Dear Sirs,

I have multiple projects, but one of them is very special so it contains many custom fields that are required to be shown in the task tree view. The problem with that is the custom columns are shown on all projects. I want to only show the custom columns in task tree view only if the project title is "ABC", how can this be achieved?

I have tried the invisible and column invisible attributes and the get context method with and without a parent, all with no luck. 

Best regards,

Amir
