Binding ActualWidth, ElementName=listView, Mode=OneWay}"

The items will take up the width of the ListView. However, the vertical scroll bar is not taken into account. If the scroll bar is present, it is drawn on top of the right edge of the items.

Is it possible to fix this?

Solution

I solved this by referencing the ItemsPresenter directly. To do this, I needed to define a template for the Viewbox and name the ItemsPresenter.

The template looks like this:

<ListView.Template>
    <ControlTemplate TargetType="{x:Type ListView}">
        <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="1" SnapsToDevicePixels="true">
            <ScrollViewer Focusable="false" Padding="{TemplateBinding Padding}">
                <ItemsPresenter x:Name="MLVItemsPresenter" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
            </ScrollViewer>
        </Border>
       <--SNIP-->
    </ControlTemplate>
</ListView.Template>

And the width binding looks like this:

Width="{Binding ActualWidth, ElementName=MLVItemsPresenter, Mode=OneWay}"
