How to customize ColumnSizer based on orientation in .NET MAUI DataGrid (SfDataGrid)?

The .NET MAUI DataGrid allows you to customize the SfDataGrid.ColumnWidthMode based on device orientation using the SfDataGrid.SizeChanged event. This enables the view to automatically refresh according to the ColumnWidthMode when the orientation changes.

XAML:

<syncfusion:SfDataGrid  ItemsSource="{Binding Employees}"
                          AutoGenerateColumnsMode="None">
  <syncfusion:SfDataGrid.Columns>
      <syncfusion:DataGridTextColumn MappingName="EmployeeID"
                                     HeaderText="Employee ID" />
      <syncfusion:DataGridTextColumn MappingName="Name"
                                     HeaderText="Name" />
      <syncfusion:DataGridTextColumn MappingName="IDNumber"
                                     HeaderText="ID Number" />
  </syncfusion:SfDataGrid.Columns>

  <syncfusion:SfDataGrid.Behaviors>
      <behaviors:DataGridBehavior />
  </syncfusion:SfDataGrid.Behaviors>

</syncfusion:SfDataGrid>

behavior:

protected override void OnAttachedTo(SfDataGrid dataGrid)
{
   dataGrid.SizeChanged += ScrollOwner_SizeChanged;
   base.OnAttachedTo(dataGrid);
}        

protected override void OnDetachingFrom(SfDataGrid dataGrid)
{
   dataGrid.SizeChanged -= ScrollOwner_SizeChanged;
   base.OnDetachingFrom(dataGrid);
}
private void ScrollOwner_SizeChanged(object? sender, EventArgs e)
{
   SfDataGrid dataGrid = (SfDataGrid)sender;

   if (dataGrid.Width > dataGrid.Height)
       dataGrid.ColumnWidthMode = ColumnWidthMode.Fill;
   else
       dataGrid.ColumnWidthMode = ColumnWidthMode.Auto;
}
