Can't get VariableSizedWrapGrid to wrap - xaml

Question

I'm having issues getting the VariableSizedWrapGrid to wrap horizontally. All I can seem to get are my elements stacked vertically in a single column. I'm not sure what I'm missing.
Ideally I would like to have 3 columns of input fields. The number of fields changes depending on the table selected so they need to just, you know, wrap.
<ScrollViewer
Grid.Column="0"
Grid.ColumnSpan="2"
Grid.Row="1"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch">
<VariableSizedWrapGrid
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Orientation="Horizontal">
<ItemsControl
ItemsSource="{x:Bind ViewModel.CurrentRow.Values}">
<ItemsControl.ItemTemplate>
<DataTemplate x:DataType="models:RowValue">
<Grid Width="Auto">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock
Text="{x:Bind key.ColumnValidation.column_label}"
Margin="0"
Padding="0"
Grid.Column="0">
</TextBlock>
<TextBox
Grid.Column="1"
Visibility="{x:Bind vm:Converters.IsTextBoxField(key.ColumnValidation.data_type)}"
Text="{x:Bind value}">
</TextBox>
<RichTextBlock
Visibility="{x:Bind vm:Converters.IsHyperlinkField(key.ColumnValidation.data_type)}">
<Paragraph>
<Span>
<Hyperlink />
</Span>
</Paragraph>
</RichTextBlock>
<DatePicker
Visibility="{x:Bind vm:Converters.IsDateField(key.ColumnValidation.data_type)}">
</DatePicker>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</VariableSizedWrapGrid>
</ScrollViewer>

Turns out I didn't fully understand how ItemsControl works. Managed to get it working like so:
<ScrollViewer
Grid.Column="0"
Grid.ColumnSpan="2"
Grid.Row="1"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch">
<ItemsControl
Height="Auto"
Width="Auto"
ItemsSource="{x:Bind EditRow.Values}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<VariableSizedWrapGrid
Orientation="Horizontal"
MaximumRowsOrColumns="4"
HorizontalAlignment="Stretch"
VerticalAlignment="Top"
ItemWidth="200"
ItemHeight="75">
</VariableSizedWrapGrid>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate x:DataType="models:RowValue">
<Grid
HorizontalAlignment="Stretch"
VerticalAlignment="Top"
Width="190"
Margin="5">
<TextBox
Header="{x:Bind key.ColumnValidation.column_label}"
Visibility="{x:Bind vm:Converters.IsTextBoxField(key.ColumnValidation.data_type)}"
Text="{x:Bind value, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
</TextBox>
<TextBox
Header="{x:Bind key.ColumnValidation.column_label}"
Visibility="{x:Bind vm:Converters.IsHyperlinkField(key.ColumnValidation.data_type)}"
Text="{x:Bind value, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
</TextBox>
<!-- todo: create converter for fusion date format -->
<Viewbox VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<DatePicker
Header="{x:Bind key.ColumnValidation.column_label}"
Visibility="{x:Bind vm:Converters.IsDateField(key.ColumnValidation.data_type)}">
</DatePicker>
</Viewbox>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</ScrollViewer>
