Can Indicator to react in opening Indicators dialogue window?

[fx.practic]

I have an indicator that adds Grid on the chart.
And I need to hide Grid when a user opens Indicators dialogue window.

I tried to do it in OnStateChange() and forcing refreshing, but it not work.

Is it possible?

Hello fx.practic,

Thank you for your note.

This would not be supported. This may be possible however it would be unsupported and I'm unaware of any indicators which demonstrate how this could be done.

Please let us know if you need further assistance.
