Hi @Ganesh Panchal Can you explain a bit more about this scenario? Are you calling from one add-in (C#) to a task pane add-in (JS)? Or is this just one add-in and you need an event to let you know when a content control is entered? There is a onSelectionChanged event you can use. Would that work?
Thank you for the response. It would be more like, Taskpane Add-in(js) would communicate with other Addin. Basically, i want to access information(eg. Office version) of local system on which Taskpane is running.
You can get the Office version and some related information through Office.context.diagnostics. See https://learn.microsoft.com/javascript/api/office/office.context?view=common-js-preview#office-office-context-diagnostics-member
