Composite DisplayMember for ComboBox

Question

I need to display multiple pieces of data in a combobox, but I can't figure out how to do it.

Here's the code I'm trying to make work:

        innerBox.DisplayMember = @"t => t.TenantName + ""\t"" + t.Property.PropertyName + ""\t"" + t.RentalUnit.UnitNumber ";

But it doesn't work, this does though:

        innerBox.DisplayMember = @"t => t.TenantName";

How can I get the composite one to work?

Answer 1

This is not possible.

Instead, you should add a property to your underlying objects.

Answer 2

DisplayMember can contain only single property name! If you want composite output, you should subscribe to Format event and compose output string in code.
