This example creates a WPF Flow Layout Control. The form layout has four groups. Each group contains a TextBlock control.

WPF Flow Layout Control - Arrange Items Vertically and Enable Maximize Option

Enable Maximize Option

Use the FlowLayoutControl.MaximizedElement property to maximize the specified group (in this example this is the first group):

XAML
<lc:FlowLayoutControl Orientation="Vertical" Background="#FFFAFAFA" BreakFlowToFit="True"  
            MaximizedElementPosition="Right" MaximizedElement="{Binding ElementName=groupBox1}">  
    <lc:GroupBox x:Name="groupBox1" Header="Group 1" Style="{StaticResource  myGroupBoxStyle}">  
        <TextBlock  TextWrapping="Wrap" Text="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed molestie porttitor congue..."/>  
    </lc:GroupBox>  
  ...  
</lc:FlowLayoutControl>
