Hi there,
DisplayMemberPath value is ignored when the theme is set to LiveExplorer.
E.g. <ComboBox Height="23" Width="100" DisplayMemberPath="Name" />
The textbox of the ComboBox in collapsed state looks correct. However, when the expand button is clicked to reveal the list of possible values, the list contains the type names, e.g. MyNamespace.MyType rather than the "Name" property of each object.
I've tested it both in a separate ComboBox and as part of a cell template in a grid. Other themes don't have this issue.
Please check,
-Alec.
