Use [Component Message Handlers](https://docs.inductiveautomation.com/display/DOC81/Component+Message+Handlers). Read the docs and watch the videos. ---

Thank you. I have tried this Message Handler method in other screens. But here already I am passing parameter in popup, so I want to know how we can use in this. ---

If I understand your question, your situation is this: ```auto View1 [Main] + View2 + Embedded View: View 1 + Button1 + Button 1 - opens popup + Button 2 Popup + OK_button - needs to change View2/Button1 background color. ``` You seem to be trying to pass a value from Popup back to View1/View2/Button1. You can't pass values back through parameters. They are read only. The correct way to do this is via message handling. If my project tree is not correct then please clarify. ---

The indentation to show the hierarchy - if you had any - would be lost in your post. You need to use the \ code formatting button. See [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831). Please edit your post to fix it. ---
