I have a problem that I cannot see why it's not working. I have a 3 level Treeview with a converter which allow me to invert the two first level. On this TreeView I'm trying to bing the IsSelected Property but for a reason I don't understand it is never call in the ViewModel.
Here is the xaml.
<TreeView Margin="0,0,0,0" Padding="0,7,0,7" BorderBrush="{x:Null}" Background="#FFF8FAFB" Name="BusinessCaseTreeView"> <TreeView.ItemContainerStyle> <Style TargetType="{x:Type TreeViewItem}"> <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" /> </Style> </TreeView.ItemContainerStyle> <TreeView.ItemsSource> <MultiBinding Converter="{converter:BusinessCasesConverter}"> <Binding Path="BusinessCases"></Binding> <Binding Path="GroupByCreditor"></Binding> </MultiBinding> </TreeView.ItemsSource> <TreeView.Resources> <HierarchicalDataTemplate DataType="{x:Type converter:BusinessCaseTreeViewableFirst}" ItemsSource="{Binding SecondLevel}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding FirstLevel.Id}" Margin="10,0,0,0" Foreground="#FF03577A" FontWeight="Bold" /> <TextBlock Text="-" Margin="5,0,0,0" Foreground="#FF03577A" FontWeight="Bold"/> <TextBlock Text="{Binding FirstLevel.FirstName}" Margin="5,0,0,0" FontWeight="Bold" Foreground="#FF03577A" /> <TextBlock Text="{Binding FirstLevel.LastName}" Margin="5,0,0,0" FontWeight="Bold" Foreground="#FF03577A" /> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type converter:BusinessCaseTreeViewModelSecond}" ItemsSource="{Binding BusinessCases}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding SecondLevel.Id}" Margin="10,0,0,0" Foreground="#FF095A7C" FontWeight="Bold" /> <TextBlock Text="-" Margin="5,0,0,0" Foreground="#FF095A7C" FontWeight="Bold"/> <TextBlock Text="{Binding SecondLevel.FirstName}" Margin="5,0,0,0" FontWeight="Bold" Foreground="#FF095A7C" /> <TextBlock Text="{Binding SecondLevel.LastName}" Margin="5,0,0,0" FontWeight="Bold" Foreground="#FF095A7C" /> </StackPanel> </HierarchicalDataTemplate> <DataTemplate DataType="{x:Type business:BusinessCase}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="(" Margin="10,0,0,0" Foreground="#FF0B89BD" FontWeight="Bold" /> <TextBlock Text="{Binding Id}" Margin="1,0,0,0" Foreground="#FF0B89BD" FontWeight="Bold" /> <TextBlock Text=")" Margin="2,0,0,0" Foreground="#FF0B89BD" FontWeight="Bold"/> <TextBlock Text="{Binding CreationDate, StringFormat='{}{0:dd MMMM yyyy}'}" Margin="5,0,0,0" Foreground="#FF0B89BD" /> <TextBlock Text="-" Margin="5,0,0,0" Foreground="#FF0B89BD" FontWeight="Bold"/> <TextBlock Text="{Binding ClosureDate, StringFormat={}{0:dd MMMM yyyy}}" Margin="5,0,0,0" Foreground="#FF0B89BD" /> </StackPanel> </DataTemplate> </TreeView.Resources> </TreeView> I never arrive on the IsSelected setter in my ViewModel. If you have any idea, there are welcomed.
Thanks in advance
