Use the ObjectListView project.cs

* Download the ObjectListView project
* Add the ObjectListView project to your project (right click on your solution; choose “Add...”, “Existing Project”, then choose the ObjectListView.csproj)
* In your project, add a reference to the ObjectListView project (right click on your project; choose “Add Reference...”, choose “Projects” tab; then double click on the ObjectListView project)
* there should now be a new section in your Toolbox, “ObjectListView Components”. In that section should be ObjectListView and its friends. (If you are using SharpDevelop, the section is called “Custom Components” and it appears at the bottom of the toolbox.) You can then drag an ObjectListView onto your window, and use it as you would a standard ListView control.
* add reference to your code
	using System.Collections;
	using BrightIdeasSoftware;
* sample code

	   // let the OLV know that a person node can expand 
        this.dataTreeListViewMain.CanExpandGetter = delegate(object rowObject) {
            return (rowObject is Person);
        };

        // retrieving the "things" from Person
        this.dataTreeListViewMain.ChildrenGetter = delegate(object rowObject) {
            Person person = rowObject as Person;
            return person.Things;
        };
        OLVColumn olvColumn1 = new OLVColumn();
        OLVColumn olvColumn2 = new OLVColumn();
        // column 1 shows name of person
        olvColumn1.AspectGetter = delegate(object rowObject) {
            if (rowObject is Person) {
                return ((Person)rowObject).Name;
            } else {
                return "";

        // add one root object and expand
        dataTreeListViewMain.AddObject(new Person("Person 1"));
       dataTreeListViewMain.ExpandAll();

	public class Person {
	    public string Name{get;set;}
	    public List<Thing> Things{get;set;}

	    public Person(string name) {
		Name = name;

	    }
