Access to tab in hierarchy

[Hazeest]

I have a tab control in hierarchy

xaml:

<telerikNavigation:RadTabItem IsEnabled="{Binding Loaded}" Loaded="RadTabItem_Loaded" Margin="10,0,0,0" Height="24" FontWeight="Bold" FontSize="11" Foreground="Black"  Background="Gray">
                        <telerikNavigation:RadTabItem.Header>
                                <TextBlock Text="Linked titles" />
                        </telerikNavigation:RadTabItem.Header>

c#:

        private void RadTabItem_Loaded(object sender, RoutedEventArgs e)
        {
            RadTabItem tab = (RadTabItem)sender;
            if (!itemSpecs.ContainsKey(hier_selectedId.ToString()))
            {
                itemSpecs[hier_selectedId.ToString()] = new linnworks.cloud.dataModel.Inventory.StockItemClass();
            }
            tab.DataContext = itemSpecs[hier_selectedId.ToString()];

        }

itemSpecs[id].Loaded = false;

Then later in code I'm changing this to itemSpecs[id].Loaded=true (it binding with isEnabled)

itemSpecs is ObservableDictionary and it implements INotifyCollectionChanged, INotifyPropertyChanged

But I stil need to close and then again expand grid to enable this tab. 

Is there any way to get the tabItem by name in hierarchy so I could change isEnabled property in code.

Thanks.

Hello Hazeest,

The binding will be updated accordingly if the business object that is used as a DataContext for the TabItems is implementing the INotifyPropertyChanged interface. You mention that the collection you give as ItemsSource is observable, but that will help only if you add/remove entire items from it. So, if you make the items in that collection observable as well, you will be able to solve the problem.

All the best,
