Question

I was wondering how people handle a ListBox control that has no items? e.g. I want to bind a list of search results but if no results are found i would like to display ‘No results found’.

The way i currently tackle this is that i hide the listbox if the result set count = 0 and show a label with the ‘No results found’ message. Ideally i would like something like the ASP .NET datagrid EmptyTemplate solution.

Cheers

I’ve had some success with this code:

<Style TargetType='ListBox' x:Key='ListStyle' BasedOn='{StaticResource {x:Type ListBox}}'>     <Style.Triggers>         <DataTrigger              Binding='{Binding RelativeSource={x:Static RelativeSource.Self}, Path=Items.Count}'              Value='0'             >             <Setter Property='Template'>                 <Setter.Value>                     <ControlTemplate>                         <TextBlock>No items to display</TextBlock>                     </ControlTemplate>                 </Setter.Value>             </Setter>         </DataTrigger>     </Style.Triggers> </Style>
