Question

I can’t get my WPF layout working. I want the ListBox to stretch vertically by anchoring to the bottom of the window. It currently just sizes to the height of the controls in the StackPanel (the Add and Remove buttons), and resizes to accomodate items that are added. In WinForms I would just set ListView.Anchor to Top|Left|Bottom|Right but I shouldn’t live in the past. I’ve tried a number of things like putting it in a DockPanel, wrapping everything in Canvas, etc., but nothing seems to be affected.

Here is my XAML:

<Window x:Class="FileDropAdmin.ViewsTestListView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
        xmlns:shared="http://schemas.markpad.net/winfx/xaml/shared"
        Title="ViewsTestListView" Height="300" Width="416">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>

        <TextBlock TextWrapping="Wrap" VerticalAlignment="Top" Text="Things:" />
        <Grid Grid.Row="1">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="4*"/>
                <ColumnDefinition Width="1*"/>
            </Grid.ColumnDefinitions>   

            <ListBox x:Name="Things" DisplayMemberPath="ThingName" SelectedItem="CurrentThing" Grid.Column="0"/>
            <StackPanel Margin="5 0 0 0" VerticalAlignment="Top" Grid.Column="1">
                <Button x:Name="AddThing" Content="Add" Margin="0 0 0 0" VerticalAlignment="Top"/>
                <Button x:Name="RemoveThing" Content="Remove" Margin="0 5 0 0" VerticalAlignment="Top"/>
            </StackPanel>
        </Grid>
    </Grid>
</Window>

Set your second row to Height=”*” and It should take all the space of the window if it’s what you need
