WPF Listview Display - wpf

Question

I'm trying to display a Listview items through RectangleBox (Which I managed to do using ControlTemplate)
My problem is the how the RectangleBox are being organised on the window.
I'd like to display as many as I can on one line (Depending on the windows' width) and when one line is filled, go start a new one and so on.
The organisation would be updated depending on the window's width after each resize:
This might give a better idea of what I want, you see each RectangleBox (Labelled 1,2...) organisation on the window changing depending on its width.
Here is my current code in my MainWindow xaml:
<ListView Name="PlayerList" ItemsSource="{Binding Players}">
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid/>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
</ListView>
Having the following Style applied:
<Style TargetType="ListViewItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListViewItem}">
<GroupBox Header="{Binding Name}" Width="250" Height="125" Name="Disp" HorizontalAlignment="Left">
<GroupBox.HeaderTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding}" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="5,0,0,0" TextAlignment="Right"></TextBlock>
</StackPanel>
</DataTemplate>
</GroupBox.HeaderTemplate>
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Char}"/>
<TextBlock Text="{Binding Item}"/>
</StackPanel>
</GroupBox>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
But so far, the UniformGrid was just a failled attempt, I've been looking around but couldn't really find a solution. Hopefully it was just me being dumb and missing something obvious D:
Thanks for the help.

Thanks for few comments.
WrapPanel was indeed the right way, just didn't think of it :P
I just needed to add the following property:
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
To my listview in order to avoid all the items to stack on one line.
