	Hello MindFusion team! I use custom tooltip data in my application. I mentioned that after 4.0 version diagram items styles are still applied, but data context property is not being retrieved for the tooltip. I've attached these two projects to show how it works. Question is, how can I bind to DiagramItem in newer version?

	Hi there, Code <ToolTip x:Key="ItemToolTip" DataContext="{Binding Path=PlacementTarget, RelativeSource={x:Static RelativeSource.Self}}"> <TextBlock Text="{Binding CustomData}"/> </ToolTip> Relying on PlacementTarget being a diagram item will not work anymore with v4's presenter-based implementation. New diagram build here sets DataContext automatically to the item - https://www.nuget.org/packages/MindFusion.Diagramming.Wpf/4.1.4 so this Xaml should be enough now - Code <ToolTip x:Key="ItemToolTip"> <TextBlock Text="{Binding CustomData}"/> </ToolTip> Regards, Slavcho Mindfusion
