Tip

For more info, design guidance, and code examples, see Layout panels.

The WinUI 3 Gallery app includes interactive examples of most WinUI 3 controls, features, and functionality. Get the app from the Microsoft Store or get the source code on GitHub.

Remarks

RelativePanel is a layout container that is useful for creating UI that do not have a clear linear pattern; that is, layouts that are not fundamentally stacked, wrapped, or tabular, where you might naturally use a StackPanel or Grid.

If your UI consists of multiple nested panels, RelativePanel is a good option to consider.

Here's an example of a UI using a RelativePanel for its layout:

Relative panel control
<RelativePanel BorderBrush="Gray" BorderThickness="10">
    <Rectangle x:Name="RedRect" Fill="Red" MinHeight="100" MinWidth="100"/>
    <Rectangle x:Name="BlueRect" Fill="Blue" MinHeight="100" MinWidth="100" 
               RelativePanel.RightOf="RedRect"/>
    <!-- Width is not set on the green and yellow rectangles.
         It's determined by the RelativePanel properties. -->
    <Rectangle x:Name="GreenRect" Fill="Green" MinHeight="100" Margin="0,5,0,0" 
               RelativePanel.Below="RedRect" 
               RelativePanel.AlignLeftWith="RedRect" 
               RelativePanel.AlignRightWith="BlueRect"/>
    <Rectangle Fill="Yellow" MinHeight="100" 
               RelativePanel.Below="GreenRect" 
               RelativePanel.AlignLeftWith="BlueRect" 
               RelativePanel.AlignRightWithPanel="True"/>
</RelativePanel>

RelativePanel, used in conjunction with AdaptiveTrigger s, can be a powerful tool to create responsive UI that scales well across different screen sizes. For more examples, see the XAML Responsive Techniques sample.

Default position

By default, any unconstrained element declared as a child of the RelativePanel is given the entire available space and positioned at the (0, 0) coordinates (upper left corner) of the panel. So, if you are positioning a second element relative to an unconstrained element, keep in mind that the second element might get pushed out of the panel.

In this example, RectA doesn't have any constraints, so it's positioned at (0,0). RectB is not shown on the screen because it is declared to be Above RectA and is therefore pushed out of the panel.

<RelativePanel>
    <Rectangle Name="RectA" Fill="Red" Height="40" Width="40"/>
    <Rectangle Name="RectB" Fill="Blue" Height="40" Width="40"
               RelativePanel.Above="RectA"/>
</RelativePanel>

Circular dependency

A circular dependency occurs when two elements inside a RelativePanel declare relationships with each other in any direction. For example, this XAML results in a design-time exception, "RelativePanel error: Circular dependency detected. Layout could not complete."

<RelativePanel>
    <Rectangle Name="RectA" Fill="Red" Height="40" Width="40"
               RelativePanel.Above="RectB"/>
    <Rectangle Name="RectB" Fill="Blue" Height="40" Width="40"
               RelativePanel.Below="RectA"/>
</RelativePanel>

Conflicting relationships

If you set multiple relationships that target the same edge of an element, you might have conflicting relationships in your layout as a result. When this happens, the relationships are applied in the following order of priority:

The panel-center alignment properties (AlignVerticalCenterWith, AlignHorizontalCenterWithPanel, ...) are typically used independently of other constraints and are applied if there is no conflict.

The HorizontalAlignment and VerticalAlignment properties on UI elements are applied after relationship properties are evaluated and applied. These properties control the placement of the element within the available size for the element, if the desired size is smaller than the available size.

Border properties

RelativePanel defines border properties that let you draw a border around the RelativePanel without using an additional Border element. The properties are RelativePanel.BorderBrush, RelativePanel.BorderThickness, RelativePanel.CornerRadius, and RelativePanel.Padding.

<RelativePanel BorderBrush="Red" BorderThickness="2" CornerRadius="10" Padding="12">
    <TextBox x:Name="textBox1" RelativePanel.AlignLeftWithPanel="True"/>
    <Button Content="Submit" RelativePanel.Below="textBox1"/>
</RelativePanel>

XAML attached properties

RelativePanel is the host service class for several XAML attached properties.

In order to support XAML processor access to the attached properties, and also to expose equivalent get and set operations to code, each XAML attached property has a pair of Get and Set accessor methods. Another way to get or set the value in code is to use the dependency property system, calling either GetValue or SetValue and passing the identifier field as the dependency property identifier.
