Fuse 0.25.1

```auto
<App>
   <Panel ux:Name="thing" Height="Auto" />
</App>

```

`Auto` doesn’t work.  
`<Change thing.Height="Auto" />` doesn’t work either

Hi!

`Width` and `Height` are of type [**`Size`**](https://www.fusetools.com/docs/uno/ux/size). They cannot be set to `Auto`, however they default to `Auto` when not set

From `Size` docs

> If not specifying a value, many properties will default to Size.Auto, where the size will be computed automatically based on context.

Hey,  
Thanks for the answer, is there a way to manually set it to Auto after changing the height to a set value?

Cheers

If you need to change anything to different values interchangeably. Use `Change` in a `Trigger` instead of `Set`:

```auto
<Panel ux:Name="panel" />
<Switch ux:Name="switch" />
<WhileTrue Value="{Property switch.Value}">
  <Change Target="panel.Height" Value="50" />
</WhileTrue>

```

When the `switch` is false it’ll be `auto` again.
