How to dispose of children of ListView in Xamarin.Forms (SfListView)

Platform: Xamarin.Forms |
Control: SfListView |
Published Date: April 17, 2020 |
Last Revised Date: April 17, 2020

You can dispose the custom view that was loaded in SfListView.ItemTemplate in Xamarin.Forms SfListView by customizing the ItemGenerator.


Created the custom Editor control in the PCL project that implements IDisposable.

namespace ListViewXamarin
    public class CustomEntry : Entry, IDisposable
        public CustomEntry()
            this.Text = "Country";
            BackgroundColor = Color.LightGray;
        public void Dispose()
            System.Diagnostics.Debug.WriteLine("custom control disposed");


Add the custom control in the ItemTemplate.

<syncfusion:SfListView x:Name="listView" ItemSize="60" ItemsSource="{Binding ContactsInfo}">
    <syncfusion:SfListView.ItemTemplate >
            <Grid x:Name="grid">
                    <ColumnDefinition Width="70" />
                    <ColumnDefinition Width="250" />
                    <ColumnDefinition Width="*" />
                <Image Source="{Binding ContactImage}" VerticalOptions="Center" HorizontalOptions="Center" HeightRequest="50" WidthRequest="50"/>
                <Label LineBreakMode="NoWrap" TextColor="#474747" Text="{Binding ContactName}" Grid.Column="1"/>
                <local:CustomEntry Placeholder="Enter here" Grid.Column="2"/>


Extend the ItemGenerator and ListViewItem, and override the Dispose method to dispose the custom control.

public class ItemGeneratorExt : ItemGenerator
    public SfListView listView;
    public ItemGeneratorExt(SfListView listView) : base(listView)
        this.listView = listView;
    protected override ListViewItem OnCreateListViewItem(int itemIndex, ItemType type, object data = null)
        if (type == ItemType.Record)
            return new ListViewItemExt(this.listView);
        return base.OnCreateListViewItem(itemIndex, type, data);
public class ListViewItemExt : ListViewItem
    private SfListView listView;
    public ListViewItemExt(SfListView listView)
        this.listView = listView;
    protected override void Dispose(bool disposing)
        if (this.Content != null)
            var grid = this.Content as Grid;
            var customEntry = (CustomEntry)grid.Children.FirstOrDefault(o => o is CustomEntry);
