This is merely a follow up to my previous post:
How to enable the Conditional Formatting feature of the WinForms GridControl in the XAF GridListEditor and preserve ListView formatting settings between runs?

I want to share a similar solution for the TreeListEditor, which I coded and updated according to great customer feedback recently. You can learn more on this feature from the WinForms Controls > Controls and Libraries > Tree List > Conditional Formatting and TreeListOptionsMenu.ShowConditionalFormattingItem documentation.

Here are the steps needed to use the TreeListEditor in your XAF project:
1. In the Module Designer invoked for YourSolutionName.Module.Win/Module.xx file, add the Tree List Editor module to allow Visual Studio to automatically add required assembly references;
2. Copy and include this C# source file into YourSolutionName.Module.Win project (vb.net guys can either use this approach OR convert this code into their language using free tools).

Please track the corresponding Support Center thread to be automatically notified of any changes or other improvements in this regard.

As always, I am looking forward to hearing from you on whether you find this feature helpful for your apps.
