I have a listbox and would like to make some of the items in the listbox non-selectable based on the a field in the binding.

Ive tried setting the listboxitem.IsEnabled to false but this doesnt have teh desired effect.

Please could someone advise if this is possible.

Heres my datatemplate:

<DataTemplate x:Key="GridTemplate">
      <StackPanel Orientation="Horizontal">
           <Border Padding="{Binding EditorRow.RightBondIndent}" Width="50">
                  <Image x:Name="rightImg" Source="mat.png" Stretch="Fill"  />
           </Border>
      </StackPanel>
                <DataTemplate.Triggers>
                    <DataTrigger Binding="{Binding EditorRow.MaterialType}" Value="Blank">
                        <Setter Property="IsEnabled" Value="False" />
                    </DataTrigger>
                </DataTemplate.Triggers>
            </DataTemplate>

If you want to disable a single item inside the listbox you can try this. You can do it based on your binding property. Hope it helps.
