There is a DeBexpress ListBoxEdit . He set the property DisplayMember="Naimenovanie" . This means that the property "Naimenovanie" is taken from the object for display. And now the question. I redefined the ItemTemplate
<dxe:ListBoxEdit.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding Naimenovanie}"> <TextBlock.InputBindings> <MouseBinding Command="{x:Static local:WndCatalogCommands.LoadBranchCommand}" MouseAction="LeftDoubleClick"/> </TextBlock.InputBindings> </TextBlock> </DataTemplate> </dxe:ListBoxEdit.ItemTemplate> What do I need to write in the Text property instead of {Binding Naimenovanie} , so that the value of the property specified in DisplayMember pulled up?
