i have this NT addon that I made to remove all buttons except close on chart trader to prevent me from manual trades, it should only work on a specfic workspace called space1.It works but only for newly made chart windows after i load this script. When i restart NT , it either shows all buttons on all spaces, or just the close button on all spaces. How to fix this/ where is the flaw in this code

Hello Adam Klaus,

Please note injecting WPF into open windows is an advanced C# concept and is not fully supported by the Scripting Support team.

There can be limitations using unsupported code and advanced C# concepts in a NinjaScript, so your mileage may vary. As of now, we do not have any examples that can be used to navigate that path.


That said, here are some things to consider.

Are you adding debugging prints to understand the issue with Code.Output.Process()?

What is printing when you print the workspace name?

Are you detecting when the workspace changes?

https://forum.ninjatrader.com/forum/ninjatrader-8/add-on-development/1080008-any-way-for-addon-to-known-workspace-changed?p=1080112#post1080112

Are you adding objects to windows when the workspace name matches, and then removing the objects from the windows when the workspace name changes and does not match?
(There is similar concept for adding removing objects when a chart tab changes in the SampleWPFModifications help guide reference sample)


This thread will also remain open for any community members that would like to provide unsupported code for achieving this goal.
