Hi!

I have a WPF listbox and have updated the list item data template to have essentially a 3 column layout.

I would like:

|status color|name| buttons|

These are probably CSS terms but I want to float the status color and name to the left, which I've done, then I would like the buttons to be floated to the right, and always stay to the right even as the window gets wider.

I feel like I'm so close, the list item widths grow when the window gets wider, all I feel I have to do is tell the buttons to float right but can't figure out how. I've tried stack panels, a grid with a auto|*|auto column layout (With a stretch on the last column) and I've tried a dockpanel.

Here's my XAML:

    <Controls:MetroWindow x:Class="Appsecute.Views.MainView2"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:AppsecuteControls="clr-namespace:Appsecute.Controls"

    Re: How to right align some elements of WPF ListItem?

    Hi!

    The problem is at the first level below DataTemplate, here:

    <StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">

    By its nature a StackPanel will align items to the left, so it's not a layout that's well suited to what you want to do. Instead try using a Grid with two columns, giving the left column Width=* and the right Width=Auto.

    <ListBox HorizontalContentAlignment="Stretch">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*" />
                        <ColumnDefinition Width="Auto" />
                    </Grid.ColumnDefinitions>
                    <StackPanel Grid.Column="0" Orientation="Vertical">
                        ...
                    </StackPanel>
                    <DockPanel Grid.Column="1" VerticalAlignment="Center">
                        ...
                    </DockPanel>
                </Grid>
            <DataTemplate>
        </ListBox.ItemTemplate>
    <ListBox>
