How do I change the visual style of a listitem based on its bound value?
- by Rodd
I have a listbox (here's the xaml):
<ListBox MinWidth="300" ItemsSource="{Binding Relationships, Mode=OneWay}"
SelectedItem="{Binding SelectedRelationship, Mode=TwoWay}" SelectionMode="Single"
HorizontalAlignment="Left" >
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<CheckBox IsChecked = "{Binding IsPrimary}" IsHitTestVisible="False" />
<StackPanel Orientation="Horizontal" Grid.Column="1">
<TextBlock Text="{Binding RelationshipType}" FontWeight="Bold" Margin="0,0,5,0" />
<TextBlock Text="{Binding Status}" FontStyle="Italic" />
</StackPanel>
<TextBlock Text="{Binding UnitName}" Grid.Row="1" Grid.Column="1" />
<TextBlock Text="{Binding StartDate, Converter={StaticResource DateConverter}}" Grid.Row="2" Grid.Column="1"/>
<TextBlock Text="{Binding RetireDate}" Grid.Row="3" Grid.Column="1" />
<TextBlock Text="{Binding EndDate}" Grid.Row="4" Grid.Column="1" />
<TextBlock Text="{Binding ReasonForLeaving}" Grid.Row="5" Grid.Column="1" />
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
What I want to do is have each item in the listbox have one of 3 backgrounds (green if the value of IsPrimary = true, Orange if the EndDate value is empty and grey if the EndDate value is not empty.
Is there a way to template the listbox items so that they evaluate bound items to determine a view state or to have each listbox item bind to a value that I can set for each item in my viewmodel?
Thanks for your help.
