AdaptiveTrigger can help you create a dynamic responsive UI based on the height or width of the device or screen. It has two important PROPERTIES: MinWindowWidth and MinWindowHeight.

XAML

<Page>

<Grid>

<VisualStateManager.VisualStateGroups>

<VisualStateGroup>

<VisualState>

<VisualState.StateTriggers>

<!--VisualState to be triggered when window width is >=750 and windows height is >=900 effective pixels.-->

<AdaptiveTrigger MinWindowWidth="750" MinWindowHeight="900" />

</VisualState.StateTriggers>

<VisualState.Setters>

<Setter Target="myPanel.Orientation" Value="Horizontal" />

</VisualState.Setters>

</VisualState>

</VisualStateGroup>

</VisualStateManager.VisualStateGroups>

<StackPanel x:Name="myPanel" Orientation="Vertical">

<TextBlock Text="text block 1. "/>

<TextBlock Text="text block 2. "/>

<TextBlock Text="text block 3. " />

</StackPanel>

</Grid>

</Page>

From above code, StateTriggers property with an AdaptiveTrigger to create a DECLARATIVE rule in XAML MARKUP based on window size. By default, the StackPanel orientation is Vertical. When the window width is >= 750 and the windows height is >=900 effective pixels, the VisualState change is triggered, and the StackPanel orientation is changed to Horizontal.
