Question

I want to set the backgroun color for a GridViewColumn that is databound inside of a listview in WPF. I’m not sure how to ask this question being fairly new to WPF, otherwise I wouldn’t have bothered all of you.

I want to change the background color of the whole row, based on a bool flag in my databound object.

In this case, I have, well, a ‘CaseDetail’ object, that when there are internal notes ‘IsInternalNote’ I want the color of the row to change.

How can I pull this off in WPF?

What I have now, ( very simple ), which does NOT change the color.

<ListView ItemsSource='{Binding}' IsSynchronizedWithCurrentItem='True'  >             <ListView.View>                 <GridView>                     <GridViewColumn DisplayMemberBinding='{Binding Date, StringFormat=MMM dd\, yyyy h:mm tt}' Header='Date' Width='Auto' />                     <GridViewColumn DisplayMemberBinding='{Binding SubmittedBy}' Header='Submitted By' Width='Auto' />                     <GridViewColumn Width='Auto' Header='Description' x:Name='colDesc'>                         <GridViewColumn.CellTemplate>                             <DataTemplate>                                                               <ScrollViewer MaxHeight='80' Width='300'>                                     <StackPanel Orientation='Vertical'>                                         <TextBlock Text='{Binding Description}'  TextWrapping='Wrap'   />                                         <TextBlock Text='{Binding File.FileName}' TextWrapping='Wrap'  />                                     </StackPanel>                                 </ScrollViewer>                                                          </DataTemplate>                         </GridViewColumn.CellTemplate>                     </GridViewColumn>                                     </GridView>             </ListView.View>         </ListView>

I ran into a few troubles trying to do this, ended up like so

<ListBox ...>   <ListBox.ItemTemplate>     <DataTemplate>       <Border x:Name='BGBorder'>          <!-- -->        </Border>       <DataTemplate.Triggers>         <DataTrigger            Binding='{Binding Path=DataContext.IsAborted, RelativeSource={RelativeSource TemplatedParent}}'            Value='True'>           <Setter Property='Background' TargetName='BGBorder' Value='Red'>           </Setter>         </DataTrigger>       </DataTemplate.Triggers>     </DataTemplate>   </ListBox.ItemTemplate> </ListBox> 

There may be alternatives, but once I had it working, I stopped looking 🙂
