Binding WPF ListView to an Object with Child Collection

debugcn Published at Dev

I have the following object definitions:

public class FilterItem
{
    public string Type{get;set;}
    public List<string> Items{get;set;}
}

public class FiltersDataContext
{
    public string SearchText{get;set;}
    public List<FilterItem> Filters{get;set;}
}

I need to bind a ListView to the FiltersDataContext.Filters.Items child collection.

So far my xaml looks like this:

<ListView Name="ResearchFilters" ItemsSource="{Binding FiltersDataContext.Filters}">
    <ListView.ItemTemplate>
        <DataTemplate>
            <StackPanel  x:Name="FilterPanel">
                <CheckBox Content="{Binding Items, Mode=OneWay}" Tag="{Binding Path=Type, Mode=OneWay}" Checked="FilterCheckBox_OnCheck" Unchecked="FilterCheckBox_UnChecked" Click="FilteringResultSet"></CheckBox>
            </StackPanel>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

However, the ListView only ever displays a single CheckBox. Wondering where I'm going wrong.

You can achieve this without using ListView, but instead using ItemsControl

<ItemsControl ItemsSource="{Binding Path=Items}" ItemTemplate="{StaticResource CheckBoxItemsControlTemplate}">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <StackPanel />
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
</ItemsControl>

And in your resource dictionary, add this

    <DataTemplate x:Key="CheckBoxTemplate">
        <CheckBox  Content="{Binding Items, Mode=OneWay}" Tag="{Binding Path=Type, Mode=OneWay}"/>
    </DataTemplate>

    <DataTemplate x:Key="CheckBoxItemsControlTemplate">
            <ItemsControl ItemsSource="{Binding Path=FiltersDataContext.Filters}" ItemTemplate="{StaticResource CheckBoxTemplate}">
            </ItemsControl>
    </DataTemplate>

</ResourceDictionary>
