How to access button content in OnBarUpdate

[kenz987]

NT8, Strategy, I have buttons in a grid, they work properly when clicked, but in OnBarUpdate I want to change the Content that is displayed, but I get an error saying it is owned by another thread.
I cant find a foreach ... ToList() to get to the button. Any help? Thanks.

Hello kenz987,

Thank you for your post.

You'd need to use a dispatcher since the button would be on a different thread (OnBarUpdate would be on an instrument thread while buttons would be on a UI thread).

I'd suggest reviewing this section of our help guide on multi-threading considerations with NinjaScript:

As well as this example that covers making changes to UI elements using WPF modifications:

Please let us know if we may be of further assistance to you.
