CodePudding user response：

You can do something like this:

    <ListBox ItemsSource="{Binding YourList}">
        <ListBox.ItemsPanel>
            <ItemsPanelTemplate>
                <UniformGrid Columns="3"/>
            </ItemsPanelTemplate>
        </ListBox.ItemsPanel>
    </ListBox>

Then even when you enlarge the window you will be left with 3 items in each column
