Question

I’m trying to make a report treeview thing. Where I could write some text to have as a parent node, and if need be I’d add add strings as sub nodes to display some more information.

I made a report object:

public class Report
{
    private List<Report> reportList = new List<Report>();

    public string Text { get; set; }
    public List<Report> Reports
    {
        get
        {
            return reportList;
        }
        set
        {
            reportList = value;
        }
    }
}

Then I’d have a Report Collection that I would then feed into a treeview itemssource, but I have no idea how to create the bindings so that it will create the subnodes properly throughtout, I tried searching google, but I couldn’t find the correct way.

Can anybody inhere help me?

You need to use a HierarchicalDataTemplate

<TreeView ItemsSource="{Binding Reports}">
    <TreeView.Resources>
        <HierarchicalDataTemplate DataType="{x:Type local:Report}" ItemsSource="{Binding Reports}">
            <TextBlock Text="{Binding Text}" />
        </HierarchicalDataTemplate>
    </TreeView.Resources>
</TreeView>
