How to display each row with different columns in Xamarin.Forms ListView (SfListView)

Platform: Xamarin.Forms |
Control: SfListView |
Published Date: March 18, 2020 |
Last Revised Date: March 18, 2020

You can define each row with different number of column count in SfListView by customizing the SpanCount property of LayoutManager in Xamarin.Forms.

XAML

<ContentPage xmlns:listView="clr-namespace:Syncfusion.ListView.XForms;assembly=Syncfusion.SfListView.XForms">
    <ContentPage.Content>
           <listView:SfListView x:Name="listView" 
                             GroupHeaderSize="0"
                             ItemSize="50" 
                             ItemsSource="{Binding contactsinfo}" >
                    <listView:SfListView.DataSource>
                        <dataSource:DataSource>
                            <dataSource:DataSource.GroupDescriptors>
                                <dataSource:GroupDescriptor PropertyName="CountryName"/>
                            </dataSource:DataSource.GroupDescriptors>
                        </dataSource:DataSource>
                    </listView:SfListView.DataSource>
                </listView:SfListView>       
    </ContentPage.Content>
</ContentPage>

C#

The SpanCount value calculated based on the maximum grouped items count from the GroupResult.

listView.Loaded += ListView_Loaded;
 
private void ListView_Loaded(object sender, ListViewLoadedEventArgs e)
{
    var displayItems = listView.DataSource.DisplayItems.Where(o => (o as GroupResult) != null);
    this.listView.LayoutManager = new GridLayout() { SpanCount = displayItems.Max(o => (o as GroupResult).Items.ToList<object>().Count()) };
}

Output

GridLayout
