ComboBox doesn't update from "ValueMember" when this property is changed on object

In order to show the names of the objects added to the ComboBox I've set:
sausageChooserCombo.ValueMember = "Name";

- but when I change the "Name"-property on the objects, the ComboBox does
not update accordingly - it still shows the initial names... I've tried
this:

comboBox1.Refresh();
comboBox1.Update();

The objects are added manually to the ComboBox like this:
comboBox1.Items.Add(newObject);

The DropDownStyle is set to "DropDownList".


Any help is appreciated,
Thanks, Teis
 
Teis,

I'm afraid what you want is only possible when combobox is *bound* to an
object implementing IBindingList. You'll need to add a collection class
which implement IBindingList and set DataSource property of a combobox to an
instance of this class.

The much simpler way is to give up your custom classes and use DataTable.

HTH,
