Question

Currently I have a ListView (using the Details View). I would like to implement the behaviour whereby when a user selects a single item (log entry) the log entry expands (from one line to multiple lines) to provide more detailed information about the error that occured.

My question is this: Is this possible? If so, is there a good resource that I can use to help me?

EDIT:

If I HAVE to use WPF, then I guess Ill use the ElementHost with the control. However, I have absolutely no idea as to how about designing/coding/using WPF components. Any suggestions?

Edit: sorry this is wpf

The trick I used to achieve the same thing was creating a trigger to show a secondary grid which is defaulted to collapsed.

Try this out:

    <ListBox ItemsSource='{Binding}'>         <ListBox.ItemTemplate>             <DataTemplate>                 <Grid>                     <Grid.RowDefinitions>                         <RowDefinition></RowDefinition>                         <RowDefinition></RowDefinition>                     </Grid.RowDefinitions>                      <Grid Grid.Row='0' Height='20' >                         <TextBlock Text='Not Selected'></TextBlock>                     </Grid>                     <Grid x:Name='selectedOnlyGrid' Grid.Row='1' Visibility='Collapsed'>                         <TextBlock Text='Selected'></TextBlock>                     </Grid>                  </Grid>                  <DataTemplate.Triggers>                     <DataTrigger Binding='{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}, AncestorLevel=1}, Path=IsSelected}' Value='True'>                         <Setter Property='Visibility' Value='Visible' TargetName='selectedOnlyGrid' />                     </DataTrigger>                 </DataTemplate.Triggers>             </DataTemplate>         </ListBox.ItemTemplate>     </ListBox>
