Hello,

I have a "add new record" row.  The first two columns of the grid are comboBoxes, and are bound to a list, for example:

myField.Settings.EditorType = typeof(XamComboEditor)

var style = new Style(typeof(XamComboEditor));

style.Setters.Add(new Setter(XamComboEditor.ItemsSource, dataContext.MyValues));

myField.Settings.EditorStyle = style;

I want the comboBox items in the second field to change depending on the value selected in the first field when editing the new record row.  I update the datasource correctly in the EditModeEnding event handler, but the second field's comboBox is not updated unless I reset the style (recreate the style from scratch).  But, when I do that, the value selected in the first comboBox is cleared?

What am I doing wrong?
