Question

Firstly:

        <ListView Height="259" HorizontalAlignment="Left" Margin="7,6,0,0" Name="dataListView" VerticalAlignment="Top" Width="899">
            <ListView.View>
                <GridView>
                    <GridViewColumn Width="240" Header="Test" />
                    <GridViewColumn Width="50" Header="Result" />
                    <GridViewColumn Header="Column 3" />
                </GridView>
            </ListView.View>
        </ListView>

is the definition in my XAML file.

Then when a test starts, I run:

dataListView.ItemsSource = tr.TestResultCollection;

In TestRunner.cs, I have created the Observable Collection of ArrayLists as such:

ObservableCollection<ArrayList> _testResultCollection = new ObservableCollection<ArrayList>();

and publicly refer to them as such:

        public ObservableCollection<ArrayList> TestResultCollection
        { get { return _testResultCollection; } }

Finally when I add to the collection, I use :

_testResultCollection.Add(SummaryVerificationTestCase1(dbs, dbd));

which adds an ArrayList to the collection. (Yes, a collection of ArrayLists, I know…)

However, what gets displayed in each Column is (Collection), (Collection, (Collection).

I see why. However, I’m not entirely certain what the neatest way around is. Normally in each GridViewColumn you give a binding like:

DisplayMemberBinding=”{Binding TestResult}”

But the ArrayList doesn’t have named components, just indices (0-2).

Is there a way to bind each column to the individual indices? Or have I missed something simple already?

Answer 1

Specify an index in the binding path:

       <GridViewColumn Width="240" Header="Test" DisplayMemberBinding="{Binding Path=[0]}"/>
       <GridViewColumn Width="50" Header="Result" DisplayMemberBinding="{Binding Path=[1]}"/>
       <GridViewColumn Header="Column 3" DisplayMemberBinding="{Binding Path=[2]}"/>
