Problem with ListBox

[Jason Callas]

I have a weird problem with a sorted ListBox which is bound to an ArrayList.

My ArrayList is holding a collection of custom objects. One of the public properties is called Name. When I add a few objects to the list and then bind the ArrayList to the ListBox (and after setting the DisplayMemeber property to "Name") the names show up like that are supposed to.

If I then add a new element to the ArrayList and call the Refresh method of the CurrencyManager object the ListBox shows the correct number of elements but instead of the value of the Name property it shows the full name of the class.

If I set the Sorted property of the ListBox to false everything works fine.

What am I missing or doing wrong?

Thanks

I posted sample code below :

TestClass

public class TestClass
{
private String _name;

public TestClass(String name)
{
_name = name;
}

public String Name
{
get { return _name; }
}
}

Form with ListBox (and button to add new element)

private void Form1_Load(object sender, System.EventArgs e)
{
_list = new ArrayList();
_list.Add(new TestClass("Jason"));
_list.Add(new TestClass("Mary"));

listBox1.DataSource = _list;
listBox1.DisplayMember = "Name";
}

private void button1_Click(object sender, System.EventArgs e)
{
_list.Add(new TestClass("Vinny"));

CurrencyManager cm = (CurrencyManager) listBox1.BindingContext[_list];
cm.Refresh();
}
