Question

I have two panels, only one should be visible at the same time. I change between them by clicking a button, one on each panel.

Is there a nice way to do this in xaml without codebehind or viewmodel?

The suggestion with using a tabcontrol is good. I found some code which styles a TabControl to only show the TabItem content

<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <Grid>
    <TabControl BorderThickness="0" Padding="0">
      <TabControl.Resources>
        <Style TargetType="TabItem">
          <Setter Property="Template">
            <Setter.Value>
              <ControlTemplate TargetType="TabItem">
              </ControlTemplate>
            </Setter.Value>
          </Setter>
        </Style>
      </TabControl.Resources>
      <TabItem Header="Not shown">
        <Grid Background="Red"/>
      </TabItem>
      <TabItem>
        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center">Tab 2

        </TextBlock>
      </TabItem>
    </TabControl>
  </Grid>
